This specification is being retained as a military detail specification because of the unique military requirements for use in systems operating in an environment from −65 °F to 250 °F. The reusable adapters covered by this specification are intended for use with hose conforming to MIL-DTL-8794 in fabricating flexible hose assemblies following such practices as in MIL-DTL-8795. The hose assemblies are intended for use in hydraulic, fuel, and oil lines. Flanged type fittings covered by MS27228, MS27230, and MS27232 are normally intended to be used only on fuel and oil lines. Size −3 adapters are not to be used with size −3 hose conforming to MIL-DTL-8794 in hydraulic applications (see table I).
