    Stahlbus Oil Drain Valve

    stahlbus Oil Drain Valves

    Oil changing can actually be fun! With this system you can drain your oil safely and cleanly, without any spillage or dripping, or even getting your hands dirty.
    Simply replace your existing oil drain plug with the stahlbus Oil Drain Valve. To change the oil, unscrew and remove the protection cap and fit the quick-release hose connector. The valve only opens once the connector is locked in place, and the oil can then be drained into a suitable container. When you disconnect the hose connector, the valve closes automatically, and you simply screw the protection cap back on.

    The benefits at a glance:

    • No contact with the oil
    • Easy-to-use quick-release connector
    • Drain plug cannot be lost
    • No danger of scalding from hot oil
    • No seal to change
    • Oil sump thread is not damaged
    • Double leakage protection (protection cap and valve)
    • A suction device can be connected
    • A small quantity can be drained for taking a sample or in the event of overfilling
    • O-ring prevents loss of protection cap
    • Oil change without tools
    • No type approval or entry in vehicle documents required!


    • Valve and hose connector (CNC precision-machined from high-grade steel)
    • Copper seal
    • High-quality hose approx. 400mm long
    • Protection cap made of anodised aluminium
