1.248 x 1.49 x 0.187FKM Rod T-Seal w/2 Molly/Nylon Back Ups Inch

Rod 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.
2. Spiral or twisting failure due to instability in the groove.
T-seal 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.
Temperature: -40°F to +225°F.
Pressure: 0 to 5,000 PSI
