    This inline non-return (check) valve helps stop backflow in small-diameter fuel or coolant lines so systems stay primed and start reliably. It’s sized for common 5/16 in hoses and installs quickly in tight spaces.

    The lightweight nylon body resists corrosion and fuel degradation, offering long service life under constant vibration and temperature swings.

    • One-way flow check valve to prevent backflow in small fluid lines
    • Fits 5/16 in (8 mm) hose size for quick in-line installation
    • Durable nylon construction for resistance to fuel and heat
    • Compact design suited to tight engine-bay routing

    Installation Tip: Match the valve’s flow arrow to the fuel flow direction, cut the hose square, push the valve barbs fully into the hose, and secure with suitable clamps; check for leaks after priming.

    A practical, no-fuss way to maintain prime and reduce nuisance hard-starts on working equipment.
