RS104R

The dimensions s + c are dependent on the respective seal type.

  • O-Ring and backup supported asymmetrical rod seal.

  • Suitable for large extrusion gaps and for higher pressure ranges.

  • Excellent sealing effect due to the design.

  • Standard design with rectangular backup ring.

Material and Application Parameters

²Pressure Values as a function of the hap dimension. ³≤Ø280mm: POM ; >Ø280mm: PA6G 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.
