Universal Parts Manual Fuel Valve Petcock: M10x1.25
Description
Take full control of your fuel flow with the Universal Parts M10x1.25 Manual Fuel Valve Petcock. A robust alternative to temperamental vacuum-style petcocks, this manual valve threads directly into standard M10x1.25 tank bungs and gives you a simple, reliable On/Off lever to prevent carburetor flooding and fuel leaks during storage. Ideal for vintage mopeds, motorized bicycle builds, pit bikes, and small engines.
- M10x1.25 Male Thread: Standard metric thread for a secure, leak-free connection to integrated tank bungs or fuel manifolds
- Built-In Micron Screen Strainer: Captures sediment and debris before it reaches your carburetor, protecting against clogs
- Manual On/Off Lever: Tactile click-into-position action — easy to verify fuel status even with riding gloves on
- Zinc-Alloy Body and O-Ring: Fuel-resistant construction designed to withstand long-term exposure to ethanol-blended gasoline without degradation
- 6mm Barbed Outlet: Fits standard 1/4" fuel line
