Our U‑profiled seal provides excellent resistance to extrusion and abrasion in general duty hydraulic systems.
Lionsele U1 is a U-profiled seal of high performance polyurethane, that provides excellent resistance to extrusion and abrasion in general duty hydraulic systems. The combination of Lionsele U1's seal material and design minimises plant downtime - even in aggressive working environments.
The lip profile is designed as an interference fit within the housing. The radial squeeze provided by this action gives efficient sealing at low pressures. When pressure rises. the seal becomes pressure-responsive to maintain sealing forces throughout the operating range.
General duty systems
Suitable for use with most mineral-based hydraulic fluids at temperatures up to +100°C (+212°F). Also resistant to air and most lubricating oils and greases. Where fire-resistant fluids of the water/oil emulsion or water/glycol types are used, please contact us for advice on temperature limits.
Designed for use with heavy-duty hydraulic packings where conditions are particularly arduous.
Our compact rod/gland seal and single-acting piston seal with high and low pressure sealing capabilities.
Highly proven on industry's most arduous applications.
A compact rod / gland seal providing smooth operation and low levels of breakout and dynamic friction.
A rod and gland seal that operates reliably for long periods with the minimum thickness of fluid film on the dynamic contact surface.
A pressure-responsive hydraulic seal designed for arduous reciprocating gland applications.
