PS-SEAL® PTFE Rotating Shaft Seals

PS-SEAL PTFE rotating shaft seals excel under high pressure and in extreme vacuum.

PS-SEAL PTFE Rotating Shaft Seals give you best-in-class sealing performance for a wide range of high-speed and extreme pressure conditions.

Where others fail, PS-SEALs reliably seal rotating shafts at high circumferential speeds, high pressures, and extreme temperatures. PS-SEAL's excellent chemical resistance makes it well suited for food and pharma applications, including those where FDA approval is required.

Available in a wide variety of standard or custom styles and materials, the PS-SEAL utilizes high-performance GYLON® modified PTFE to maintain contact between the seal and shaft. The result is a seal that can withstand pressures up to 50 times that of standard lip seals, surface speeds up to 45 m/s, and temperatures up to 500º F (260ºC), in both dry and abrasive environments.

The portfolio of Garlock PS-SEALs includes standard, non-standard, and special customized seals.
