PNY Rod Seal – A premium high-pressure hydraulic rod seal engineered for the most demanding double-acting cylinder applications. This heavy-duty rod seal combines a precision Y-ring lip profile with an advanced anti-extrusion heel design, delivering reliable bidirectional sealing under extreme pressures, high-cycle conditions, and severe shock loads.
The pressure-energized lip geometry ensures tighter sealing as system pressure rises, while the reinforced heel prevents extrusion into radial clearances — a common failure point in standard seals. This anti-extrusion rod seal significantly extends service life in construction, mining, and heavy equipment applications where unplanned downtime is costly.
Manufactured from high-modulus polyurethane, the PNY seal offers exceptional abrasion resistance, thermal stability, and resistance to hydraulic fluid degradation. The optimized lip contour minimizes friction, heat generation, and stick-slip, reducing operating temperatures and prolonging seal integrity. Whether used in excavator boom cylinders, mining haul truck suspension systems, or industrial press applications, this high-performance rod seal consistently delivers leak-free performance.
The PNY rod seal is trusted by OEMs and maintenance professionals worldwide for its durability, reliability, and cost-effectiveness. Available in a wide range of standard and custom sizes to fit your specific cylinder groove configurations. Backed by rigorous quality control and ISO-compliant manufacturing.
