Z-Split Kopper seals are thermoplastic piston seals designed with a Z-shaped split profile, allowing installation without removing the piston from the rod. This makes them particularly suitable for maintenance, retrofit, and on-site repair applications where full cylinder disassembly is not practical.
The thermoplastic material provides good wear resistance, dimensional stability, and low friction characteristics, while the split design enables controlled compression once installed in the groove. Z-Split Koppers are commonly used in hydraulic piston applications where ease of installation and reliable sealing performance are required.
