ElastoFlex™ Piston Seal

A single acting PolyFluor™ U-shaped seal with an O-Ring utilized as an elastic spring. It has low friction, no stick-slip effect, and is wear-resistant. It is used for pistons subjected to dynamic and static loads. Two ElastoFlex Piston seals, installed in separate grooves, heel to heel, are required for use on a piston.

ElastoFlex™ Piston seals are available in most PolyFluor™ materials and the O-Ring element is available in a wide variety of elastomeric materials.

Operating Ranges:

  • Speed: Reciprocating motion up to approximately 49ft/s (15 m/s)
  • Temperature: Approximately -65°F to +392°F (-60°C to +200°C), depending on the O-Ring compound
  • Dynamic Pressure: Up to 8,700 PSI (60 MPa)
