Petroleum jelly will actually deteriorate rubber over time. You might want to avoid using petroleum jelly.

Can't you just wet the O rings to seal your canister?

Mike is correct; petroleum jelly will mess up your o-rings and probably isn't great for your tank. If you feel compelled to (very lightly!!!) coat your o-rings, use a non-toxic, food-grade silicone grease. You can get it at a scuba supply shop; it's used for tank and regulator o-rings.

Good to know--my filter came with vaseline for the O-rings and instructions for applying it.

Hmm. Just received an Eheim Ecco. After I set it up, I read the instructions (oops!) which recommended using petroleum jelly. I'll check the materials tonight to see the exact wording.

I don't doubt that they do. Most people already have a jar of petroleum jelly at home or know where to buy one. Few people even know that silicone grease exists. It's not like the petroleum jelly is going to make the o-ring rot away overnight, but silicone grease is a better product for this sort of thing.

When you are diving at 100+ feet or in a cavern or cave, you use what is best for your equipment because your life depends on it. I suppose if you are just putting an o-ring into your filter, you can use petroleum jelly, olive oil, margarine, or even spit.

They make a clear lubricant gel for the o rings on ice cream machines. Probably get it at a restaurant supply store.
Or at the risk of sounding crude....KY jelly. Same stuff, different package. No petroleum base, think it's vegetable based, probably soy.

KY would be a better way to go.

Both plumbing supply outlets and pool and/or spa supply outlets will carry goop that is good for o-rings -- for lubricating and for preserving, that is fairly cheap and won't mess up yout water. THis type of item is easily found on the Internet as well.

Sometime air leaks into the canister and creates tinny bulles in the tank. Lubing the o-ring can stop the leak.
