HDP 330
Design

    Two-part seal set for sealing pistons, consisting of a PA slide ring with a stepped cut and an elastomer contact pressure element for producing pre-load.

    • Extreme strength against gap extrusion thanks to the PA sliding component
    • Extremely high abrasion resistance
    • Stepped cut for easy fitting in a closed housing
    • Greater surface roughness partly permissible in comparison to conventional seals
    • Rectangular contact pressure element produces consistently high pre-loading force and offers high protection against twisting in the housing
    • Housings should preferably comply with ISO 7425-1
    • Dynamic and static tightness comparable to PTFE piston seals
Material

    Slide ring: Fibreglass filled modified polyamide

    Contact pressure element: Nitrile rubber NBR - 70 NBR 177605 - 70 Shore A
