Parker BS type rod seals

  BS type ULTRATHAN ® rod seal is a lip seal and prescribe at the outer diameter of the tight fit of the lip seal. Because additional lubricant between two lips, it greatly prevents dry friction and wear. In some cases, this seal can even replace expensive tandem seal configuration using two.

  For multi-stage cylinder applications, it is recommended to use cross-sectional dimensions of 4mm or 5mm specifications.

The main advantages are:

● excellent wear resistance.

● impact resistance, anti-extrusion.

● compression deformation.

● adapted to the most demanding working conditions.

● due to the pressure of the sealing lip between the media having charge

  Lubrication points.

● improve the sealing performance under zero pressure.

● Excellent preventing the outside air from entering.

● Easy to install.
