A strong lawn mower fuel shut-off valve fits the fuel line’s inner diameter, matches the engine’s replacement part number, and closes fuel flow when the mower is stored. For many small engines, a 1/4-inch inline valve is the common choice, and Hipa Inline Fuel Valve offers broad listed compatibility with several Briggs & Stratton, Toro, Snapper, and Kohler references. This roundup compares ten options, including single valves, multipacks, and kits with clamps, hose, or a filter.
Check your current valve or engine manual before ordering: a matching line size alone does not confirm part compatibility. The listed products also vary in material and application range, so the best choice depends on whether you need a general replacement, a specific cross-reference, or extra installation parts.
Hipa Inline Fuel Valve is the leading choice for a typical mower because it is listed for 1/4-inch inner-diameter fuel lines and names replacement references for Briggs & Stratton, John Deere, Toro, Snapper, and Kohler applications. Its broad compatibility also extends to other small engines, including riding mowers, garden tractors, pressure washers, and snowblowers. Confirm the existing part number and line size before buying; the listing describes alternative material options, so check the specific item details if material is a deciding factor.

#3 · Brass Construction
3. Buckbock Brass Valve
- Inlet Connection Size: 0.25 in
- Outlet Connection Size: 0.25 in
- Thread Size: 0.25 in
- Material: Brass
Best for: Brass valve with ethanol limit.
Why it ranks #3: Specifies brass construction and 1/4-inch connections, plus a clear warning that its valve is for gasoline with up to 10% ethanol.
Its brass construction and stated fuel limit make this Buckbock valve especially specific for buyers who want both material and fuel guidance. The listing permits gasoline containing up to 10% ethanol, giving owners a clear boundary to consider before using it on a 1/4-inch fuel line.
Buckbock identifies brass construction and 1/4-inch inlet and outlet connections, connecting the material choice to a defined small-engine line size. Its replacement references include John Deere AM36141 and AM107340, Briggs numbers such as 494768 and 698183, and Toro 54-3150. The stated 10% ethanol ceiling is important for fuel selection: the description warns that higher concentrations can corrode the valve's sealing ring.

- 1/4-inch inlet and outlet connections
- Names John Deere, Briggs, and Toro references
- States a maximum 10% ethanol fuel limit
- The listing warns that fuel above 10% ethanol can corrode its sealing ring.

- Inlet Connection Size: 0.25 in
- Outlet Connection Size: 0.25 in
- Thread Size: 1/4 inch
- Material: Metal
Best for: Two-valve pack with four clamps.
Why it ranks #4: Supplies two metal 1/4-inch valves and four clamps, with compatibility references for Briggs & Stratton, Toro, Murray, and Snapper.

#5 · Best Storage Pair
5. CLSR2U Two-Pack Valve
- Inlet Connection Size: 0.25 in
- Outlet Connection Size: 0.25 in
- Thread Size: 1/4 inch
- Material: Plastic
Best for: Storage-minded small-engine owners.
Why it ranks #5: Includes two plastic valves for 1/4-inch fuel lines; the listing explains using shutoff to let the carburetor run dry for storage.
Its fuel-cutoff function lets you stop the supply and run the carburetor dry, addressing fuel buildup during short or long storage. The two-valve pack uses 1/4-inch connections for small-engine fuel lines, making it a practical option for owners maintaining several compatible machines or keeping a spare on hand.
CLSR2U specifies 1/4-inch inlet and outlet connections, matching the 1/4-inch inner-diameter fuel lines described for riding mowers, garden tractors, push mowers, pressure washers, snowblowers, and other small engines. Closing the valve and letting the carburetor run dry supports storage maintenance without relying on draining the tank. The listing includes two valves, so a multi-machine owner can keep another available. Its plastic construction keeps the valve material distinct from the metal options in this roundup.
- Two shutoff valves are included
- 1/4-inch inlet and outlet connections
- Supports running the carburetor dry for storage
- Listed for several small-engine equipment types
- Plastic construction may not suit buyers seeking a metal valve.

