Cut-Off Fuel VALVES For Scag 2-Way 1/4" Barbs Steel Fuel Oil Gas Petcock in Line Valve 482212, E633347, 1-633347, Husqvarana 539102679 with Fuel Filter Kit

What It Is

This is a replacement fuel shut-off valve assembly for Scag and Husqvarna commercial mowers, combining a 2-way, 1/4" barbed steel petcock with an inline fuel filter. It allows you to stop fuel flow for service or storage while filtering debris.

Fitment & Compatibility

Before buying, check:

• Barb size: Must be 1/4" (outer diameter of barb). Measure your existing hose ID—this valve fits 1/4" ID fuel line.
• OEM cross-references: Scag 482212, E633347, 1-633347; Husqvarna 539102679. Not universal—verify your mower’s OEM part number.
• Mower models: Commonly fits Scag Turf Tiger, Cheetah, Wildcat, and Husqvarna Z242F, Z254, Z4218. Not for zero-turn mowers with 3/8" or 5/16" fuel line.
• Valve type: 2-way (on/off), not a 3-way or primer valve. Steel body, zinc-plated—avoid if you need plastic or brass.

Key Things to Know

• Installation: Simple—cut fuel line, clamp valve in line. No special tools needed, but use fuel-rated clamps (not zip ties).
• Filter included: The kit comes with a small inline filter. Check if your mower uses a separate filter elsewhere—this one may be redundant.
• Leak risk: Steel barbs can corrode over time, especially with ethanol-blended fuel. Inspect annually for rust or pitting.
• Gotcha: Valve handle may be stiff initially. Work it open/closed a few times before final install to ensure smooth operation.

Should You Buy It

If you own a Scag or Husqvarna with a 1/4" fuel line and need a direct replacement for the listed OEM parts, this is a solid, affordable option. It’s not for universal fit—measure first. Best for DIYers who want a drop-in fix with a bonus filter, not for commercial users needing brass or stainless durability.
