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.

Sanitary High-Pressure Clamps for hygienic gasket connections
In the pharmaceutical and food processing industries, down-time is highly undesirable. Sterilization cycles are carried out in the shortest possible time with high concentrations of the chemicals, high temperatures and increased flow rates.
To fulfill these requirements not only the gaskets have to provide an outstanding performance, also the clamp itself needs to maintain a uniform compression of the gasket at all times. As a result, contamination risks and the revolving need of retightening the connections can be prevented.