6. Bopurtotly 494768 Valve
- Inlet Connection Size: 0.25 in
- Outlet Connection Size: 0.25 in
- Thread Size: 1/4"
- Material: Stainless Steel, Brass, or Aluminum
Best for: Broad replacement-number matching.
Why it ranks #6: Includes a clamp and lists 1/4-inch connections alongside replacement references for Briggs & Stratton, John Deere, Toro, Snapper, and Kohler.

The listing names multiple replacement references, including Briggs & Stratton 494768 and 698183, John Deere AM107340, Toro 54-3150, and numerous Kohler engine models. That breadth helps buyers compare an existing part or engine reference before maintenance. Both connection sizes are listed as 0.25 inches, which makes the fuel-line dimension explicit. One valve with a clamp is included, so the package suits a single repair rather than furnishing multiple shutoff points.
- Broad set of named replacement references
- Lists many Kohler engine models
- 1/4-inch inlet and outlet connections
- One clamp is included with the valve
- Only one valve is included for a single repair.
Skip it if you want two valves for separate machines; Tnisesm's pack includes two valves and four clamps.

7. Hipa Metal Valve
- Inlet Connection Size: 0.25 in
- Outlet Connection Size: 0.25 in
- Thread Size: 1/4-inch
- Material: Metal
Best for: Metal valve for common engines.
Why it ranks #7: Offers a 1/4-inch metal valve with listed Toro and Snapper references and stated fitment across several mower-engine brands.
Its metal construction is the clearest differentiator for owners selecting a 1/4-inch shutoff valve for named mower and small-engine applications. Hipa lists Toro and Snapper replacement references alongside compatibility with John Deere, Kawasaki, Kohler, Craftsman, Poulan, and Cub Cad equipment.
The 0.25-inch inlet and outlet dimensions establish the listed line size, while the metal material gives buyers a straightforward construction detail to weigh during maintenance-part selection. Hipa identifies Toro 54-3150 and 1-603770, plus Snapper 3-4212, 2-4507, and 7034212 references. Its broader fitment description names several engine and equipment brands, which helps users narrow their search by maker. The supplied specifications do not identify a bundled hose or clamp, so the valve itself is the focus.
- Metal construction
- 1/4-inch inlet and outlet dimensions
- Names Toro and Snapper replacement references
- Lists several compatible engine and equipment brands
- The listed specifications focus on the valve, not a hose-and-clamp kit.
Skip it if you need a bundled hose and clamps; BlueStars includes a fuel line and two clamps with its valve.
This suits owners seeking a metal 1/4-inch valve whose Toro, Snapper, or broader named-brand references match their equipment. Consider the listed valve dimensions and whether your repair requires separate line hardware.

Bullwall names replacement references including 692008, 493960, 07-406, 698183MA, MU698183, and 494768, then lists numerous Kohler CH and CV models. That detail helps owners compare an existing part number and engine family when selecting a replacement. The straight inline format and 1/4-inch inner-diameter line specification help define where it fits in a fuel-line repair. Its stated product information centers on the valve rather than describing a multi-piece installation kit.

9. BlueStars 48568 Kit
- Inlet Connection Size: 0.25 in
- Outlet Connection Size: 0.25 in
- Thread Size: 1/4"
Best for: Valve kit with replacement fuel line.
Why it ranks #9: Pairs a valve with fuel line and two clamps, but its listed Scag 48568 and Oregon 07-403 references make it a more specific fit.
Its included fuel line and two clamps make the BlueStars kit a ready-to-plan choice for a 1/4-inch inline valve replacement. The 180-degree ball-valve description and named Scag, Oregon, Sunbelt, and Rotary references give buyers specific configuration and part details to compare.
BlueStars includes one shutoff valve, one fuel line, and two clamps, combining the listed components needed for a line replacement. The valve is specified for 1/4-inch fuel line and described as a 180-degree ball valve, helping buyers assess both size and configuration. Its replacement references include Scag 48568, Oregon 07-403, Sunbelt B1SB868, and Rotary 868. The listing also describes the valve as removable for maintenance, supporting service access when replacement is needed.
- Includes one fuel line and two clamps
- Specified for 1/4-inch fuel line
- 180-degree ball-valve configuration
- Names Scag, Oregon, Sunbelt, and Rotary references
- The kit includes one valve, not a multi-valve pack.

