The PS-SEAL® PTFE Rotating Shaft Seal delivers best-in-class sealing performance for high-speed, high-pressure, vacuum, and extreme temperature applications where others fail. Available with Garlock’s proprietary GYLON® PTFE lip, it offers exceptional wear resistance, low friction, chemical compatibility, and full compliance with FDA, USP VI, EN 1935/2004, and ATEX standards, making it ideal for food, beverage, and pharmaceutical industries. With the ability to handle pressures up to 50 times that of standard lip seals and temperatures up to 500ºF (260°C), the PS-SEAL® thrives in both dry running and abrasive environments. Available in multiple lip configurations and fully customized designs, it’s the ultimate solution for demanding rotary shaft sealing needs.


PS-SEAL® is offered in a range of high-performance lip materials and configurations, allowing each seal to be optimized for abrasion resistance, dry-running capability, heat dissipation, or chemical compatibility. This flexibility extends service life, reduces downtime, and ensures reliable performance across demanding food, beverage, and pharmaceutical processes. With short lead times, no minimum order requirements, and engineering support for unique applications, PS-SEAL® provides a versatile and dependable solution for critical rotary shaft sealing challenges.

  • Overview

Features and Benefits:

  • Withstands high pressures, vacuum, and high shaft speeds for reliable sealing in demanding applications.
  • Maintains integrity through CIP and SIP cycles, reducing contamination risks and cleaning downtime.
  • Ships with short lead times, no minimum orders, and engineering support for custom designs.
  • PS-SEAL® with KF (carbon fiber) lip excels in dry-running service, extending life and reducing downtime.
  • PS-SEAL® with MS (molybdenum disulfide) lip resists abrasion in powders, slurries, and particulate media.
  • PS-SEAL® with GYLON® BLACK (graphite) lip provides reliable performance where consistent lubrication is present, ensuring durability and long service life.
  • PS-SEAL® with F (Econol) lip is optimized for vacuum service, ensuring tight sealing under low-pressure conditions.
  • PS-SEAL® with GYLON® WHITE (barium sulfate) lip ensures FDA and EN 1935 compliance for food and pharma processes.
  • PS-SEAL® with GYLON® BLUE (glass microsphere) lip offers flexibility and stability in dry-running or start-stop conditions.
