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 provide a flexible, leak-resistant connection rated for 600 psi, accommodating minor misalignment and thermal expansion.

What are the specifications of the GRUVLOK 0390000222 coupling?

The GRUVLOK 0390000222 is a 1-1/4 in x 1-1/4 in flex bolted clamp coupling made of ductile iron with an EPDM seal. It has a maximum operating pressure of 600 psi and is designed for grooved pipe connections in commercial and industrial applications.

Where to buy GRUVLOK couplings in worldwide?

3G Electric supplies GRUVLOK couplings worldwide, handling full logistics and customs clearance for international orders. As a global industrial sourcing partner, we provide genuine GRUVLOK parts like the 0390000222 flex bolted coupling to customers across multiple regions.

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 secure, leak-free joint rated for 600 psi.
