How/When to use Keg Lube
So I bought a tube of keg lube and will be kegging for the first time tonight. In all the instructions I've found though, there's no mention of the lube.

Do I use it on all rubber parts or just the main o-ring? Do I put it on before or after sanitizing?

Thanks for the info!

I use it sparingly on all of my rubber o-rings (gas in tube o-ring, beer-out tube o-ring, lid o-ring, even the pressure relief valve rubber part, and the poppet valve rubber). I clean and sanitize everything before applying. After everything is assembled I spray the posts and disconnects with sanitizer before connecting them.

A little goes a long way, don't slather the stuff on.

Same as Schnitz...any thing rubber gets it.

same here as well, and yeah a thin coating is all you need. if the gasket looks 'wet' then it has enough on it.

I put a liberal amount on the lid and post o-rings before I transfer beer to my serving kegs.

Its an assembly lube. I'd think if you use starsan, its slippery enough if you assembly it while still wet.

I'd argue to say that it also:
1. Lengthens the life of your rings by preventing them from drying out.
2. Helps prevent leaks. Good example was on the sprayer I converted to clean out my lines. It would not pressurize so I slathered some keg lube on the o-ring at the top and she now holds pressure just fine.

I wish I would have bought a tube instead of a jar. That stuff doesn't come off your hands the greatest.

i use a moderate amount on all o-rings as well. The one place i vary is on one keg where the lid-opening has been bent (flared out a little), so it can leak. On that keg, i load the lid o-ring up with the stuff, which prevents the bend from bleeding out CO2. took me 2 tanks to track down the leak, but a little extra lube sealed it right up.
