PK002 is a (natural) high-performance thermoplastic commonly referred to as PEEK. The material has excellent physical and chemical properties to serve a wide range of applications at high temperature. PK002 has good tribological characteristics and is recommended for precision parts, where tight tolerances are required. JST chose its PK002: Virgin PEEK for the back-up ring material. PEEK is a much...

Backup rings play a vital role in preserving the integrity of seals within pressurized aerospace hydraulic systems, minimizing leakage, and extending the lifespan of the components they protect. What are Backup Rings? The back up ring material could be PEEK, modified PTFE. PEEK™ back-up rings are designed to prevent extrusion in elastomer O-ring sealing systems. These rings are designed to close o...
