UNI-Coupling

UNI-Coupling provides a fast, strong, and secure way to join pipes.

This stainless steel coupling is designed for dependable pipe connections in a wide range of applications. Its leak-resistant sealing system helps create a tight connection, while the shaped anchoring ring supports a firm and lasting hold.

With multiple types and sizes available, this coupling can be used to connect pipes made from different materials, even when the outside diameters are not the same.
