Product Description

The GRUVLOK Bolted Clamp Coupling is a grooved pipe coupling for 5 in x 4 in pipe sizes, constructed of ductile iron with an EPDM seal and rated to 500 psi maximum operating pressure. It has an overall length of 10 5/8 in (MPN 0390009488).

Frequently Asked Questions

What is a GRUVLOK bolted clamp coupling used for?

A GRUVLOK bolted clamp coupling joins grooved-end pipes in fire protection, HVAC, and industrial piping systems. It provides a flexible, leak-tight connection rated to 500 psi, accommodating thermal expansion and misalignment in ductile iron or steel pipe runs.

What are the specifications of the GRUVLOK 0390009488 coupling?

This GRUVLOK coupling fits 5 in x 4 in pipe sizes, is made of ductile iron with an EPDM seal, and has a maximum operating pressure of 500 psi. Overall length is 10 5/8 in. It is a bolted clamp type for grooved pipe connections.

Where to buy GRUVLOK couplings worldwide?

3G Electric supplies GRUVLOK couplings worldwide, handling full logistics and customs clearance. As a global industrial sourcing partner, we provide genuine GRUVLOK parts like the 0390009488 bolted clamp coupling to any destination. Contact us for a quote and delivery options.

How to install a GRUVLOK bolted clamp coupling?

Installation requires clean, properly grooved pipe ends. Lubricate the EPDM gasket, place it over one pipe end, then slide the coupling housing over both ends. Tighten bolts evenly to the torque specified by GRUVLOK, ensuring the gasket is fully compressed for a 500 psi rated seal.
