SI Inch Superseal® Fittings are specially 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.

All SI Inch Fittings are Lead Free.
