I just need the washer, i have the filter. Where can i buy a washer for the drain plug? Hardware store? And what size?

thanks.

Check your filter box... when I purchase a Mann filter > it comes with the copper drain plug washer and a new rubber O-ring for the oil filter cap.

Actually > I reuse the copper washer over and over >> and it does not leak.

Personally > if you currently have a copper washer on the drain plug now > I wouldn't sweat it

kgl

i dont think i have one. cant see it and it drips from the plug.

My c-class uses a washer with a 12/16 inch overall diameter and a 9/16 inner diameter, or real close to that.

I would get it from the dealer. Shouldn't cost too much... (famous last words)

got one from lowes. thanks for the sizes. i will just make sure the next filter i buy has the washer in it with the seals.

I try to never reuse nylon washers if it can be helped.The heat they are exposed to makes them brittle over time.Then they crack,and you've got a leak.But the copper plugs can be reused many times without worry as long as every thing is clean when you reinstall the drain plug.Just check them for cracks from overtightening,or pitting from dirt.You don't allways get a new one with the filter.I don't know if they forget to put it in the box,or if simply fell out someplace.If you don't get a new one,and the old one looks good,don't worry about reusing it.
