Vaseline As Beer Gun Lube?

[matt84]

Is there anything particularly wrong with using vaseline as beer gun lube? I just serviced a second hand beer gun (now I have two :icon_chickcheers: ) and quick-disconnect with it as I don't feel like making yet another trip to the LHBS.

Yes. Vaseline is petroleum based, so it will dissolve the rubber seals. Better off with KY.

You can also go to any dive shop and get a little tub of the silicone grease they use to service dive gear. Food grade, not petroleum based and a tub lasts forever.
