Split Nylon backup ring with a flat cross-section.
Nylon Material | 4 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | Backup Ring
Features
- High strength and abrasion resistance
- Wide temperature range
- Chemical resistance
- Low friction
- Easy installation
Style 590 Back-up Rings feature exceptional strength and abrasion resistance along with a 53 Shore D hardness rating 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. “S” suffix designates a split ring.
