SynLube™ supplied
hydraulic fluid (HF) which is similar to our PSF (Power Steering
Fluid) is used by NASA
in the Landing Gear System in every Space Shuttle Flight.
SynLube™ has been
chosen because of its wide operating temperature range (-70 F to 700 F) high viscosity
index (VI=220) and universal compatibility with the seals and materials used in the
Landing Gear System components.

Orbiting in Space the HF fluid reaches -30 F to -40F

30 minutes before landing the ceramic tile covered bottom is red hot and the HF fluid
reaches 375 F to 425 F

Minutes before landing the Landing Gear mechanism powered by the HF which is still at over
275 F must operate reliably, as there is only ONE chance for safe landing.
