Gruvlok 8 in Rigidlok Coupling

The Gruvlok 390013571 Rigidlok Coupling is an 8 inch ductile iron fitting designed for grooved piping systems. It provides a rigid mechanical joint suitable for industrial and commercial installations.

Class 150 rating with 750 psi maximum operating

Rated for Class 150 service on Schedule 40 pipe, the coupling handles a maximum operating pressure of 750 psi at 150 degrees Fahrenheit. The 600 psi designation indicates the standard working pressure envelope for typical applications.

Painted ductile iron construction for durability

The painted ductile iron body resists corrosion in normal service environments. The rigid design minimises angular movement at the joint, reducing stress on connected equipment during pressure cycles.
