Small O ring in Oil Filter
I just changed the oil filter with a wix it came with the 0 ring for the cap but not the little one on the filter bottom Is it needed Thanks

My FRAM filter has both the big and little "O" ring on the replacement filter. I suspect it should be there.
|
I have more filters i looked and they are black I think i just missed it old one was yellow but am wondering the purpose of small one
|
The small one seals the in/out going oil, without it the oil could bypass the filter. This statement is based solely on my feeble observations, and may be totally incorrect.

I think you are correct, donbrew...... If your filter came without the small o-ring, it's defective, don't use it and take it back...... Check the box of the new one and make sure it's complete.
|
Yeah the little o-ring is needed, I'd be concerned enough to take the filter back out to confirm that its there, otherwise the oil will bypass the filter.
|
am convinced going to take it back out to see
|
Just checked and it has the 0 ring. I didn't look if or where it sealed anyone know?

I always open the oil filter boxes at the store.. Nothing worse that getting home & missing stuff.
PS: Adding a wipe of clean oil over the O-rings prior to install helps prevent any possible chaffing during install..:thumb: |
My STP flter came with both O rings the big one was of course in the box and the tiny one was already on the filter . One on the filter was green and the larger one for the cap was black not that it really matters ! Other than the OEM cap O ring I have is green just useless info I am sure .
As My wife says Iam a NUT anal ass I wasn't sure about the small O ring and went out and pulled the oil filter at 2 am :D to be sure things were right . I just didn't remeber seeing the small O ring when I changed it a few weeks ago . so I had to look only been drove a couple 100 miles so would not a been a big deal but all was right it was there now I can sleep .:thumb: |
