RS107

  • O-Ring supported symmetrical rod seal.

  • For simple applications and universal use.

  • Not recommended for new designs.

  • Asymmetrical profile like RS103 is preferable.

Material and Application Parameters

²Pressure Values as a function of the hap 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.
Sealing Element Temperature (°C) Max. Sliding Speed (m/s) Maximum Pressure²
HPU Premium -30 - +100 0.5 400 bar (5800psi)
HPU Diet -20 - +100 0.5 400 bar (5800psi)
SLPU -20 - +100 0.7 400 bar (5800psi)
HPU Low Temperature -50 - +110 0.5 400 bar (5800psi)

Standard Dimensions

¹The specified extrusion gap is valid up to 70°C, higher temperatures requre lower values.
