Krausz USA launched the HYMAX GRIP end cap, which uses universal teeth to securely cap pipes for a wide range of diameters. As pressure is applied to the end of a plastic or metal pipe, the HYMAX GRIP end cap’s unique radial gripping system increases its hold.
Made of durable ductile iron, the patented GRIP chain offers 360-degree restraint around the pipe. As the pipe applies axial pressure, the GRIP chain increasingly tightens over the pipe, preventing pipe pullout. The HYMAX GRIP end cap is suitable for many pipe diameters, replacing the need to use a range of end caps with a range of diameters and thus reducing inventory costs and saving shelf space.
