GYLON® 3545 Tuff-Rail®

Revolutionary railcar manway gaskets

Manufactured from 100% pure PTFE and utilizing our proprietary GYLON® process, the 3545 TUFF-RAIL® gasket is specifically designed to help address those difficult installation and sealing requirements of manways. Formulated to compress and conform, the 3545 TUFF-RAIL® is easily installed with excellent load retention, maintaining a tight seal even during heavy vibration and thermal cycling. The patent pending technology incorporates raised ribs to insure the gasket performs under the limited bolt load and the narrow seating surface of the nozzle.
  • Manufactured with 100% pure PTFE for universal chemical resistance
  • Proprietary GYLON® 3545 and raised sealing ribs offer excellent creep resistance and long term bolt load retention
  • Highly compressible for low load sealing on less than ideal flange surfaces
  • Tough, reliable and reusable—ideal for heavy vibration, thermal cycling, and over-torqueing
  • Engineered to a single size to fit the most common manways simplifying inventory (AAR-1, UTC-1, TRN-1)
  • Unlimited shelf life and high crush resistance – issues commonly associated with rubber gaskets
  • The TUFF-RAIL® patent pending technology relies on unique materials & advanced design for superior performance
