Fitting: MIL-DTL-8789 (Also MS28760, MS28761, MS28780, MS28781)
Hose: MIL-DTL-8788
Hose Assembly: MIL-DTL-8790

Example of a Military Part Number: MS28759-40204
(Hose assembly, flared, straight fittings, 20-1/2" in length, for 1/4" tubing, steel with aluminum sockets.)

Hydrasearch MS28759, flared, high pressure hose assemblies can be used as flexible connections on high pressure power plant and airframe applications (See SAE-AIR797). They are especially suited for high pressure hydraulic fluids, engine oils, fuels, and coolant fluids. Hydrasearch high pressure hose is used for applications with operating pressures to 3000 PSI, and having a temperature range of -65ºF to +275ºF (See MIL-DTL-8788 for specific temperature ranges).
