RU9 Rod U-seal
Style RU9 seals are molded from MDI based Zurcon® Z25 urethane. This seal offers good elasticity with low compression set while maintaining a high level of tribological characteristics. The dynamic seal lip incorporates slide segments that will increase back-pumping capabilities while reducing friction. The RU9 style rod seal is ideal for hydraulic applications where high temperature and high pressure performance is required.
