Update:2017-02-19

Polyurethane oil seals mainly used in hydraulic cylinder, easily to install and scrape the dust adhered on the piston rod. The Polyurethane oil seals in green color hardness is a bit lower, and the Polyurethane oil seals in blue color hardness is higher, so it can withstand the higher pressure.

Polyurethane oil seals has good good mechanical performance, abrasion resistance and oil resistance, suitable for harsh working conditions, prevent the dust or external impurities entering, so as to achieve excellent sealing performance, commonly used in medium high pressure hydraulic cylinder.
