PGY Piston Seal – Double-Acting Hydraulic Piston Seal with Y-Ring Profile for Bidirectional Cylinders.
PGY double-acting piston seal with Y-ring profile for bidirectional hydraulic cylinders. Low friction, pressure-responsive, reliable. PU, –35°C~110°C, ≤40 MPa, ≤3 m/s.
PGY Piston Seal – A high-performance hydraulic piston seal engineered for double-acting cylinders requiring reliable bidirectional sealing and pressure-activated performance. This double-acting piston seal features a Y-ring inspired lip geometry that provides positive sealing in both stroke directions with minimal leakage. The pressure-energized lip design ensures tighter sealing as system pressure increases, while the symmetrical profile delivers balanced performance under pressure reversal and varying operating conditions. The optimized lip contact reduces friction and wear while maintaining seal integrity, and the robust construction resists extrusion and deformation under cyclic loading. This Y-ring piston seal is ideal for medium to high-pressure hydraulic cylinders in mobile equipment, industrial machinery, and heavy-duty applications. Material: high-grade polyurethane. Temp: –35°C to +110°C. Pressure: up to 40 MPa. Speed: up to 3 m/s.
