Frequently Asked Questions

What is a GRUVLOK rigid coupling used for?

A GRUVLOK rigid coupling is used to join grooved-end pipes in industrial systems such as HVAC, fire protection, and process piping. It provides a secure, leak-resistant 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 390213610?

The GRUVLOK rigid coupling model 390213610 is a 3 in x 3 in grooved pipe clamp with an EPDM seal, rated for a maximum operating pressure of 750 psi. It is constructed from ductile iron with grooved x grooved connections, designed for rigid pipe joining in industrial systems.

Where to buy GRUVLOK rigid couplings worldwide?

3G Electric supplies GRUVLOK rigid couplings worldwide, handling full logistics and customs clearance for international orders. As a global industrial sourcing partner, we provide genuine GRUVLOK parts like the 390213610 coupling to customers across multiple industries, ensuring reliable delivery to your site.

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 the pipe ends, then position the coupling housing over the gasket. Tighten bolts evenly to the recommended torque to achieve a rigid, leak-free joint rated for 750 psi.
