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 rigid or flexible connection rated for 300 psi at 150° F, using a ductile-iron housing and EPDM seal for reliable sealing in water and dilute chemical service.

What are the specifications of the GRUVLOK 0390211084 coupling?

The GRUVLOK 0390211084 is a 2-1/2 in x 2-1/2 in grooved pipe coupling made of ductile iron with an EPDM seal. It has a maximum operating pressure of 300 psi at 150° F. 3G Electric supplies this genuine GRUVLOK component for industrial piping applications worldwide.

Where to buy GRUVLOK clamp couplings worldwide?

How to install a GRUVLOK grooved pipe coupling?

To install a GRUVLOK coupling, ensure pipe ends are clean and grooved per manufacturer specifications. 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 for a leak-free joint.
