PNY Rod Seal – Heavy-Duty High-Pressure Hydraulic Rod Seal with Y-Ring Profile and Anti-Extrusion Design.
PNY heavy-duty rod seal with Y-ring profile and anti-extrusion design for high-pressure hydraulics. Bidirectional, low friction, durable. PU, –35°C~110°C, ≤45 MPa.
PNY Rod Seal – A rugged high-pressure hydraulic rod seal engineered for heavy-duty double-acting cylinder applications requiring reliable bidirectional sealing and extrusion protection. This Y-ring rod seal features an asymmetric lip geometry that delivers positive sealing under high-pressure and high-cycle conditions, while the pressure-energized lip design ensures tighter sealing as system pressure increases. The reinforced heel design resists pressure-induced deformation and prevents extrusion into radial clearances, making this heavy-duty rod seal ideal for demanding applications in construction, mining, and heavy equipment. The optimized lip contact minimizes friction, heat generation, and stick-slip for extended service life. Material: high-modulus polyurethane with excellent abrasion resistance. Temp: –35°C to +110°C. Pressure: up to 45 MPa. Speed: up to 2.5 m/s.
