Frequently Asked Questions

What is a GRUVLOK clamp coupling used for?

A GRUVLOK clamp coupling joins grooved-end pipes in fire protection, HVAC, and industrial piping systems. Its bolted ductile iron design and EPDM seal provide a reliable, leak-resistant connection rated for 1,000 psi maximum operating pressure.

What are the specifications of the GRUVLOK 0390095180 coupling?

The GRUVLOK 0390095180 is a 1 1/4 in x 1 1/4 in grooved pipe coupling with a bolted ductile iron body, EPDM seal, and 1,000 psi maximum operating pressure. It measures 4 1/2 in in length and is designed for mechanical pipe joining.

Where to buy GRUVLOK couplings in worldwide?

3G Electric supplies GRUVLOK couplings worldwide, handling full logistics and customs clearance for international orders. As a global industrial sourcing partner, we provide genuine GRUVLOK parts like the 0390095180 clamp coupling to customers across multiple regions.

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 halves and tighten the bolts evenly to the recommended torque for a 1,000 psi rated joint.
