Highest quality seal growler caps

I want to increase my supply of growler caps, but want to get ones that will will absolutely provide a great seal for many months, in case I need to fill off the kegerator to make room for more full kegs, or some other lesser emergency like vacation travel or a party.

With help from the forum and online research it looks like I have two options:

  1. the reusable black plastic cone seal, poly seal caps that are recommended for a long seal.

or

  1. metal single-use screw cap with canning-jar-type inside perimeter seal. I still haven’t found a good source for these. A picture of one face up (black cap/white inside) can be seen on the “Caps” page at:

I haven’t yet contacted Brewpack yet to see if they sell to non-wholesalers like me, but was wondering a) what is your experience with either/both of these caps, b) does anybody have a good online source for the metal sealing caps indicated above, and c) have you had good luck with long-term seal with the cone seal poly seal caps. Those are what I currently use and they seem to work fine, but I’ve never used them for months at a time.

I have won part of the conquest for information. The gasket liner material inside the metal cap is called plastisol, same as for canning jars.

I found 38 mm plastisol lined growler caps at F.H. Steinbart:

I’m going to buy some and try them out!

Yeahhh! Props to Mullerbrau who said that these type of caps work to keep carbonation even as long as a year. If I do empty out a keg into growlers, first I’ll increase the carbonation so what little carbonation they lose in transfer won’t matter, and I’ll be sure to put those caps on TIGHT.
