Rod PolyTee™ Seal Assembly

Has a unique geometry to prevent rolling and spiraling of the elastomer seal element. Traditionally this type of seal has been used primarily as a static seal, but it works well dynamically as the PolyMod® or UltraMod™ elastomer provides for both low friction and better wear life as compared to conventional T-Seals. PolyTee™ Seal Assemblies can be used in standard O-ring glands.

PolyMod® PolyTee™ Rod Seals are available in most materials- except silicone and fluorosilicone. UltraMod™ PolyTee™ Rod seals are available in fluoroelastomer compounds only.  The back-up ring elements are available in most PolyFluor™ and some PolyTel™ materials.

Operating Ranges:

  • Speed: Reciprocating motion up to approximately 4 ft/s (1.2 m/s)
  • Temperature: Approximately -65°F to +392°F (-54°C to +200°C), depending on the elastomer compound
  • Pressure: Can seal pressures up to 6,500 PSI (45 MPa)
