Float refill o ring grease

**buildakicker** · 01-19-2017, 11:02 PM

Hey all, I cannot find my little bag of grease for my refill kit. Plenty of o rings. Is there a certain type of grease I must use? BCA sells it with the kit, but doesn't specify anything about it.

Thoughts?!

Just found it says vacuum grease in a PDF online. Will any ole Dow brand vacuum grease work then?

Generally dow33 works best on any o-rings with a pneumatic purpose. Especially dynamic ones.

This is a useful thread.

So according to BCA, the important issue is the cold temp rating on the grease. The scuba shop here has Dow Molykote, which I used, since the low temp is -40°c. New o ring and that grease, no leak and full bottle. Oh, btw, using the water bath (water bottle) works great to keep the canister cool. Didn't lose any pressure from what the shop filled it too... FYI.
