The elbow fitting drop height shall be as shown on figure 3 and table IV. When applicable, the

22、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 with MIL-DT

23、L-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 inches to 36
