High Quality Hydraulic Cylinder PU Rod Packing Oil Seals

Reliable Performance in Demanding Hydraulic Applications

Our high quality hydraulic cylinder PU rod packing oil seals are expertly engineered to provide unmatched performance in high-pressure hydraulic environments. Designed with precision and crafted from durable polyurethane (PU), these rod packing oil seals ensure a tight, leak-proof seal in single-acting and double-acting hydraulic cylinders. Whether used in heavy machinery, industrial equipment, or agricultural vehicles, these seals are built to resist deformation, wear, and pressure fluctuations, offering long-lasting protection against oil leakage and fluid contamination. With superior resistance to abrasion and extrusion, they deliver consistent performance in even the harshest conditions.

Product Specifications

Accurate Sizing and Secure Fit

Proper sizing is vital in hydraulic systems, and our seals are manufactured to strict dimensional tolerances for a flawless fit. These rod packing oil seals are tailored to meet exact specifications for hydraulic rods and glands, eliminating the risk of fluid bypass, pressure drop, and premature seal failure. Their precise fit reduces installation time and ensures smooth operation, preventing costly downtime and system malfunctions. These seals are a dependable choice for operators who require consistency, safety, and efficiency in hydraulic motion control systems.

Exceptional Material Strength and Heat Resistance

Made from premium polyurethane, our single lip oil seal offers extraordinary tensile strength and elongation, outperforming traditional rubber materials. This advanced PU formulation allows the seal to withstand continuous high pressure and heat exposure without cracking or hardening. It maintains flexibility even in cold conditions and performs exceptionally in high-temperature environments where thermal cycling is a concern. In addition to thermal durability, these seals are highly resistant to hydraulic oils, greases, water, ozone, and harsh chemicals—making them ideal for long-term use in industrial and mobile hydraulic applications.

Versatile Applications Across Industries

These PU rod packing oil seals are suitable for a wide range of sectors including manufacturing, construction, mining, marine, and automotive industries. They are commonly used in hydraulic cylinders, pistons, presses, lifting machinery, loaders, and excavators. Thanks to their single lip design, they offer low friction and smooth rod movement, extending the life of both the seal and the cylinder. Their excellent sealing capabilities ensure operational safety and performance consistency in both low-speed and high-speed hydraulic systems.
