The Parker Prädifa PDF cylinder seals profiles G5 and G6 are elastomer U-rings that due to their symmetrical shape and their pointed sealing lips need a support ring. These strikes can be made from all metal according to the information in this prospectus included drawing with dimension listor made of rubber. Round cords and standardized rings are suitable as rubber support rings. Plastic support rings are also possible.
Parker Praedifa Profiles G5 and G6 have a rectangular cross-section. In contrast to the G5 profile, the G6 profile has thicker sealing lips and therefore brushes the oil. When the engine is depressurized they extend even more intensely. These profiles are mainly called cylinder seals. It is also possible to use them to seal piston lengths. ln this case, however, no plastic support ring can be used. The profile G6 can also be provided with an outwardly sloping connection. Therefore they usually do not have a support ring, because the sealing edge is below the total height.
Scope of application:
Operating pressure: ≤ 160 bar hydraulic ≤16 bar pneumatics
operating temperature: -30 to + 100 C hydraulic -30 to + 80o C pneumatic
speed: = 1.0 m/s pneumatics
Mainly for the most diverse devices in hydraulics and pneumatics, here only in connection with maintained compressed air.
Installation instructions:
The tolerance for the groove stitch should be h9
so that the sealing lip is sufficiently prevented from tension.
It would also be valued when very little friction is placed. The grooves for the cylinder seal can be made with the bottom so that the pressure against the cylinder wall is reduced. this applies only for pneumatic devices. In hydraulics, on the other hand, they are specified dimensions and tolerances.
