PU1
The PU1 Piston Seal is a unidirectional polyurethane Piston Seal with knife trimmed sealing lips for enhanced sealing performance. Typically used in a single acting cylinder application or two seals back-to-back in separate seal glands.
This is recommended for light to medium duty hydraulic cylinder applications requiring low temperature and high pressure.
