DAS compact seals are a double-acting sealing and guiding component consisting of an elastomeric sealing ring, two backup rings, and two guide rings. The das piston seal provides excellent sealing performance in both static and dynamic conditions, while the backup rings prevent extrusion of the rubber sealing ring.
Design Description:
The guide rings serve as effective support elements, and the unique structural design of the elastomeric component ensures distortion-free installation within the groove. The DAS seal hydraulic is a compact combination of sealing and guiding, suitable for installation in open or closed grooves, enabling applications in extremely tight spaces.
Materials:
Sealing Ring: Nitrile rubber (NBR)
Backup Rings: High-strength polyester elastomer
Guide Rings: Modified polyoxymethylene (POM)
