PPY Rotary Seal – Medium to High-Pressure Hydraulic Swivel Joint Seal with Y-Ring Profile.
PPY rotary seal for hydraulic swivel joints and rotating unions. Y-ring profile, low friction, leak-free rotation. PU/NBR, –35°C~100°C, ≤35 MPa, ≤1.5 m/s.
PPY Rotary Seal – A precision-engineered hydraulic swivel joint seal designed for rotary distributors, rotating unions, and continuous rotation hydraulic systems. This Y-ring rotary seal features an optimized lip geometry that ensures positive sealing under dynamic rotation and static dwell conditions while minimizing friction torque and heat generation. The Y-ring inspired profile provides reliable sealing across a wide pressure range, maintaining leak-free performance even under pressure fluctuations. The wear-resistant polyurethane or NBR compound delivers excellent resistance to abrasion, extrusion, and fluid degradation, ensuring long service life in demanding rotation applications. The compact cross-section fits standard swivel joint groove configurations. This rotary sealing solution is ideal for construction machinery, agricultural equipment, and industrial rotating unions. Material: high-grade polyurethane or NBR. Temp: –35°C to +100°C. Pressure: up to 35 MPa. Speed: up to 1.5 m/s.
