Frequently Asked Questions

What is a GRUVLOK flex bolted clamp coupling used for?

A GRUVLOK flex bolted clamp coupling joins grooved-end pipe in fire protection, HVAC, and industrial piping systems. Its ductile iron body and EPDM seal handle pressures up to 1,000 psi while allowing limited angular movement for misalignment.

What are the specifications of the GRUVLOK 0390004570 coupling?

The GRUVLOK 0390004570 is a 6 in x 6 in flex bolted clamp coupling made of ductile iron with an EPDM seal. It has a maximum operating pressure of 1,000 psi and is designed for grooved pipe connections in commercial and industrial applications.

Where to buy GRUVLOK couplings worldwide?

3G Electric supplies GRUVLOK couplings worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on the 6 in flex bolted clamp coupling (MPN 0390004570).

How to install a GRUVLOK flex bolted coupling?

To install a GRUVLOK flex bolted coupling, ensure pipe ends are clean and grooved per manufacturer specs. Place the gasket over both pipe ends, then position the coupling housing over the gasket. Tighten bolts evenly to the recommended torque to achieve a leak-free seal.
