The Stahlbus®-petroleum drain valve will easily replace your existing drain plug. When changing the oil, unscrew the cap and insert the hose connector using the quick release. Only when this is locked, the valve opens and the oil can be drained into the container provided. When the hose connection is released the valve closes automatically and only the protective cap needs to be activated. Advantages at a glance: • No contact with oil • Easy handling by quick release • drain plug cannot be lost • None risk of burns from hot oil • seal exchange is not necessary • cup wire is spared • double outlet fuse (protective cap and valve) • suction connection possible • dosed exhaust sampling or overfilling • cover to protect against leakage from O-rings • Change the oil without tools So changing the oil is fun!
