19、tables I and II, and figure 1). Angular alignment: Hose assemblies with elbow fittings on each end shall have the angular orientation between the elbows measured counter-clockwise from the centerline of the nearest fitting, positioned at six-oclock, to the centerline of the other fitting (see figure

20、 2). The elbow fitting drop height shall be as shown on figure 3 and table IV. When applicable, the angular alignment shall be expressed in three digits and specified in the PIN. Protective sleeve: If required, the hose assembly shall include a protective sleeve (see table III) and its code shall be

21、 included in the PIN. Fire protective sleeve shall be subjected to testing in accordance with MIL-DTL-25579. Assembly length: Hose assembly shall be furnished in lengths as specified in the contract or purchase order (see MIL-DTL-25579); however, tolerances on the length of each hose assembly shall

22、be as follows: a. 1/8 inch for lengths under 18 inches. b. 1/4 inch for lengths from 18 inches to 36 inches. c. 1/2 inch for lengths from 36 inches to 50 inches. d. 1% for lengths over 50 inches.
