Hard to get completely tight on a tap-a-draft

Review by Peter on 5/13/2011

Better price here than some other places, especially with a 10+ discount - I lose these with my growlers and tap-a-drafts. The only problem is that I have a hard time getting the cap on tightly enough to seal a tap-a-draft when charging - I kept hearing a hiss and tightening the cap more. I'm going to try leaving more headspace in the bottle next time, though.

Better !!!!

These caps will do the job. The caps on my original bottles do not seal well and laek co2 as the bottles condition. These are made to seal!

inconsistent quality

Review by Jason on 10/31/2012

I ordered 10 of these caps to check them out and see if they fit my bottles. (I'm bottling my own kombucha in used GT's kombucha bottles.) The caps fit well and were strong enough to withstand the CO2 pressure when I used them with a 2-stage bottling method. I decided to order another 40. However, my second batch did not perform as well. Approximately 1 out of every 5 cracked while I was putting them on for the first time.

Polyseal caps

Review by George on 1/13/2013

I found these caps superior to any others I have tried. I experimented bottling in my growlers (4) and they worked great, not a single one went flat due to leakage. I have also found utilizig a small amount of keg lube assists with tightening and sealing. They have performed their function superbly for me. Thumbs up!
