High Quality PU Piston Oil Seals for Hydraulic Cylinders

Precision Sealing Solutions for Hydraulic Cylinder Applications

Our PU Piston Oil Seals for Hydraulic Cylinders are engineered to deliver superior sealing performance under the demanding conditions of hydraulic systems. Made from high-quality polyurethane (PU), these seals are designed to withstand high pressures, resist wear and extrusion, and maintain consistent sealing effectiveness over prolonged periods. The advanced PU material offers excellent mechanical strength, elasticity, and chemical resistance—making it an ideal choice for dynamic sealing applications in hydraulic cylinders where precision and durability are paramount. Whether in mobile machinery, construction equipment, or agricultural hydraulics, these piston seals ensure smooth operation and minimal downtime.

Product Specifications

Tailored for Performance and Longevity

The robust design and composition of our PU piston oil seals provide outstanding resistance to hydraulic fluids, heat, and high pressure. This ensures minimal leakage, reduced wear, and maximum efficiency of the hydraulic system. PU offers an optimal combination of hardness and flexibility, which makes these seals effective in both low- and high-speed piston movements. Thanks to their reliable sealing ability, they extend the service life of equipment and reduce maintenance costs. These seals are particularly suited for heavy-duty environments where long operational cycles and harsh conditions are typical.

Ideal Fit for Hydraulic Cylinders

Every PU piston oil seal is manufactured with high dimensional accuracy to provide a perfect fit in standard and custom hydraulic cylinder assemblies. A precise fit ensures secure sealing, prevents fluid bypass, and enhances operational stability. The seals’ compatibility with standard cylinder grooves makes installation straightforward and reduces the need for costly customization. Whether you’re maintaining existing equipment or assembling new hydraulic systems, our PU seals provide the performance reliability you need for peace of mind in every application.

Compatible with Kubota and More

Our kubota oil seal offerings are suitable for various OEM specifications, including Kubota’s hydraulic machinery. These seals are ideal replacements in maintenance or OEM-equivalent applications. Their PU construction makes them ideal for agricultural and construction machinery where Kubota parts are widely used. With reliable performance and OEM-grade quality, these piston seals help preserve your equipment’s efficiency and durability in the field.

Extensive Industry Applications

These PU piston oil seals are used across a variety of sectors, including construction, agriculture, mining, industrial manufacturing, and transportation. They are especially beneficial in high-load, high-cycle applications that demand long-lasting performance. Whether you operate excavators, loaders, backhoes, or press machines, our seals will serve your operational needs reliably. Their resistance to abrasion, water, and oils makes them versatile for indoor and outdoor hydraulic systems alike.
