Frequently Asked Questions

What is a GRUVLOK clamp coupling used for?

A GRUVLOK clamp coupling joins grooved-end pipe in industrial piping systems for water, oil, or chemical transfer. It provides a leak-tight, flexible connection that accommodates thermal expansion and minor misalignment, commonly used in HVAC, fire protection, and process piping.

What are the specifications of the GRUVLOK 4 in x 4 in clamp coupling?

This GRUVLOK coupling is 4 in x 4 in, made of ductile iron with an EPDM seal, rated for 300 psi at 150° F. The manufacturer part number is 0390211142. It is designed for grooved-end pipe in industrial applications requiring reliable sealing and pressure containment.

Where to buy GRUVLOK clamp couplings worldwide?

3G Electric supplies GRUVLOK clamp couplings worldwide, handling full logistics and customs clearance for international orders. As a global industrial sourcing partner, we provide genuine GRUVLOK components like this 4 in x 4 in ductile iron coupling with EPDM seal, rated for 300 psi at 150° F.

How to install a GRUVLOK grooved pipe coupling?

Installation requires clean, properly grooved pipe ends. Lubricate the EPDM gasket, place it over one pipe end, then bring the second pipe into position. Fit the coupling housing over the gasket, insert bolts, and tighten evenly to the manufacturer's torque specification. Always follow GRUVLOK's published instructions.
