which o-rings to lubricate

[finflipper49]

I have a OMS wing and want to change o-rings on the inflater after cleaning some corrosion and I was wondering if I need to lubricate them. I'm going to order o-rings from DiveGearExpress. What o-rings do you guys lube and how much lube do you use. I'm not concerned about o-rings inside the regulator but any other ones that I might want in a save a dive kit. which ones should I keep on hand. Thanks for your input.

You'll want to lube just about any o-ring (except the 014 and 214's on your tank valves) that's used in your gear. When lubing you should only use enough to make the surface of the o-ring look shiny, any more than that and you've just created a "grunge magnet". For save-a-dive kit starting out: 003, 010, 011, 012 for LP hoses & HP hoses/spool & 014's for yoke valve.

If it's a static O ring i.e doesnt move, generally it needs no lubrication. On my inflators I only lubricate the 2 small O rings on the spindle. Here's a link on servicing a generic K inflator (thanks DSS) that you might find helpful.
