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 locked connection that resists axial movement, making it suitable for high-pressure applications up to 750 psi.

What are the specifications of the GRUVLOK rigid coupling 390213208?

This GRUVLOK rigid coupling is a 2-1/2 in x 2-1/2 in rigid bolted clamp made of ductile iron with an EPDM seal. It has a maximum operating pressure of 750 psi and is designed for grooved pipe systems. The manufacturer part number is 390213208.

Where to buy a GRUVLOK rigid coupling worldwide?

3G Electric supplies the GRUVLOK rigid coupling 390213208 to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. As a global industrial solutions provider, we source this genuine component and support your order from inquiry to arrival.

How to install a GRUVLOK rigid coupling?

To install a GRUVLOK rigid coupling, ensure pipe ends are clean and grooved per manufacturer specifications. Lubricate the EPDM gasket, place it over one pipe end, then slide the coupling housing over both pipe ends. Tighten bolts evenly to the recommended torque to achieve a rigid, leak-free joint.
