Hao Seal manufactures custom hydraulic seals and pneumatic seals for cylinders, valves and fluid-power equipment. Our products include hydraulic cylinder seals, hydraulic rod seals, hydraulic piston seals, U-cup seals, wiper seals and hydraulic O-rings.
Send us your drawing, dimensions or operating conditions for material selection, seal design and quotation.
Hydraulic Seals for Demanding Industrial Applications
Hydraulic sealing systems operate under high pressure, continuous reciprocating motion, changing temperatures and demanding surface conditions. Reliable hydraulic cylinder seals help prevent fluid leakage, maintain system pressure and protect rods, pistons and cylinder surfaces from contamination and premature wear.
Hao Seal supplies hydraulic rod seals, piston seals, U-cup seals, wiper seals, buffer seals and high-pressure hydraulic seals for presses, lifting equipment, mobile machinery, steel processing equipment and other industrial hydraulic systems. Seal profiles and materials are selected according to pressure, speed, stroke, hydraulic fluid, temperature, groove design and surface condition.
Custom Hydraulic Seals and O-Rings for Your Equipment
As a hydraulic seal manufacturer and supplier, Hao Seal supports custom designs from sample development and prototyping to repeat production. Our hydraulic sealing components include hydraulic O-rings, polyurethane hydraulic seals, U-cup seals, rod seals, piston seals, wiper seals, gland seals and custom molded rubber parts.
Materials, profiles and dimensions can be customized for oil resistance, wear resistance, high-pressure operation, extrusion gaps and limited installation space. Send us your drawing, sample, groove dimensions or operating conditions for seal selection, material recommendations and quotation.
Custom Seals for High-Pressure Hydraulic Cylinders
Large-diameter hydraulic cylinders, presses and ram systems place heavy loads on rod, piston and gland sealing positions. Pressure spikes, extrusion gaps, side loads and contamination can cause leakage, rapid wear or seal failure when the seal profile or material is not properly matched to the application.
Hao Seal manufactures high-pressure hydraulic seals for standard and custom equipment, including hydraulic ram seals, hydraulic press seals, hydraulic cylinder piston seals, U-cup seals, wiper seals, gland seals and high-pressure hydraulic O-rings. Metric hydraulic seals and custom sizes are available in NBR, HNBR, FKM and polyurethane for different pressure, temperature, speed and hydraulic fluid conditions.
Send us your drawing, sample, rod and bore dimensions, groove size or operating conditions. We can recommend suitable materials and seal profiles for new equipment, replacement projects and custom hydraulic sealing requirements.
