MIL-DTL-8790F
4.9.8 Over-tightening torque test. Hose assemblies when subjected to over-tightening torque in
accordance with SAE-ARP908 shall meet the requirements of 3.7.7. The hose assemblies shall be
attached to mating adapter ends (SAE-AS4395 or SAE-AS33514).
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the
contract or order (see 6.2). When actual packaging of material is to be performed by DoD or in-house
contractor personnel, these personnel need to contact the responsible packaging activity to ascertain
packaging requirements. Packaging requirements are maintained by the Inventory Control Point's
packaging activity within the Military Service or Defense Agency, or within the Military Department's
System Command. Packaging data retrieval is available from the managing Military Department's or
Defense Agency's automated packaging files, CD-ROM products, or by contacting the responsible
packaging activity.
6. NOTES
(This section contains information of a general or explanatory nature which may be helpful, but is not
mandatory).
6.1 Intended use. The rubber hose assemblies covered by this specification are intended to be used
in aircraft hydraulic systems. The rubber hose assemblies are required to withstand an operating
pressure of 3,000 psi and be able to withstand temperatures -65°F to +275°F (-53.9°C to +135°C).
6.1.1 Military unique rational. The rubber hose assemblies described by this specification require
qualification (material, part, and process), and on site audits, which include traceability of parts. The
rubber hose assemblies must be capable of interoperability and compatibility which can only be assured
through strict adherence to the detail specification sheet requirements. Commercial parts are not
designed to be interchangeable with aircraft hydraulic systems.
6.2 Acquisition requirements. Acquisition documents should specify the following:
a. Title, number, and date of this specification.
b. PIN of hose assemblies to be furnished in accordance with the applicable hose assembly
detail specification sheet (see 1.2).
c. Bent tube orientation angles (when applicable).
d. Packaging requirements (see 5.1).
e. Shelf life requirements (see 6.2.1).
6.2.1 Shelf life. This specification covers items where shelf life is a consideration. Specific shelf-life
requirements should be specified in the contract or purchase order. The shelf-life codes are contained in
the Federal Logistics Information System Total item Record. Additive information for shelf-life
management may be obtained from DoD 4120.27-M, Shelf-life Management Manual, or the designated
shelf-life Points of Contact (POC). The POC should be contacted in the following order: (1) the Inventory
Control Points (ICPs), and (2) the DoD Service and Agency administrators for the DoD Shelf-Life
Program. Appropriate POCs for the DoD Shelf-Life Program can be contacted through the DoD Shelf
Life Management website: https://shelflife.hq.dla.mil/.
