Oil Resistant Rubber Cup Seal for Hydraulic & Pneumatic Cylinders, High Sealing Performance

Our rubber cup seal (cup washer) is specially designed for hydraulic cylinders, pneumatic cylinders, shock absorbers and other equipment, providing excellent sealing performance. Made of oil-resistant, wear-resistant and pressure-resistant rubber materials, it can effectively prevent the leakage of hydraulic oil, gas and other media, ensuring the stable operation of the equipment. The cup seal has a reasonable structure, good elasticity and resilience, and can adapt to the reciprocating movement of the cylinder piston, with low friction and long service life. It is widely used in automotive, engineering machinery, hydraulic equipment, pneumatic equipment and other fields. We offer various specifications and models, and can customize according to your drawings and technical requirements. Bulk supply and OEM services are available.
