But the walmart thing.
WIX site/catalog can see gasket size (and more) on any filter you choose.

BigDawg,

I'm not suggesting that an O-ring is what you need, because I have no idea, but....

O-ring grooves are not typically "concave". Parker specs dimensions for O-ring grooves as square, or slightly tapered sides (up to 5° per side), and up to a small fillet where the sides meet the bottom. This applies to both radial and face applications. I machine O-ring grooves all the time, and I have yet to machine any that were concave. O-rings are meant to compress.

That said, I'd think a Viton O-ring of the appropriate size would serve the purpose well enough.

Carry on.

Thanks. Brad.

Griff,

Are you suggesting to remove the gasket from a purchased filter? I guess I never thought about it, but I didn't realize they could be removed. I figured they were affixed somehow.

Thanks. Brad.

They generally use an interference fit of some sort.

That’s what I did bought a oil filter with the right size gasket that I needed.I just took the old gasket and just matched up.

They actually come out fairly easily. Lots of times when I remove an oil filter, the filter gasket sticks to the filter mount.

Griff,

Hum.... I've obviously never had that happen. I learn something new every day.

Thanks. Brad.

My dad once changed the oil in his car and accidentally left the old filter seal on the housing. Was quite the mess when he started it up. Now I always check to make sure the old seal is still on the old filter

Ryan,

My dad taught me to use the oil on the old filter seal to wet the seal on the new filter before installing it. I guess I've got a default failsafe built into my process. This explains why I didn't know they can come off.

Thanks. Brad.

I do that too, even though the Mobil 1 filters say you don't have to. Prob 1 out of 5, the gasket still sticks to the mount.
