Fittings: All fittings shall be qualified in accordance with MIL-DTL-27272. Hose: The hose shall be qualified in a

20、ccordance with MIL-DTL-27267. Assembly classification: Class 1 and class 2 hose assemblies, as specified in MIL-DTL-25579, have been incorporated into the Part or Identifying Number (PIN) as a part of styles (see tables I and II and figure 1). Angular alignment: Hose assemblies with elbow fittings o

21、n 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 2). The elbow fitting drop height shall be as shown on figure 3 and table IV. When appl

22、icable, 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 included in the PIN. Fire protective sleeve shall be subjected to testing in accordance

23、 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 be as follows: a. 1/8 inch for lengths under 18 inches. b. 1/4 inch for lengths from 18

24、inches to 36 inches. c. 1/2 inch for lengths from 36 inches to 50 inches. d. 1% for lengths over 50 inches.
