John Guest Superseal Barb - 5/16 Superseal x 1/4 ID Barb

The John Guest SuperSeal barb connector is specifically designed to provide extra grip on stainless steel tubing. Each fitting in this series features a collet with integrally molded stainless steel teeth and a hand-operated nut and wedge-shaped plastic washer that applies extra pressure to the collet and the double O-ring seals. This allows the collet teeth to bite thoroughly into the tube to provide grip, while at the same time, compressing the O-rings to further improve the seal.
