Field of application:

Working pressure: ≤ 500 bar
Working temperature: HFA-, HFB- and HFC-fluids: + 5 to + 60 °C Mineral oil:—20 to +100 °C

Surface speed: ≤ 0,5 m/s
Double-acting rod seal for piston rods and
dies. Also suitable for application in industrial and ”water hydraulics”.

Installation:

The design of the Prädifa rod sealing set profile ZG allows simple snap-in installation into closed housing. To avoid damaging care should be taken that the seals are not pulled over sharp edges during installation.

Compounds:

The standard compound for the Parker Praedifa sealing part is an NBR-based elastomer with a fabric-reinforced dynamic surface (SFR2′-compound Z5017). The back-up rings are made of a polyacetal-based (WE 5001)
material.
