SPGW Piston Seal – Bidirectional Double-Acting Hydraulic Seal

SPGW Piston Seal – Double-Acting Bidirectional Hydraulic Piston Seal with Pressure-Activated Lip Geometry.

SPGW bidirectional piston seal for double-acting hydraulic cylinders. Pressure-activated, low-friction, groove-stable. PU, –35°C~110°C, ≤40 MPa, ≤3 m/s.

SPGW Piston Seal – A high-performance bidirectional piston seal engineered for double-acting hydraulic cylinders requiring reliable sealing in both stroke directions. This double-acting piston seal features an advanced pressure-activated lip geometry that ensures positive sealing as system pressure increases, delivering consistent performance across a wide pressure range. The optimized multi-lip configuration provides reliable bidirectional sealing with minimal leakage, while the low-friction polyurethane compound reduces wear, heat generation, and stick-slip for extended service life. The reinforced heel design resists pressure-induced deformation and maintains groove stability under cyclic loading, making this hydraulic piston seal ideal for medium to high-pressure applications in mobile and industrial equipment. Material: high-performance polyurethane. Temp: –35°C to +110°C. Pressure: up to 40 MPa. Speed: up to 3 m/s.
