OUY Piston Seal – Double-Acting Hydraulic Piston Seal with O-Ring Energizer and Y-Ring Lip Profile
High-performance OUY piston seal for hydraulic cylinders. Double-acting, O-ring energized, low-friction, with Y-ring lip geometry. PU + NBR O-ring, –35°C~110°C, ≤40 MPa.
OUY Piston Seal – A premium hydraulic piston seal engineered for double-acting cylinder applications requiring reliable bidirectional sealing. This O-ring energized piston seal combines an NBR/FKM O-ring actuator that provides uniform radial loading to the Y-ring inspired sealing lip, ensuring consistent sealing performance across varying pressures, temperatures, and wear conditions. The asymmetric lip profile delivers positive sealing in both stroke directions with minimal leakage, while the low-friction polyurethane compound reduces heat generation and extends service life. The O-ring energizer compensates for wear, thermal cycling, and system pressure fluctuations, maintaining seal integrity over extended operating periods. This heavy-duty piston seal is ideal for mobile equipment, industrial machinery, and high-cycle hydraulic actuators. Material: high-grade polyurethane sealing element with NBR/FKM O-ring. Temp: –35°C to +110°C. Pressure: up to 40 MPa. Speed: up to 3 m/s.
