Description

Sump Plug Sealing Washer for the engine lubrication system. It seats between the oil drain plug and the sump pan boss, sealing the joint so the plug can be torqued down without weeping oil.

The washer takes up the surface between the plug head and the casting and is renewed at each oil change to maintain a reliable seal. The same washer also serves at the oil filter adaptor and cylinder block drain on applications that use it there.