10. SYOWADA Valve Kit
- Inlet Connection Size: 0.25 in
- Outlet Connection Size: 0.25 in
- Thread Size: 1/4 inch
Best for: Valve-and-filter maintenance kit.
Why it ranks #10: Includes a valve, fuel filter, and clamps, but its broad repair-kit fitment spans several engine and valve references that require careful matching.
Its included fuel filter and hose clamps make this SYOWADA kit more than a standalone shutoff valve, combining several items for a fuel-line service. The 1/4-inch connections and wide replacement list cover references associated with Briggs, Kawasaki, Snapper, and other named small-engine applications.
The package lists a fuel shutoff valve, fuel filter, and hose clamps, bringing several fuel-system service components together for a maintenance task. Its 1/4-inch inlet and outlet connections provide the stated line size. Compatibility references include 493960, 494768, 698183, Kawasaki 49019-0014 and 49019-0707, plus Snapper and Tecumseh numbers. That range can help buyers compare their machine's part reference while planning a repair, though exact fit still depends on the listed references matching their equipment.
- Includes a fuel shutoff valve, filter, and hose clamps
- 1/4-inch inlet and outlet connections
- Names Kawasaki replacement references
- Lists Briggs-related, Snapper, and Tecumseh references
- The listing does not specify the number of hose clamps included.
Skip it if you need a specifically enumerated clamp quantity; Tnisesm lists four clamps with its two-valve pack.
This kit suits owners handling a fuel-line service who can match one of its listed replacement references and value the included filter and clamps. Check the stated 1/4-inch connection size against the repair.

