Product Description

The GRUVLOK Rigid Coupling is a rigid bolted clamp-type grooved pipe coupling, sized 2 in x 2 in, constructed from ductile iron with an NBR seal, and rated for a maximum operating pressure of 750 psi. This coupling provides a secure, leak-resistant joint for grooved-end piping systems.

Frequently Asked Questions

What is a GRUVLOK rigid coupling used for?

A GRUVLOK rigid coupling creates a secure, leak-resistant joint in grooved-end piping systems for industrial applications such as HVAC, fire protection, and process piping. It handles pressures up to 750 psi and is built from ductile iron with an NBR seal.

What are the specifications of the GRUVLOK rigid coupling 390213454?

The GRUVLOK rigid coupling model 390213454 is a 2 in x 2 in rigid bolted clamp made of ductile iron with an NBR seal. It has a maximum operating pressure of 750 psi and is designed for grooved pipe connections 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 390213454 to customers across multiple industries.

How to install a GRUVLOK rigid coupling?

To install a GRUVLOK rigid coupling, ensure pipe ends are clean and grooved per manufacturer specs. Lubricate the NBR gasket, place it over the pipe ends, then position the ductile iron housing halves and tighten the bolts evenly to the recommended torque for a leak-resistant joint.
