Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.

Hydraulic seals

As a leading hydraulic seal manufacturer, we specialize in crafting high-performance hydraulic seals and hydraulic oil seals designed specifically for the hydraulic systems of engineering machinery and heavy equipment. Our seals utilize premium materials such as PTFE, PU, NBR, and FKM, boasting exceptional pressure resistance and wear durability. These seals can withstand up to 40MPa of working pressure and piston speeds of 1m/s, while operating efficiently within a temperature range of -20°C to 150°C, ensuring the hydraulic system runs smoothly and efficiently. They are widely applicable in hydraulic cylinders, pneumatic actuators, and other equipment.

 

Notably, our PTFE composite hydraulic seals, designed for heavy-duty applications, exhibit a 30% increase in wear resistance and can endure pressures up to 50MPa. They are ideally suited for hydraulic cylinder seals in excavators, injection molding machines, and other heavy equipment, significantly reducing maintenance requirements and lowering operational costs.
