Piston Ring Manufacturer - Custom Piston Rings & Seals

Piston Rings

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
piston rings Angle Cut / Butt Cut Piston Ring The angle cut is the most economical where high to moderate leakage across the piston is acceptable. RFQ
piston rings 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
piston ring seals Hook Joint Piston Ring The hook joint provides a latching of the piston ring to facilitate installation of the piston ring. RFQ
