Ball lock connector inner gasket

Anyone know of a McMaster Carr part # for these?

$0.35 isn’t bad, but they’re out of stock.  No emergency, but I have a QD missing a gasket which makes it unusable.

EDIT - Just realized I think that’s the wrong part.  I lost an o-ring on the inner stem.  That’s what I need to replace.  I think.  I better check tonight.  Never mind.

Yep, that is the part for the top cap, not the stem.

Thanks.  I also just found this: http://www.homebrewfinds.com/2011/08/keg-o-rings-v2.html

Nice to know the McMaster part # for the cap o-ring.  I honestly can’t recall which I’m missing.  Now I think it must be the cap since I cannibalized a gas in disconnect to make a liquid out one work.  My out is now both grey and black at the same time…

Oh that’s why that one disconnect was leaking

I think there is also a thread for silicone o-rings which I believe seal a little better.

That was easy, but what about a McMaster-Carr part number o-ring for the plastic firestone gas dip tube?

Thanks.  I found the right part #, which I suppose I should post.  For the cap ring it is: Silicone $6.11/100 - 9396K18  with the disclaimer that it’s not a square sided ring, but that it works.

For the plastic dip tubes I simply pulled them and replaced with a standard diptube o-ring and a stainless washer.  Works perfectly.

I also did one keg with two o-rings stacked, no washer.  That holds, too.  Same o-rings I use on all my kegs, bought in bulk from McMaster.
