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.

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.
