Product information 

The Parker Prädifa Park-O-Pak cylinder seal type S Profil SA is the further development of the nutringes and unites the Vodeih in itself of the highly elastic O-ring and the most abrasion-resistant grooved ring works. The special feature of this predominantly square Parker Praedifa seal is the embedded O-ring. This also works at low pressures and under vacuum (necessary for the sealing function)

This pre-tensioning force remains at a temperature influence largely constant, and independently with a certain amount of wear, this guarantees the necessary pressure performance. When the system pressure increases, this contact pressure by the pressure-dependent deformation of the O-ring accordingly reinforced.
