Frequently Asked Questions

What is a GRUVLOK rigid coupling used for?

A GRUVLOK rigid coupling is used to join grooved-end pipe in industrial piping systems for water, oil, and other fluids. It provides a leak-tight, mechanically rigid connection that resists axial movement, making it suitable for fire protection, HVAC, and process piping where system rigidity is required.

What are the specifications of the GRUVLOK rigid coupling 390213864?

The GRUVLOK rigid coupling model 390213864 is a 6 in x 6 in clamp with a ductile iron body and NBR seal. It is rated for a maximum operating pressure of 700 psi and connects grooved x grooved pipe ends. This coupling is designed for rigid mechanical joining in industrial applications.

Where to buy GRUVLOK rigid couplings worldwide?

How to install a GRUVLOK rigid coupling?

To install a GRUVLOK rigid coupling, ensure pipe ends are clean and grooved per manufacturer specifications. Lubricate the NBR gasket and place it over one pipe end. Slide the coupling housing over the gasket, align with the second pipe, and tighten bolts evenly to the recommended torque. Do not over-tighten.
