Cuff 80x100x12 K21 NBR

SEAL K21
The K21 seal is designed for sealing pistons and piston rods.
Application: hydraulics, for reciprocating motion.
Material: NBR90 ShA
High sealing efficiency is achieved through radial pre-tension of the sealing lips and pressure activation from the hydraulic system. Sealing performance is fully maintained at low pressure as well as zero pressure. The advantage of the K21 seal is its versatility — it can be used for sealing both pistons and piston rods.
