MIL-DTL-8789F
6.1 Intended use. These end fittings covered by this specification are intended to be used with
hydraulic pressure operating at 3000 psi.
6.1.1 Military unique rationale. The fittings covered by this specification are military unique fittings
that mate with hose, in accordance with MIL-DTL-8788, to form hose assemblies, in accordance with
MIL-DTL-8790. The military unique hose assemblies are intended to be used in high pressure hydraulic
systems requiring interoperability and compatibility with associated components and equipment. The
hose assemblies are required to withstand an operating pressure of 3,000 psi (206.8 bar). The
interoperability and compatibility has been assured through strict adherence to the military detail
specification requirements. Manufacturers of these items and users place great reliance on the detailed
technical requirements to ensure the products meet the interoperability and compatibility requirements
while encountering rapid ambient temperature fluctuations.
6.2 Acquisition requirements. Acquisition documents should specify the following:
a. Title, number, and date of this specification.
b. Title, number, and date of the applicable specification sheet and the complete PIN (see 1.2).
c. Level of preservation, packaging, and marking required (see 5.1).
6.3 Qualification. With respect to products requiring qualification, awards will be made only for
products which are, at the time of award of contract, qualified for inclusion in Qualified Products List QPL
No.8789 whether or not such products have actually been so listed by that date. The attention of the
contractors is called to these requirements, and manufacturers are urged to arrange to have the products
that they propose to offer to the Federal Government tested for qualification in order that they may be
