NYH Rod Seal – Heavy-Duty High-Pressure Y-Ring Seal with Backup Rings

NYH Rod Seal – Heavy-Duty High-Pressure Hydraulic Rod Seal with Y-Ring Profile and Integrated Backup Rings.

NYH high-performance rod seal with Y-ring profile and integrated backup rings for extreme-pressure hydraulics. Bidirectional, anti-extrusion, durable. PU, –40°C~110°C, ≤45 MPa.

NYH Rod Seal – A rugged high-pressure hydraulic rod seal engineered for extreme-duty double-acting cylinder applications requiring reliable bidirectional sealing and maximum extrusion protection. This Y-ring rod seal features an asymmetric lip geometry that delivers positive sealing under extreme pressures and high-cycle conditions, while the pressure-energized lip design ensures tighter sealing as system pressure increases. The integrated anti-extrusion backup rings provide superior gap resistance under pressure spikes and shock loads, preventing extrusion into radial clearances. The optimized lip contour minimizes friction, heat generation, and stick-slip for extended service life. This heavy-duty rod seal is ideal for demanding applications in mining equipment, construction machinery, excavators, and heavy industrial hydraulics. Material: high-modulus polyurethane with wear-resistant backup rings. Temp: –40°C to +110°C. Pressure: up to 45 MPa. Speed: up to 2.5 m/s.
