on/off teflon oring

[river031403]

what size/type oring can replace teflon oring if not running co2. I did a search but could not find the answer. :cool:

Use the small top urethane oring for the retro on-off assembly. It is the correct size. It isn't quite as tight as the teflon one.

It's a size 006 urethane, 90 durometer.
