Oil Filter Cap O-Rings

[PJ Moran]

Yes, this has been "beat to death", but I could not find my answer...

Everyone complains about the cost of these "special" and "unique" O-rings that apparently are available only through a Sea Doo dealer. Well, I ain't buyin' it!

These are bound to be standard sizes and common materials. It's just that the size is not known / revealed. Does anyone know the actual sizes of the three rings required? I find it hard to believe one couldn't go down to their favorite auto parts store and purchase them individually by size.

If someone has a set of unused rings and a quality dial caliper, they could measure the rings for us

I always buy the oil change kit and end up throwing away new o-rings every other year. Hmmm.

I'm sure the o-rings can be 2nd sourced, but make sure the elastomer is up to the task. I suppose Kalrez would be more than adequate but check the application tables to confirm.

Why not just purchase the kit? To avoid expensive GOTCHA's, we use the OEM stuff in our shop and Sierra marine parts are quality as well, no fly-by-night stuff though.

Cost. I don't mind paying more for the good stuff, but I have a problem with highway robbery.

Shouldn't need anything exotic for this application. Kalrez are super expensive. We use them in our robotic paint applications due to compatibility issues with our solvent and activator.
