Regulator Bellville washer lubricant
- Thread starter Skip-in-WV
- Start date
I ordered a can of "corrosionx" based on Scott's suggestion. He has not steered me wrong yet.
The two times I've had a regulator apart so far I've just put a very thin film of silicone grease on the washers and the regulators work well. The Huma in my Caiman come with a huge amount of what appeared to be silicone grease on the washers and none on the o-ring below the adjustment screw. So it stopped working. So I ordered a rebuild kit and while I was waiting I took it apart and fixed these issues and it works great now. I have the kit for next time. O-rings should always get a little silicone grease I think but avoiding corrosion is probably the bigger need for the washers.

In there someplace among the 100's of Regulators Serviced/Rebuilt a constant in most cases has been ... if or when using MFG provided service kits, the unknown outside visual I.D. is ... WHAT IS the O-rings material ?
Between Buna/N and some Nitrile, others a Polyurethane, the Oils / Lubricants each specific material will tolerate or requires can become somewhat GREY
The "ONLY" lubricant that is universally Inert for all the possibilities is "SILICONE" ... So after years of Doing, Trying, Re-Servicing & Discovery I've gone full circle to simply using HEAVY wt Silicone oil/s.
Indeed some lubes excel when & where you know the o-rings composition. Unknown is the real crux & when in doubt use Silicone.
JMO ...
NOW as OP asked .... BEVEL Lubrication, certainly NOT silicone as it as a metal on metal lubricant is Horrid !!!!!!!!!!!!!!!!!!!!
