From Mechanical/Industrial, plumbing and mining to energy and fire protection, Gruvlok® grooved products are designed to withstand the most rugged applications while providing durable and easy installation, and ultimately, saving time and money on any project requiring grooved over weld.

Through a combination of roll-grooving and two-bolt coupling design, Anvil’s innovative product line joins piping and other components into a single rugged yet flexible system. This makes Gruvlok products ideal for a variety of applications — particularly in tight spaces.


With a Gruvlok union at every joint, maintenance is as simple and flexible as the installation. Every component in a Gruvlok system is easily accessed and replaceable, so that you can make repairs without resorting to total shut-down.
