Frequently Asked Questions

What is a GRUVLOK rigid bolted clamp coupling used for?

A GRUVLOK rigid bolted clamp coupling joins grooved-end pipe in industrial piping systems for water, oil, or gas. It provides a leak-tight, rigid connection rated up to 750 psi, suitable for HVAC, fire protection, and process lines where mechanical strength and alignment are critical.

What are the specifications of the GRUVLOK 0390010304 coupling?

The GRUVLOK 0390010304 is a 6 in x 6 in rigid bolted clamp coupling made of ductile iron with an NBR seal. It has a maximum operating pressure of 750 psi and an overall length of 11 in. It is designed for grooved-end pipe in industrial applications.

Where to buy a GRUVLOK 6 in rigid coupling for worldwide delivery?

3G Electric supplies the GRUVLOK 6 in rigid coupling (MPN 0390010304) for worldwide delivery. As a global industrial solutions provider, we handle full logistics and customs clearance to ensure the coupling reaches your site, whether for a plant in Europe, Asia, or the Americas.

How to install a GRUVLOK rigid grooved pipe coupling?

To install a GRUVLOK rigid coupling, ensure pipe ends are clean and grooved per manufacturer specs. Lubricate the NBR gasket, place it over one pipe end, then align the second pipe. Position the coupling housing over the gasket, insert bolts, and tighten evenly to the torque recommended by GRUVLOK.
