TP0 - 3 PC NITRLIE PISTON T-SEAL w/NYLON BACKUPS- INCH

Piston T-seals were originally developed to replace O-rings, and retrofit into standard commercial O-ring grooves. This development ended two serious reliability problems: 1. Extrusion through the clearance gap, and, 2. Spiral or twisting failure due to instability in their groove. T-seals’ back-ups are hydraulically or pneumatically driven against the dynamic surface when system pressure forces the elastomer into the space beneath the back-up. This immediate response to pressure makes them very effective wipers, keeping contaminants away from the sealing line. Standard material for our T-seals is 75 durometer nitrile with moly-filled nylon back-up rings. Other materials are available upon request. Industrial piston T-seals are also available to fit one and two back-up O-ring grooves. Please refer to Wide Base T-seals in this section. Temperature: -40° to 225°F Pressure: 0 to 5,000 PSI
