HYMAX GRIP®  easily and reliably joins and restrains a wide selection of pipes of different types and diameters. Due to its patented design, it allows the joining of pipes made of the same or different materials and with the same or different diameters with unmatched ease.

This market-leading restraint coupling family, invented and manufactured by Krausz, features a unique radial gripping system suitable for both metal and plastic pipes, combining a top-facing two-bolt grip coupling that enables quick and easy installation. The HYMAX GRIP’s patented gasket effectively transforms the pipe joint into a flexible connection and allows dynamic deflection of the pipe of up to 4 degrees per side, reducing future pipe cracks and breaks. The GRIP is made of highly durable ductile iron, and withstands working temperature of up to +125°F, truly the perfect product for a fast and reliable restrained connection. HYMAX GRIP meets or exceeds standards AWWA C219, NSF-61 and NSF-372.

Krausz keeps a high level of inventory in several sites across North America in order to offer short lead times and support customers in emergency pipe repair situations. Per customers’ requests, we design custom-made products including extra-wide sizes, that provide quality solutions for pipe repair, join and restrain applications, using diverse products and superior quality raw materials.

PRECAUTIONS FOR HDPE PIPE:  Note that the use of pipe stiffeners is needed when you use the HYMAX GRIP on HDPE pipe.
