AeroShell Landing Gear Fluid (LGF)


AeroShell Landing Gear Fluid (LGF) is a mineral hydraulic fluid (MIL-PRF-5606) to which additional additives have
been added to improve the extreme pressure characteristics and the fluid’s natural lubricity. The lubricity agent
provides a stable thin film layer to the metal surfaces at mild operating conditions. When severe conditions exist
(landing/ touchdown), the extreme pressure additive supplies the load carrying needed at the metal-to-metal surfaces to prevent the occurrence of such phenomena as “ladder cracking” and “slip stiction” of the piston component of the landing gear. AeroShell LGF is AeroShell Fluid 41 plus additives.

Main Applications


  • The excellent low temperature properties of AeroShell LGF make it particularly suitable in areas of low temperature operations.
  • AeroShell LGF is straw yellow in colour.
