    Hello again.

    I recently got all new o-rings for all the caps and plugs for my next oil change on my 2011 TE 449. They are NBR material. However, I was reading about how the ZipTy oil filter cover (which I have) has a Viton o-ring, and now I'm wondering if I should use all Viton instead. The main issue might be the temperature rating. Any input?

    Why would it matter if they both seal and don't melt?

    Because I don't want to be riding along, only to find that the NBR either smolder or melt, then I end up with multiple, simultaneous oil leaks.

    Look up the specs for NBR and Viton, think about where they are and how hot they get and make your decision. If you are worried buy some Viton O-rings from McMaster Carr (or your vendor of choice).

    I have looked them up already, but I don't know hot those areas get, and I haven't been able to determine the OEM material. Regardless, I decided to order some Viton, just to be on the safe side. Lucky me -- they're 30 - 60 times as expensive as the NBR I got.
