What is the difference between UN seal and USH seal?

1.The material for UN seal and USH seal is different, the UN piston and rod seal material is PU, the USH seal material is NBR.
2.UN hydraulic seal and USH seal have different pressure resistance. UN maximum pressure resistance is 30Mpa, while USH maximum pressure resistance is 14MPa, and the pressure resistance can reach 21MPa with retaining ring.
3. UN seal is mainly used for fluid media sealing, but the USH seal can used both for seal fluid and air.
