MIL-PRF-87257B - Aircraft and Missile Low Temperature Synthetic Hydrocarbon Base Fire Resistant Hydraulic Fluid

We perform lubricants testing by military specification MIL-PRF-87257, which covers a synthetic hydrocarbon base hydraulic fluid used in aircraft automatic pilots and other hydraulic systems. This military specification describes the characteristics and provides the requirements for a synthetic hydrocarbon base hydraulic fluid used in the -54C to +200C temperature range in aircraft automatic pilots, shock absorbers, brakes, flap-control mechanisms, missile hydraulic servo-controlled systems, and other hydraulic systems using synthetic sealing material. This hydraulic fluid is identified by NATO Code No. H-538.
