Product Description

The GRUVLOK Rigid Coupling is a grooved pipe coupling (clamp type) in a 6 in x 6 in size, featuring an EPDM seal and ductile iron construction with grooved x grooved connections. It has a maximum operating pressure of 700 psi (MPN 390213816).

Frequently Asked Questions

What is a GRUVLOK rigid coupling used for?

A GRUVLOK rigid coupling joins grooved-end pipe in fire protection, HVAC, and industrial piping systems. It provides a leak-tight, mechanically strong connection that resists axial movement, making it suitable for high-pressure applications up to 700 psi.

What are the specifications of the GRUVLOK rigid coupling 390213816?

This GRUVLOK rigid coupling is a 6 in x 6 in clamp with an EPDM seal, ductile iron construction, and grooved x grooved connections. It has a maximum operating pressure of 700 psi. The manufacturer part number is 390213816.

Where to buy GRUVLOK rigid couplings worldwide?

3G Electric supplies GRUVLOK rigid couplings worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on the 6 in x 6 in model (MPN 390213816).

How to install a GRUVLOK rigid coupling?

Installation requires clean, properly grooved pipe ends. Lubricate the EPDM gasket, place it over both pipe ends, then position the coupling housing over the gasket. Tighten bolts evenly to the torque specified by GRUVLOK. Always follow the manufacturer's instructions for pressure ratings and bolt torque.
