This Beer Carbonation Tester Quick Disconnect Insert O-Ring is made out of Buna-N Nitrile and is meant to serve as a replacement part for the Taprite Draft Beer Carbonation Tester. It attaches to the quick disconnect hose end allowing you to perfectly seal your tester once the inlet/outlet hose is inserted.
Please Note: It is NOT compatible with standard quick disconnects. It is only to be used with the Taprite Beer Carbonation Tester.
