A five‑piece, double‑acting seal with split anti‑extrusion and wear rings.
Lionsele SP is designed for use on spool type or single-piece pistons, and is also suitable for use on two-piece piston assemblies.
This seal comprises an elastomeric sealing element, two anti-extrusion rings and two rigid thermoplastic wear / guide rings.
The elastomeric sealing element has an interference fit with the housing to ensure sealing integrity even at low pressures. The anti-extrusion rings prevent extrusion of the sealing element at higher pressures, whereas the wear/guide rings act as bearings to align the piston within the cylinder bore.
Suitable for use with most mineral-based hydraulic fluids, and most fire-resistant fluids of the water/oil emulsion and water/glycol types, at temperatures up to +100°C (+212°F). Also resistant to air, water and most lubricating oils and greases.
