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 start up leakage performance
- Extremely low friction
- Ability to adjust to cylinder concentricity
|Angle Cut / Butt Cut Piston Ring||The angle cut is the most economical where high to moderate leakage across the piston is acceptable.||RFQ|
|Step Cut Piston Ring||The step cut piston ring improves leakage control over an angle cut piston or butt cut. The step restricts a direct leakage path found in the butt cut design.||RFQ|
|Hook Joint Piston Ring||The hook joint provides a latching of the piston ring to facilitate installation of the piston ring.||RFQ|
