For use with Stainless Steel Tubing
The SI Range of inch-size push-in fittings is offered for tube sizes 1/4" O.D. to 3/8" O.D. Superseal is a special fitting designed to provide extra grip on stainless steel tubes.
The Superseal design features a collet with integrally molded stainless steel teeth similar to the standard Super Speedfit design, but incorporating an additional hand-operated nut and wedge shaped plastic washer to apply extra pressure to the collet and the double O-ring seals. This ensures that the collet teeth bite thoroughly into the tube to provide grip, while at the same time compressing the o-rings to further enhance sealing.
Like other John Guest Fittings, Superseal is suitable for potable liquids and other food quality applications.
