Pipe Couplings and Fittings

The Uniflex Coupling

The Uniflex Coupling (SUA) – by Nicholson – has successfully solved frequent leakage, intensive maintenance, and stocking difficulties associated with ground join-pipe unions. The SUA is a modified forged steel or stainless pipe union utilizing a Spiral-Wound Gasket to provide a leak-tight joint. This design, similar in principle to flange joints, has been proven in the field for many years. Because the joint seal is formed by the replacement gasket (not a ground joint finish); failures caused by poor mating surfaces are eliminated. Components may be stocked and replaced individually because mated parts are not required for sealing.
