Frequently Asked Questions

What is a GRUVLOK rigid bolted clamp coupling used for?

A GRUVLOK rigid bolted clamp coupling joins grooved-end pipe in fire protection, HVAC, and industrial piping systems. It provides a leak-tight, rigid connection rated for 300 psi, suitable for water, oil, and other non-corrosive fluids.

What are the specifications of the GRUVLOK 0390060143 coupling?

The GRUVLOK 0390060143 is a 6 in x 6 in rigid bolted clamp coupling made of ductile iron with an EPDM seal. It has a maximum operating pressure of 300 psi and is designed for grooved-end pipe connections.

Where to buy GRUVLOK couplings worldwide?

3G Electric supplies genuine GRUVLOK couplings worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this 6 in rigid clamp coupling.

How to install a GRUVLOK rigid clamp coupling?

To install a GRUVLOK rigid clamp coupling, ensure pipe ends are clean and grooved. Lubricate the EPDM gasket, place it over both pipe ends, then position the coupling housing over the gasket. Tighten bolts evenly to the manufacturer's torque specification.
