1、-524a4 ABSTRACT January 4, 1994 SUPERSEDING MIL-C-62005A 30 September 1982 MS35746F 2 September 1981 MS35748E 28 January 1974 COMMERCIAL ITEM DESCRIPTION COUPLER, AUTOMOTIVE AIR BRAKE LINE : QUICK-DISCONNECT The General Services Administration has authorized the use of this commercial item descripti

2、on (CID) as a replacement for MIL-C-62005Af MS35746F, and MS35748E, which are canceled. This CID covers requirements or a quick-disconneck air brake line coupler half with a replaceable preformed packing designed for use on pneumatic hose where rapid coupling and uncoupling is required, and on vehic

3、les where a low-pressure, quick- disconnect connection for air brake lines is needed. SALIENT CHARACTERISTICS a. Materials. Unless otherwise specified herein, the materials used shall be in accordance with the manufacturers materials spcifications/drawings. The use of recovered material made in comp

4、liance with regulatory requirements is acceptable providing all the requirements of this CID are met (see note f.). 1. Metals. Metals used in construction of couplers shall be corrosion resistant or shall be protected to resist corrosion during the length of service. 2. Preformed packing. Preformed

5、packing shall be made of synthetic rubber which shall meet the applicable performance specified herein. I Beneficial comments, recommendations, additions, deletions clarifications, etc. and any other data which may improve this document should be sent by letter to: I U.S. Army Tank-Automotive Comman

Design and construction. Unless otherwise specified herein and in figure 1, couplers shall be designed and

7、 constructed to the form and dimensions in accordance with SAE J318. Couplers shall not have a service lug or other design features that would restrict interchangeability between service and emergency 1 ines. 1 a 2. Interchangeability. Coupler halves shall be physically and functionally interchangea

8、ble; any two, when randomly selected and joined together, shall form an airtight connection (see note e.). c. Performance. Unless otherwise specified herein, the coupler shall meet the performance requirements of SAE 5318. Low temperature testing shall be done at -65 degrees Fahrenheit (OF). 1. Thre

9、ad tensile strength. Coupler halves shall withstand a tensile force of 1000 pounds (lbs) applied coincident with thread axis while exposed for 24 hours at an ambient temperature of -50F +5OF followed by similar exposure at 250 - +SF without causing air pressure leak at threads. 2. Compression. Coupl

10、er halves shall withstand a load of 500 lbs applied perpendicularly to the sealing face on each locking jaw in the direction of force normally resulting from compression of packing. When loaded in this manner, there shall be no permanent set to the packing and coupling shall continue to operate afte

11、r 24 hours exposure at -SO0 +5OF followed by 24 hours exposure at 200 +SF ambient temperatures. - - d. Identification and marking. Identification and marking shall be permanent and legible and shall include as a minimum, the manufacturers CAGE - code and part number, and the part identification numb

Contract certification. The contractor shall certify and maintain substantiating evidence that the product

13、offered meets the salient characteristics of this commercial item description and that the product conforas to the producers own drawings, specifications, workmanship standards, and quality assurance practices. Items with known defects shall not be submitted for Government acceptance. The Government

14、 reserves the right to require proof of such conformance prior to the first delivery and thereafter as may be otherwise provided for under the provisions of the contract. PRESERVATION, PACKAGING, PACKING, LABELING, AND MARKING Preservation, packaging, packing, labeling, and marking shall be as speci
