UB-P Hytrel U-Seal Back-Up Rings offer superior strength and abrasion resistance, making them ideal for high-pressure applications prone to extrusion. Made from 55 Shore D Hytrel, these rings serve as reliable back-ups for U-seals and can be used with NU homogenous nitrile U-cups or O-rings when needed. They also serve as a durable alternative to urethane and, in some cases, PTFE back-up rings, fitting the same groove dimensions.
