gasket lube?

[NM_Shooter]

I need an o-ring lubricant for use on a vehicle.  I've been trying to find a non-adhesive silicone lubricant for o-rings and have struck out.  What can I use, and where can I find it?

Can I use a dielectric grease similar to the stuff that is used on spark plug boots?

I use power punch or motor oil for o rings. What is it for?

Shooter,

When I used to work on BIG hydraulic presses we used:

1. Parker O-Ring Lube

2. regular old plain petroleum jelly

I use plain auto or hydraulic oil.  There is a silicone spray available at automotive places if you want a silicone product. 

They are made to handle oils in most cases.

Matts Pools (and others I suppose)

I have bought a silicone based, non hardening, lube from them in the past.

+1 on Petroleum Jelly.

This is for on intake plenum for the air filter on a Polaris RZR. 

I'm spooked about using petroleum jelly, as if the gasket / o-ring is petroleum based (many are) it will degrade the fit over time.

I use food grade silicone for o-rings on kegs.  Works well, I got the can I use at a brew store, but I imagine you can look around and get them other places.
