Frequently Asked Questions

What is a GRUVLOK clamp coupling used for?

A GRUVLOK clamp coupling joins grooved-end pipe in fire protection, HVAC, and industrial piping systems. It provides a flexible, leak-tight connection that accommodates thermal expansion and minor misalignment, reducing stress on equipment and supports.

What are the specifications of the GRUVLOK 0390007557 coupling?

This GRUVLOK bolted clamp coupling has a 2 in x 2 in fitting pipe size, ductile iron construction, NBR seal, and a maximum operating pressure of 750 psi. Overall length is 6 3/8 in. It is designed for grooved pipe systems requiring reliable, high-pressure connections.

Where to buy GRUVLOK couplings for worldwide delivery?

3G Electric supplies GRUVLOK clamp couplings worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on the 0390007557 or other GRUVLOK grooved pipe couplings.

How to install a GRUVLOK bolted clamp coupling?

Ensure pipe ends are clean, grooved, and lubricated. Place the gasket over both pipe ends, then position the coupling housing over the gasket. Insert bolts and tighten evenly to the torque specified by GRUVLOK. Do not over-tighten; verify the gasket is fully seated before pressurizing.
