Specially designed to provide extra grip on stainless steel tubing, John Guest® SuperSeal fittings feature a collet with integrally molded stainless steel teeth similar to the standard Super Speedfit® or push-to-connect designs. They also incorporate a hand-operated nut and wedge-shaped plastic washer to apply extra pressure to the collet and the double O-ring seals. This causes the collet teeth to bite thoroughly into the tube to provide grip while compressing the O-rings to further enhance sealing. This functionality makes SuperSeal fittings ideal for potable liquids and other food-quality applications that involve stainless steel tubing. The spanner tool, sold separately, is used when securing SuperSeal fittings to stainless steel tubing. One side is for use with 1/4" and 5/16" SuperSeal fittings, and the other side works with 3/8" SuperSeal fittings.
