Product Description

The GRUVLOK Clamp Coupling is a rigid bolted grooved pipe coupling in a 5 in x 5 in size, constructed from ductile iron with an NBR seal. It has a maximum operating pressure of 750 psi and an overall length of 10 in (MPN 0390013704).

Frequently Asked Questions

What is a GRUVLOK rigid bolted clamp coupling used for?

A GRUVLOK rigid bolted clamp coupling joins grooved-end pipe in fire protection, HVAC, and industrial piping systems. It provides a leak-tight, rigid connection that resists axial movement, making it suitable for high-pressure applications up to 750 psi.

What are the specifications of the GRUVLOK 0390013704 coupling?

The GRUVLOK 0390013704 is a 5 in x 5 in rigid bolted clamp coupling made of ductile iron with an NBR seal. It has a maximum operating pressure of 750 psi and an overall length of 10 in. It is designed for grooved-end pipe in industrial systems.

Where to buy GRUVLOK clamp couplings worldwide?
