FIGURE 1. Hose construction - Continued.

3.4.1 Hose. The hose shall consist of seamless compounded inner tube of oil resistant synthetic

rubber or copolymer and of uniform gage, reinforced with 18-8 corrosion-resistant steel wire in a manner

to meet the requirements of this specification and retain end fittings, in accordance with MIL-DTL-83798,

without leakage or other malfunction when tested as specified herein.

3.4.2 Length of bulk hose.

3.4.2.1 R designator of bulk hose lengths. Bulk hose shall be furnished in lengths greater than 20

feet (6.10 m). However, up to 10% of the order may be furnished in random lengths between 10 and 20

feet (3.05 to 6.10 m). No more than 10% of the order shall be furnished in random lengths between 3 and

10 feet (0.91 to 3.05 m).

3.4.2.2 S designator for specific bulk hose lengths. When the order is for a specific length in feet, a

tolerance of �1% of the required length shall be used.

3.5 Performance.

3.5.1 Examination of product. The hose shall conform to the requirements of 3.7, 3.8, 3.9, and on

figure 1 when visually examined as specified in 4.7.1.

3.5.1.1 Cleanliness check. The hose shall be free of all foreign material, both internally and
