Hydraulic piston seals SPGA

The double-acting piston seal type SPGA byWYS is a specialized heavy duty piston sealing element, whose main function is to retain oil pressure. It consists of two components: an outer ring (slide ring) made of reinforced polyamide (PA, Nylon), and an inner ring with a circular cross-section made of nitrile rubber NBR 70 Shore A. The outer ring provides exceptional resistance to wear, deformation and extrusion in large clearances and has a specific cut to facilitate installation, while the inner O-ring provides constant radial compression and pressure maintenance.
