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
|Angle Cut / Butt Cut Piston Ring||
The angle cut is the most economical where high to moderate leakage across the piston is acceptable.
|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.
|Hook Joint Piston Ring||
The hook joint provides a latching of the piston ring to facilitate installation of the piston ring.
Piston ring seals are available in many different Duron® materials and are specified based on your conditions and parameters. For a complete proposal, submit a request for quote and we will respond, immediately.
