Garlock PS-SEAL® PTFE Rotating Shaft Seals
Garlock’s PS-SEAL® PTFE Rotating Shaft Seals are engineered to deliver unparalleled sealing performance across a broad spectrum of high-speed and extreme pressure conditions. Unlike conventional seals, PS-SEALs demonstrate exceptional reliability in sealing rotating shafts, even under dry running, non-lubricated conditions at high circumferential speeds, intense pressures, and extreme temperatures.
The superior chemical resistance of the PS-SEAL makes it an ideal choice for applications in the food and pharmaceutical industries, including those requiring FDA compliance. The PS-SEAL leverages the robustness of high-performance GYLON® modified PTFE to ensure sustained contact between the seal and the shaft. This unique design enables the seal to endure pressures up to 50 times greater than standard lip seals, surface speeds reaching 45 m/s, and temperatures as high as 500º F (260ºC), making it effective in dry and abrasive environments. Garlock’s PS-SEAL portfolio is comprehensive, encompassing standard, non-standard, and specially customized seals for diverse specifications, with no minimum quantity requirements and industry-best lead times.
