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 rated for 300 psi at 150° F, using a ductile-iron housing and EPDM seal.

What are the specifications of the GRUVLOK 0390000248 coupling?

The GRUVLOK 0390000248 is a 1-1/2 in x 1-1/2 in grooved clamp coupling made of ductile iron with an EPDM seal. Its maximum operating pressure is 300 psi at 150° F. It is designed for grooved pipe systems in commercial and industrial applications.

Where to buy GRUVLOK clamp couplings worldwide?

3G Electric supplies GRUVLOK clamp couplings worldwide, handling full logistics and customs clearance. As a global industrial sourcing partner, we provide genuine GRUVLOK parts like the 0390000248 coupling to customers across 14 departments, including combustion and pumps.

How to install a GRUVLOK grooved pipe coupling?

To install a GRUVLOK coupling, ensure pipe ends are clean and grooved per manufacturer specs. Lubricate the EPDM gasket, place it over both pipe ends, then position the ductile-iron housing over the gasket. Tighten bolts evenly to the torque recommended by GRUVLOK.
