Frequently Asked Questions

What is a GRUVLOK rigid coupling used for?

A GRUVLOK rigid coupling joins grooved-end pipe in fire protection, HVAC, and industrial piping systems. It provides a leak-tight, mechanically strong connection that resists axial movement, making it suitable for high-pressure applications up to 700 psi.

What are the specifications of the GRUVLOK rigid coupling 390213816?

This GRUVLOK rigid coupling is a 6 in x 6 in clamp with an EPDM seal, ductile iron construction, and grooved x grooved connections. It has a maximum operating pressure of 700 psi. The manufacturer part number is 390213816.

Where to buy GRUVLOK rigid couplings worldwide?
