Frequently Asked Questions

What is a GRUVLOK grooved pipe flange used for?

A GRUVLOK grooved pipe flange connects pipes in fire protection, HVAC, and industrial piping systems. Its ductile iron body and EPDM seal handle pressures up to 300 psi, providing a reliable, leak-resistant joint for water, air, or other compatible fluids.

What are the specifications of the GRUVLOK 0390201044 flange?

The GRUVLOK 0390201044 is a 3-inch grooved pipe flange made of ductile iron with an EPDM seal. It has a maximum operating pressure of 300 psi and an overall length of 10 1/2 inches. This genuine GRUVLOK component is designed for grooved-end pipe connections.

Where to buy GRUVLOK pipe flanges worldwide?

3G Electric supplies genuine GRUVLOK pipe flanges worldwide. We handle full logistics, customs clearance, and delivery to your site. As a global industrial solutions provider, we interpret your demand and source the right component — including this 3-inch ductile iron flange — for your application.

How to install a GRUVLOK grooved pipe flange?

Installation requires aligning the flange with a grooved pipe end, lubricating the EPDM gasket, and tightening bolts evenly to the manufacturer's torque specification. Always verify pipe alignment and pressure rating — here 300 psi — before pressurizing the system. Consult GRUVLOK's installation manual for exact procedures.
