PERA Ball Lock MFL Dis-Connect Set with Swivel Nuts 5/16 Gas Barbed with clamp

Perfect. I make my own carbonated water with a 20lb CO2 tank setup. Used to use the MoreBeer carbonator caps but they're like $15 a piece now (used to be like $5 if you bought 12 at a time or something). Much better deal on these! Fit those red caps you can get for like $5/ea in a 4 pack on amazon too.

I liked this product for the first few months of use, but then out of nowhere some seal must have broken because it no longer functions. If I turn on the tank, Co2 goes rushing straight out of this ball lock. It appears to be leaking from the inside center, the part where the carbonation cap inserts.The company agreed to send me a replacement part. It arrived promptly. :)

Simple to use.I make my own seltzer and this makes it easy.

Snaps on and off easy - unlike some of the off brand knock-offs.

Easy to use
