The Parker Prädifa PDF cylinder gasket profile EO is used in pneumatic and hydraulic development. Due to his lip design and low coefficient of friction, it can an be used as a hydraulic and as a Pneumatic seal. We deliver different options. Support rings or brackets are due to the special shape not mandatory. The exchange with the profiles C2 (pure hydraulic) and E (unlubricated compressed air) is possible through the same groove dimensions.

Scope of application:

Hydraulics:
Operating pressure: ≤ 100 bar
Operating temperature: – 25 to + 100 “C
Sliding speed: ≤ 0.5 m / s
Pneumatic: (oiled compressed air)
Operating pressure; ≤ 16 bar
Operating temperature: – 25 to + 80 “C
Sliding speed: ≤ 1 m / s
Particularly suitable for sealing of pistons in hydraulic and pneumatic cylinders.

Installation instructions:
The Parker Praedifa PDF cylinder seals Profile E6 are undersized in diameter compared to the nominal value. Only the sealing lip diameter is its nominal size. These PDF lip rings can easily be snapped into closed nubs. When installing is make sure that the seals are not being pulled over sharp edges. With double-acting pistons with pressure surges that are above allowable operating pressure need to be avoided. ln such cases sealing elements larger cross-sections or other PDF profiles with support rings can be used.

Material:
The standard material is an NBH elastomer with a hardness of approx. 88 Shore A