View on AmazonAvoiding fuel-line fit and compatibility mistakes
A 1/4-inch connection is not enough by itself to confirm that a replacement valve will fit your mower. These listings commonly specify 1/4-inch inlet and outlet connections, but they also cite different replacement numbers, including Briggs & Stratton 698183, Toro 54-3150, and Scag Match the number on the old valve or your engine documentation to the listing before relying on a brand name alone.
Also distinguish an inline valve for a 1/4-inch inner-diameter hose from a valve meant for a different installation arrangement. The BlueStars kit, for example, names Scag 48568 and Oregon 07-403, while several general-purpose listings cite 698183 and related numbers.
If the original part number is unavailable, compare the valve shape, hose size, and connection orientation with the removed part. Do not assume that a broad compatibility list guarantees a fit on every mower from a named manufacturer.
Fuel and storage considerations for shut-off valves
A shut-off valve can help isolate fuel for storage, but these listings do not establish that every valve tolerates every fuel blend or storage condition. Buckbock specifically says its valve may be used with gasoline containing up to 10% ethanol and warns that a higher concentration can corrode the internal sealing ring. Treat that limit as product-specific rather than applying it to the other valves.
CLSR2U describes closing the valve and letting the carburetor run dry to help prevent fuel buildup during short- or long-term storage; this is a stated use, not a guarantee against carburetor problems. Before storage, follow the mower and engine manufacturer’s instructions for fuel handling.
Inspect a valve and hose for seepage after installation, and replace a component that does not close or seal properly. Some kits add clamps, a hose, or a filter, but included parts do not prove that the full kit matches your engine.
How to Choose a Lawn Mower Fuel Shut-Off Valve
Fuel-line size and replacement references
Look for a valve that matches both the hose’s inner diameter and the original part number. Most products here specify 1/4-inch inlet and outlet connections or a 1/4-inch fuel-line fit, but their replacement references differ. Hipa Inline Fuel Valve lists multiple Briggs & Stratton, John Deere, Toro, Snapper, and Kohler numbers; Oregon 07-406 lists Briggs & Stratton 698183, 494768, and 493960.
BlueStars 48568 instead names Scag 48568 and Oregon 07-Buyers replacing a common 698183-style valve may prefer a broadly cross-referenced option; owners of a Scag application should start with the narrower BlueStars references and verify the original part number.
Valve material and fuel limits
Check the stated material and any fuel-use warning rather than assuming all valves are alike. The listings describe plastic, brass, metal, composite, or alternatives such as brass, stainless steel, or aluminum. Buckbock specifies brass and says its valve is suitable for gasoline containing up to 10% ethanol, but not more; that warning is specific to its product.
Oregon 07-406 specifies composite material, while CLSR2U specifies plastic. Buyers who want a stated material can narrow the choice using those details; buyers choosing another listing should confirm its exact item material and fuel guidance in the product information.
The supplied data does not establish comparative service life or durability, so material alone should not be treated as a performance test.
Package contents and installation needs
Choose the package according to the parts you actually need to replace. Several options are single valves, while CLSR2U and Tnisesm supply two valves; Tnisesm also includes four clamps. BlueStars includes one valve, fuel line, and two clamps, and SYOWADA lists a valve, filter, and hose clamps.
Bopurtotly specifies one valve with a clamp. A buyer replacing only a failed shut-off may prefer a valve-only option and reuse suitable existing hose hardware.
Someone maintaining more than one machine may find a two-piece pack useful, while a buyer replacing worn hose or filter components can consider a kit that names those parts. Check the mower’s actual hose and installation requirements because included components do not establish universal compatibility.
Which fuel shut-off valve should I choose?
For a common 1/4-inch mower line with a replacement number covered by several listings, choose Hipa Inline Fuel Valve: it has broad stated cross-references and is the strongest general-purpose match. Pick Oregon 07-406 Valve if you want a composite valve with clearly named Briggs & Stratton replacement numbers. Choose Buckbock Brass Valve if brass construction matters and its stated 10% ethanol limit suits your fuel.
For spare valves and clamps, Tnisesm Valve Set includes two valves and four clamps; CLSR2U Two-Pack Valve also supplies a pair and describes a storage use. If your application points specifically to Scag 48568 or Oregon 07-403, consider BlueStars 48568 Kit instead.
In every case, confirm the original part number and fuel-line size before installation.
Frequently Asked Questions
How do I confirm whether my mower uses a 1/4-inch fuel line?
Check the fuel line’s inner diameter, not its outside diameter. If you can safely remove a section, measure across the opening; otherwise, consult the mower or engine documentation or compare the line with a known measurement. Also verify the original valve’s part number, since matching line size alone does not confirm compatibility.
Can I use an inline shut-off valve with gasoline containing ethanol?
Only if the specific valve listing or manufacturer information confirms compatibility with your fuel. Ethanol tolerance can depend on the valve’s materials, and the product titles here do not establish a universal limit. Check the details for the exact item and fuel blend before installing it; do not assume every valve is suitable.
How do I safely install and check a mower fuel shut-off valve?
Work with the engine off and cool, away from flames or sparks, and prevent fuel from spilling. Confirm the valve matches the fuel-line size and replacement application, then follow its installation instructions and secure the connections as directed. Before starting the mower, check carefully for leaks; stop if fuel escapes or the fit is uncertain.
Why should I check the original part number as well as the line size?
A matching line size does not by itself establish that a valve suits your mower. Compare the original valve’s part number with the replacement references in the listing, and check the engine or mower application. For example, some listings name specific replacement numbers, while others describe broader small-engine use.
When is a two-valve set useful?
A two-valve set may suit you if you want a spare or need valves for more than one compatible application. Some listings also include clamps, while another describes a storage use. Check the exact package contents and confirm each valve’s line size and replacement fit before relying on it.
Final Words
For a common mower with a 1/4-inch fuel line, Hipa Inline Fuel Valve is the strongest general-purpose match when its stated replacement references cover your original part number. Choose a more specifically listed replacement when your application calls for it, such as the Oregon option for named Briggs & Stratton numbers. For any choice, verify the original part number, line size, package contents, and fuel compatibility before installation.
