The Ball Lock – Black – Disconnect is manufactured from a high quality plastic and is the most common Home-Brewer piece of equipment to attach to Ball Lock Kegs.
The Ball Lock Disconnect is a premium Ball Lock that is designed with Stainless Steel Barbs allowing high tolerance levels.
It is recommended to use the Ball Lock Disconnects in conjunction with John Guest or DMFit Push-In Fittings. These fittings will make joining tubing really easy.
