Anvil® Introduces Two-Piece Large Diameter Gruvlok® Couplings

PORTSMOUTH, N.H. (April 11, 2011) — Anvil International, one of the largest and most complete manufacturers of pipe fittings, pipe hangers and piping support systems in the world, announced the introduction of two-piece large diameter standard groove couplings to its Gruvlok product line.

The new couplings will be available in both rigid and flexible styles and use standard grooves that conform to the American Water Works Association (AWWA) C606 standard for grooved and shouldered joints.

Most large diameter couplings on the market come in four pieces, making them difficult and time-consuming to install. A two-piece coupling offers substantial advantages for installers, especially for large jobs.

Large diameter couplings are typically heavy and often require special equipment. These new Gruvlok couplings require no special grooves, grooving tools, fittings or valves and use up to 23% less weight than competitive models.

“The Gruvlok line has always provided installers with high-quality products that are flexible and easy-to-install,” said Dean Taylor, Anvil’s vice president, sales and marketing. “The launch of these two-piece couplings is another example of Anvil’s commitment to meeting the wide-ranging needs of our users.”

Gruvlok two-piece large diameter couplings are rated for 350 P.S.I. on cut or roll grooved pipe and are available in sizes that range from 14" through 24".
