Hymax 890-56-12322-16 - Hymax Grip Coupling - 12"

HYMAX GRIP joins and restrains a wide selection of pipes of different types and diameters, easily and reliably. Due to its patented design, it allows the joining of pipes of the same or different materials and diameters, and preventing axial pipe movement.

This market-leading restraint coupling family, invented and manufactured by Hymax, features a unique radial gripping system suitable for most metal and plastic pipes, combining a top-facing two-bolt grip coupling that enables quick and easy installation. The HYMAX GRIP's patented gasket 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 can withstand a 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.
