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
