1/ Dimensions are in inches.
2/ Metric equivalents are given for information only.
3/ Assemblies having aluminum flange fittings shall be pressure tested at the rated proof
pressure or 1,500 psi (10.3 MPa), whichever is less, see MS20756.
3.6 Identification of product. The hose shall be identified in accordance with MIL-STD-130. In addition,
the hose shall have a band attached near the ends of each hose length and for hose lengths more than 10 feet
long, an additional band attached near the center. For hose lengths that are 30 feet or more, an additional
band every 10 feet. Each band shall contain the following information:
a.
PIN (see 1.2), length designator may be omitted.
b.
Cure date in quarter and year such as 4Q08 for fourth quarter 2008.
c.
The rated working pressure in psi.
d.
CAGE code.
e.
Manufacturer's name or trademark.
3.7 Cleanliness.
3.7.1 Clean. All hose lengths shall be free of oil, grease, dirt, moisture, cleaning solvents and foreign
materials both internally and externally.
3.7.2 Closures. The cut hose ends shall be sealed with caps or plugs conforming to NAS847 to prevent
the entrance of foreign contaminants. The caps or plugs shall be securely attached and shall withstand normal
strains, jarring and vibrations encountered during shipping, storage and handling. Hose lengths with uncovered
ends shall be rejected and considered as failure.
