Product Description

The GRUVLOK Clamp Coupling is a 1 1/2 in x 1 1/2 in grooved pipe coupling with a bolted, ductile iron design and an EPDM seal. It has a maximum operating pressure of 1,000 psi and a length of 4 5/8 in (MPN 0390095206).

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. This 1 1/2 in bolted ductile iron model with EPDM seal handles up to 1,000 psi, providing a reliable, leak-resistant connection for water and other compatible media.

What are the specifications of the GRUVLOK 0390095206 coupling?

This GRUVLOK coupling has a 1 1/2 in x 1 1/2 in size, bolted ductile iron construction, EPDM seal, maximum operating pressure of 1,000 psi, and overall length of 4 5/8 in. The manufacturer part number is 0390095206.

Where to buy GRUVLOK couplings worldwide?

3G Electric supplies GRUVLOK couplings worldwide, handling full logistics and customs clearance for international orders. As a global industrial sourcing partner, we provide this 1 1/2 in clamp coupling with EPDM seal and 1,000 psi rating to customers across multiple regions.

How to install a GRUVLOK grooved pipe coupling?

Installation requires clean, properly grooved pipe ends. Lubricate the EPDM gasket, place it over both pipe ends, then position the ductile iron housing over the gasket. Insert bolts and tighten evenly to the manufacturer's torque specification. Always follow GRUVLOK's published installation instructions for the 1,000 psi rating.
