Description
Product group: Piston seal
Design: K compact seal
Profile no.: 22
Specification: Z suitable for two-sided pressure load
Seal material: NBR fabric NBR F 90 3005
Seal body: NBR 80 3001
Guide rings: PA

Operational application limits
Pressure (MPa): ≤ 40
Temperature (°C): -30

Function
The KK 03 compact seal is a double-acting seal combined with back-up and guide elements. The KK 03 guarantees a good sealing function – also in low pressure areas. Due to the integrated guide elements, the piston length can be reduced to save material.
