Custom Piston Ring & Seal Manufacturer
Piston Rings seals made from Duron® PTFE materials are used for bi-directional piston sealing applications. This sealing system is used in high speed reciprocating applications such as non-lubricated compressors and cryogenic fluid pumping applications. There are three joints are commonly used in a Duron® PTFE piston ring.
Features & Benefits
- Easily passes over ports
- Available with a stainless steel spring to improve startup leakage performance
- Extremely low friction
- Ability to adjust to cylinder concentricity
