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.
