A PTFE/PEEK ring is mainly applied in the automotive transmission (AT) or continuously variable transmission (CVT) to maintain the oil pressure of the rotating or reciprocating components.

The PTFE ring can also be applied to an electric scroll compressor, and its good wear resistance and self-lubricating properties enable efficient sealing of the vortex disk.

PTFE and PEEK are materials designed to meet extreme temperatures, high pressure and high velocity working environments.

NOK-Freudenberg can provide different designs for PTFE/PEEK rings with different cross-section shapes or scarf-cuts to meet customer demands.
