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™ Piston Seals are available in most materials- except silicone and fluorosilicone. UltraMod™ PolyTee™ Piston 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)
