At ACE14 in June, Hymax announced the launch of its new restraint coupling, the HYMAX GRIP.

The product comes as a restraint coupling or restraint flange adaptor, and features patented technology using universal teeth to restrain all types of connecting plastic and metal pipes. As water pressure is applied to the connecting pipes, the HYMAX GRIP increases its hold on the pipe.

“The HYMAX GRIP helps ensure pipes stay securely connected under extreme conditions, such as those caused by weather changes,” said Hymax USA president Tom Gwynn. “The HYMAX GRIP is based on the game-changing HYMAX technology that has been field proven in more than one million installations in the U.S. and Canada.”

Like the HYMAX, the HYMAX GRIP has a unique hydraulic sealing that allows joining pipes to move up to four degrees on each end of the coupling and still maintain a tight, durable seal. Through this ability of dynamic deflection the HYMAX GRIP absorbs a wide variety of fluctuating stresses, making it a durable and secure coupling that lasts.

Ready to use out of the box, the HYMAX GRIP restraint coupling and flange adapter both come with a pipe diameter range of 4 to 12 inches. It has a stab-fit design with a top-facing 2-bolt closure for the coupling and 1-bolt closure for the flange adaptor version. These features make it simple for installers to connect pipes and complete jobs quickly.
