PORTSMOUTH, N.H., Oct. 31, 2012 (GLOBE NEWSWIRE) -- Anvil^® International, one of the largest and most complete manufacturers of pipe fittings, pipe hangers and piping support systems in the world, introduced its revolutionary SlideLOK™ rigid coupling September 24 at MINExpo INTERNATIONAL^® 2012 in Las Vegas.

SlideLOK's unique design allows for fast, easy and safe installation. The installer simply lubricates the exposed gasket surfaces and slides the coupling completely over the pipe end, where it securely remains until the installer adds the adjacent component and slides the coupling into place. An impact or socket wrench tightens the two bolts to finish the job.

SlideLOK features a patented coupling and pressure-responsive gasket with four separate sealing contacts that engage the groove 360 degrees around the pipe. A specially developed leading edge eliminates gasket pinching, and the gasket lips facilitate easy slide-over action. The pressure-responsive gasket uses technology unique to the industry and only available with the SlideLOK couplings.

"We believe SlideLOK will have a significant impact on the grooved piping industry," said Brandon Gunnell, marketing director at Anvil. "Once people see the superior design and safety in action, SlideLOK will be the obvious choice." Bill Vivlamore, president of Frontier Supply, agrees, stating "SlideLOK is the most advanced ready for installation coupling ever developed."

SlideLOK is the result of extensive research and development by Anvil. The development team also participated in thorough field testing to assess and perfect the coupling's performance prior to its release.

"We completed extensive research and testing before releasing SlideLOK," said Joe Radzik, vice president of R&D at Anvil. "Now our customers will have the opportunity to benefit from its technically superior design."
