Frequently Asked Questions

What is a GRUVLOK metal pipe flange used for?

A GRUVLOK metal pipe flange connects grooved-end pipes in industrial fire-protection, HVAC, and process-piping systems. Its ductile-iron body and NBR seal handle up to 300 psi, making it suitable for water, oil, and chemical lines where quick mechanical assembly is needed.

What are the specifications of the GRUVLOK 3-inch pipe flange?

This GRUVLOK flange is 3 inches, ductile iron with an NBR seal, rated for 300 psi maximum operating pressure. Overall length is 10 1/2 inches. The manufacturer part number is 0390201549. It uses a grooved connection for fast, reliable joint assembly without welding.

Where to buy GRUVLOK pipe flanges worldwide?
