Carbonation/Line Cleaning Cap/Counter Pressure PET Bottle Filling soda

I fill a 1.25 liter bottle with water (leaving head space),charge with co2, and leave the cap on while I store it in the refrigerator for later use during the day. The cap holds pressure. If I take this filling cap off and place the soda bottle cap on I lose some carbonation in the process, so I leave this stainless filling cap on the bottle. I'm impressed that it doesn't lose pressure for at least 24 hours. I haven't tested it longer than that. Some of the plastic caps will lose pressure if used in this manner according to reviews. My stainless filling cap doesn't have the iBrewing markings on the side. It has no markings. Works great and that's all I care about.

Use this to made fizzy water and it is great. Heavy and seems to be good quality.

Simple connector that enables a CO2 canister to connect (via Corny Keg disconnect) to a stardard plastic drinks bottle. Ideal for carbonating any drink - beer, water etc. Work as expeted. Well made.

Ben fatto! Da utilizzare con attacchi John Guest!

I bought it because it's material being 304 stainless steel, and it certainly has the heft to it. However, I found out that it has a slow leak and bottle that's more than 24 hours will lose it's carbonation. So I suspect it's not truly air tight

Just what I needed easy fits on a coke bottle
