SEAL K21
SEAL MA25

The K21/MA25 seal is designed for sealing pistons and piston rods.
Application: hydraulics, for reciprocating motion.
Material: high-resistance POLYURETHANE
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/MA25 seal is its versatility — it can be used for sealing both pistons and piston rods.
