U-Cup Back-Up Rings

Style 790 Back-up Rings feature exceptional strength and abrasion resistance compound HT-55OR (Orange) which makes them suitable for high pressure service where extrusion is a problem. Primarily used as a u-seal back-up, these rings can be used with o-rings. They also retrofit urethane and PTFE back-up rings, with greater performance characteristics.
