Lube
 

What does everyone use to lube their...........gaskets/O-rings with? I was thinking Slick 50 or some other kind of teflon spray. Of course I'd spray my fingers and wipe the grease on the gasket.

I use food grade silicone lube, some pet stores sell lifeguard brand but you can get it at any plumbing store, I for sure would not use slick 50 or any petroleum based product.

I have never used anythimg, and have never had issues. I dont like the thought of adding such substances to the tank.

What about vegetable oil?

Yep, you shouldn't have to lube them at all.

I guess I will just go dry and roll the dice that I don't have problems.

I think most people that have issues attempted to use either a lubricant or a wrench. I rub gaskets clean under warm water with my fingers and hand-tighten.

I've used the silicon based o-ring lubricant from Lifeguard and it works great. I actually cannot assemble my red dragon pump on my skimmer without adding o-ring lubricant as the needle wheel housing fits extremely tight against the o-ring. Without the lubricant, you can only get the housing 9/10ths of the way back onto the body of the pump. The lubricant should also help prolong the life of the typical hard to find o-rings that most aquarium pumps, unions, and reactors use. This lubricant is reef safe and completely inert in salt water.

I use whatever oil is in the pantry. Get in trouble with the extra vergin olive oil though. I put on the skimmer cup o ring so I don't fight it and end up with a mess and anything else I want to move smoothly like the sticky tlf reactor threads.

I use the Lifegard wherever an o-ring won't squeeze out. It makes taking things apart later so much easier. I even used it on the ceramic washer on a noisy mp10wES wetside and it worked great
