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
