Category:

The function of the Parker Prädifa ULTRATHAN© wiper rings profile A1 is to prevent dust, dirt, grains of sand and metal swarf from penetrating. This is achieved by a special design that largely prevents the development of chamfers, protects the guiding parts, and extends the working life of the seals. Oversized diameters ensure a tight fit in the groove thus preventing the penetration of foreign particles and dampness.

This Parker Praedifa wiper ring profile Al provides a technically accurate closure at the cylinder; no screwrings and brackets are required. No close tolerances are necessary and no metal inserts. The corrosion which may occur with metal-cased wipers will be prevented. For the groove close tolerances are not required. If minor quantities or other diameters are required, these may be cut from the next largest size having the same cross-section (for further instruction please refer to the passage “Installation”).

ULTRATHAW wiper rings profile Al are for axially operated rods in hydraulic
plungers and rodguidances.
