UNISEAL PIPE COUPLINGS

UP TO 3,000 LB.

STAINLESS STEEL PIPE COUPLINGS

The Uniseal Pipe Coupling (WU) enhances traditional pipe unions by using a spiral-wound gasket for a leak-tight seal, similar to flange joints. This design eliminates the common issues of leakage and maintenance associated with ground joint finishes. The replaceable gasket prevents failures due to poor mating surfaces, allowing components to be individually stocked and replaced without needing matched parts.

FEATURES

 

  • Leak-tight seal

  • Lower maintenance and labor costs

  • Lower inventory costs

  • One Uniseal satisfies all pressure series of flanges in pipe sizes 1/2" to 2"

  • Easy installation, there is no danger of damaging the seal during installation as it is fully protected from over-torquing

  • Costly removal of sections of pipe to replace leaky unions is eliminated

  • Completely interchangeable components for all size classes

  • End connections can be socket welded, threaded, or a combination of both
