RS119

Technical drawing of a mechanical part showing various dimensions and features, including rounded and burr-free edges, with measurements for diameter, radius, length, and angles.

Spring supported asymmetrical PTFE rod seal.
For low friction and good dry running properties.
Excellent chemical and thermal resistance.
Application in the food, pharmaceutical and chemical industry.

Material and Application Parameters

  ²Pressure Values as a function of the gap dimension.
  The specified application parameters are generally valid values and must not be used simultaneously with the application.
  An order can be placed by specifying the profile type, material and specified housing design dimensions.
