Product Description

Mineral oil-based, red-dyed aviation hydraulic fluid formulated for aircraft hydraulic systems where a MIL-PRF-5606A ashless, zinc-free fluid is required. It functions as an antiwear hydraulic medium for aerospace and industrial equipment operating across a wide temperature range in both pressurized and non-pressurized systems.

0 1. Overview

This hydraulic fluid is part of a high viscosity index ashless formulation that uses a mineral oil base with no zinc or other heavy metals in its additive package. It is formulated with antiwear chemistry for hydraulic pumps and motors and includes protection against rust and corrosion on hydraulic system components. The fluid is resistant to oxidation, reducing deposit formation and limiting viscosity increase in service, and it also provides resistance to excessive foam buildup that would otherwise degrade hydraulic response.

The product is identified as MIL-PRF-5606A grade and is supplied in a one-gallon container under part number 1045377. X/C Aviation Hydraulic Fluids in this grade support use in non-pressurized systems from –54°C to 90°C (‑65°F to 194°F) and in pressurized systems from –54°C to 135°C (‑65°F to 275°F) at operating pressures up to 3,000 psi. Documented applications include aircraft and missile control systems, autopilots, shock absorbers, auto wreckers, boom trucks, electrical service equipment operated in all-weather conditions, industrial robotics, and hydraulic systems requiring a super-clean fluid in the X/C 5606H variant. The formulation is not intended for use in hydraulic systems containing natural rubber elastomers.
