NotesThis section contains information of a general or explanatory nature that may be helpful but is notmandatory.5.1 Material DesignationsUNS numbers are in accordance with SAE HS-1086. Aluminum temperdesignati
23、ons are in accordance with ASME H35.1. 5.2 CounterboresFor connector tube installations, the counterbore dimensions of Figure A1 and Table A1 arerecommended.5.3 ApplicationsConnector tubes and related items may be suitable for use in systems operating at pressuresexceeding 21 MPa (3045 psi) when sup
24、ported by design analysis. The O-ring glands for the connector tubesare designed in accordance with SAE AS 4716 for single back-up rings.5.4 Restrictor, Check and Relief Valve Inserts for Connector TubesThe tubes described in Figure 3 andTable 2 are designed to accept restrictor, check or relief val
25、ves. Not all of the available products of theestablished diameter will always fit within the length of the tube bores. In such cases, connecting passagesmust provide sufficient clearance for the protruding ends; i.e., at least equal to the maximum B1 and B2dimensions, as applicable. Consult product

27、fications MIL-C-24714 and MIL-C-24714/1. SAE J24714 part numbers are interchangeable withM24714/1 part numbers with the same dash numbers. (A “M” prefix was used for the military part numbersand a “J” prefix is used to designate the SAE part numbers. The ”/1” from the Military part number has beende
28、leted since J24714 has no separate specification sheet.) Dimensions herein are similar to the dimensions inMIL-C-24714/1. The outside diameter (dimension A in Table 1) and length (dimension C) of the parts areunchanged. The gland inside diameter and gland width (dimensions D and E in Table 1) of som
29、e parts havebeen changed to more closely conform to SAE AS 4716. Some changes have been made to the dimensionsfor the tubes for restictors, check valves and relief valves to accommodate additional configurations. The tubesherein meet the 0.127 mm (0.005 in) minimum squeeze goal of AS 4716 except for
30、 dash numbers 010, 114,117, 124, and 128. These dash numbers have a minimum O-ring squeeze of approximately 0.1 mm (0.004 in)in order to use standard gland inside diameters identified in SAE AS 4716. 5.6 Key Wordsconnector tube, ferrule, quill, transfer tube, counterbore.PREPARED BY THE SHIP SYSTEMS
