Product Description

The GRUVLOK 0390065320 Clamp Coupling is a 316 Stainless Steel grooved pipe coupling with a 12 in x 12 in fitting pipe size, 18 53/64 in length, EPDM gasket, and bolted connection rated for 750 psi maximum operating pressure. This rigid-movement-tolerance coupling (MPN 0390065320) is designed for secure, leak-free joining of grooved-end piping systems in demanding industrial applications.

Frequently Asked Questions

What is the GRUVLOK 0390065320 clamp coupling used for?

The GRUVLOK 0390065320 clamp coupling is used to join grooved-end piping in demanding industrial applications such as water, oil, and chemical systems. Its 316 stainless steel construction and EPDM gasket provide leak-free, rigid connections rated for 750 psi, making it suitable for high-pressure environments.

What are the specifications of the GRUVLOK 0390065320 coupling?

The GRUVLOK 0390065320 coupling has a 12 in x 12 in fitting pipe size, 18 53/64 in length, 316 stainless steel body, EPDM gasket, bolted connection, and a maximum operating pressure of 750 psi. It is a rigid-movement-tolerance coupling (MPN 0390065320) for secure grooved-pipe joints.

Where to buy the GRUVLOK 0390065320 coupling worldwide?

3G Electric supplies the GRUVLOK 0390065320 coupling worldwide, handling full logistics and customs clearance. As a global industrial solutions provider, we source and deliver this 316 stainless steel grooved coupling to your site, ensuring compliance with international shipping requirements.

How to install a GRUVLOK rigid clamp coupling?

To install a GRUVLOK rigid clamp coupling, align the grooved pipe ends, lubricate the EPDM gasket, and place it over the joint. Position the coupling housing over the gasket, insert bolts, and tighten evenly to the manufacturer's torque specification. Verify alignment and pressure rating before system pressurization.
