DESCRIPTION
POLYURETHANE O-RING | EXCELLENT WEAR-RESISTANT SEALING SOLUTION
Urethane O Ring (PU sealing ring) is a high-performance elastic seal specially designed for harsh working conditions. With extraordinary wear resistance (5-10 times that of ordinary rubber) and excellent mechanical strength, it has become an ideal sealing choice for heavy-duty hydraulic and pneumatic systems. Our polyurethane seals perfectly balance durability, oil resistance and cost-effectiveness.
