HPENP Cut-Off Fuel VALVES For Scag 2-Way Valve
Best for Scag equipment requiring a direct, factory-style replacement. This two-way valve uses 1/4″ barb fittings and is designed for dual-tank configurations. The on-off-on operation helps isolate fuel flow to one tank or both tanks as needed. It’s a straightforward swap for professionals executing quick maintenance or replacements on Scag ZTRs and similar mowers.
Why chosen: It mirrors the OEM two-way setup and includes the necessary configuration to control dual tanks. Limitation: May require confirmation of model compatibility before purchase to ensure an exact match.
BlueStars 1-633347 Cut-Off Valve With Kit
Best for buyers needing an exact-match replacement across multiple lawn brands. This 2-way valve uses a 1/4″ barb and ships with a fuel filter kit, fuel line, and clamps. Ideal for landscapes where a single valve must fit Exmark, Husqvarna, Scag, or related models. It is better for those who want a ready-to-install kit rather than sourcing separate components.
Why chosen: It provides an exact-match cross-compatibility claim and a complete kit, which simplifies installation. Caution: Verify engine model and part numbers to guarantee an exact fit before ordering.
SeaSense 1/4-Inch NPT Female Three-Way Valve
Choose this if you need a three-port setup to divert flow among three sections of pipe. While not a typical two-way valve, it provides practical versatility for complex fuel routing in boats or larger equipment that require multiple branch connections. It’s best for users who want more than two ports while retaining a compact valve footprint.
Limitation: It is a three-way valve, so it does not fit a strict two-port requirement for standard Scag or Exmark setups. Best used where a third port is necessary.
HPENP Fuel Shut Off Valve Two-Way
Best for Zero Turn Mowers and Garden Tractors needing a straightforward two-way shut-off. This valve uses 1/4″ barb fittings and a dual-tank configuration in a compact form. It is a reliable alternative to OEM valves for quick replacements on popular mower lines.
Why chosen: It mirrors the standard two-way design with an On-Off-On configuration, making maintenance predictable. Caution: Ensure the part number matches your engine’s requirements to avoid mismatches.
Mikatesi 2Pack Two-Way Cut-Off Valves
This option offers a budget-friendly two-pack for users who want extra valves or replacements across multiple units. It is best for workshop use or fleet maintenance where multiple machines share the same valve type. Includes clamps for quick installation and broader compatibility with Scag, Exmark, Husqvarna, and similar models.
Why chosen: The 2-pack provides value and flexibility for ongoing maintenance. Limitation: Check compatibility with your specific model numbers to confirm exact fit before installing.
Buying Guide
What should I look for in a 2-way fuel valve?
- Compatibility: Verify part numbers (E633347, 1-633347, 482212, 539102679, etc.) and the mower brand to ensure a match.
- Flow configuration: On-Off-On is common for dual-tank systems; On-Off for simple single-tank shut-off. Select based on your system design.
- Fittings: Confirm 1/4″ barb fittings if your lines match this size. Consider hoses, clamps, and possible adapters.
- Kit contents: Some listings include fuel filters, lines, or grommets—these can simplify installation but verify actual contents.
- Durability: Look for solid materials (metal over plastic where possible) for long-term fuel compatibility and corrosion resistance.
Installation Considerations
- Safety: Work in a well-ventilated area away from sparks and ignition sources.
- Gas compatibility: Use valves rated for gasoline and ethanol-blended fuels as applicable.
- Seal quality: Ensure new gaskets and O-rings are included or sourced to prevent leaks.
- Orientation: Follow manufacturer guidance for valve orientation to ensure correct fuel flow direction.

FAQ
- Q: Are two-way fuel valves compatible with all lawn mowers? A: They are compatible with many models, but you should verify model numbers and part numbers (E633347, 1-633347, 482212, 539102679, etc.) before purchasing.
- Q: Do these valves come with hoses and clamps? A: Some listings include hoses and clamps; others may require separate purchases.
- Q: What does On-Off-On mean? A: It indicates the valve can route fuel from either tank to the engine or close flow to both tanks as needed.
- Q: Can I replace a 3/8″ valve with a 1/4″ valve? A: No, fittings and hose sizes must match the fuel line; verify the barb measurement on your existing setup.
- Q: Is a three-way valve necessary for most mowers? A: For most dual-tank configurations, a two-way valve is sufficient; a three-way valve is only needed if you require an additional branch port.
- Q: Should I consult a technician for installation? A: If you are unsure about fuel lines and seals, seek professional assistance to avoid leaks and safety hazards.
