    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
    • Illustrated instructions for use

    Passt nicht an meiner Kawasaki KLX250 (LX250S)

    Das Teil sieht gut aus und fühlt sich wertig an. Es funktioniert sicher auch gut, wenn man es denn einschrauben könnte. Leider passte die M12er Schraube nict in das M10er Gewinde an der Kawasaki. Das timmt irgendwas in der Zuordnung nicht. Ich habe heute extra nochmal geschaut, die Kawasaki KLX250 (LX250S) steht in der Liste drin, in der Realität passt es aber nicht.

    gute Idee aber leider nicht Perfekt

    Grundsätzlich eine geniale Erfindung, weil Praktisch in der Anwendung (wenns denn Funktioniert), und vor allem zu Schonung des Ölwannengewindes !
    Leider ist bei einem meiner Bikes schon zum 2. Mal das Ventil undicht..also wenn die Schutzkappe abgeschraubt wird strömt das Altöl nur so heraus.
    Deshalb habe ich sicherheitshalber immer das Schutzkappengewinde mit Gewindedichtmittel eingeschmiert und es funktioniert im Betrieb problemlos. Trotzdem ist das nicht Sinn und Zweck eines Produktes daß das Vielfache mehr kostet als eine herkömmliche Ölablassschraube !

    Lieber Louis-Kunde, wenn Sie keine Dichtheit Ihres Ventils erreichen, senden Sie uns den Artikel bitte zum Umtausch ein, solange er sich noch in der 2-jährigen Gewährleistung befindet. Mit freundlichen Grüßen, Ihr Louis Einkaufsteam
