This hose/fire protection cover combination lasts many times longer than unsleeved hose and provides high performance in demanding power plant air frame applications.
How its Made Inner Tube: Seamless, specially formulated synthetic AQP compound.
Reinforcement: Stainless steel wire braid consisting of partial inner braid and full coverage outer braid with an integral silicone cover.
Specifications, Fluid Compatibility: versatile inner tube is compatible with nearly all petroleum-based oils, aviation gas, JP fuels, and synthetic-based fluids including MIL-L-23699 lubricating fluids. Unaffected alcohols, coolants and solvents commonly used in aerospace systems.
Operating Temperatures: -65`F to +300`F
Testing: AE401 hose assemblies were subjected to extensive qualification tests. A copy of the test report is available upon request.
NOTE: Consult Aeroquip for approval before using AE401 hose in hydraulic impulse pressure applications.
Aeroquip 666/667 Medium Pressure Teflon Hose
Aeroquip 666 and 667 medium pressure Teflon hose is widely used in Aircraft applications handling fuel, oils and other fluids. The economy of the reusable fitting concept for military applications has been well established. Special fittings which represent up to 80% of the cost of a hose assembly are completely reusable. Engineering mock ups can be made quickly on the spot from a small stock of bulk hose fittings. Hose lines obsoleted by engineering changes can be readily salvaged and reworked unto usable assemblies. This means inventory requirements can be greatly reduced. There are no ordering delays or waiting for factory assembled hose lines.
