Polyurethane (PU) rod seals are mainly sealing elements made of polyurethane, used to prevent liquid or gas from leaking to the outside. Because polyurethane materials have good elasticity and mechanical properties, they have excellent sealing capabilities and are suitable for frequent reciprocating motion.
PU rod seals are commonly used in industrial fields such as engineering machinery, petroleum equipment, and agricultural machinery.
UHS seal and UNS seal are made of polyurethane (PU). Their design cross-section is a Y-shaped lip seal with the same height as the inner and outer sealing lips.
MPA pu rod seal is an asymmetric u cup rod seal with an outer diameter that tightly fits the indentation of the inner lip, and has good residual oil withdrawal capabilities.
Advantages of TYS PU Rod Seals
Excellent rebound performance, maintaining excellent sealing ability even in harsh environments
High wear resistance and low friction, extending service life and improving equipment operation efficiency
Oil resistance and corrosion resistance, resisting corrosion from chemical media such as hydraulic oil
Pressure resistance, able to withstand stable operation under high-pressure conditions, up to 40Mpa
