Dimensions are in inches, unless otherwise specified, tolerance decimals + 0.010. 2. Thread “S“ shall have a multiple lead and a blunt
6、 start as specified in FED-STD-H28/2. 3. Break all sharp edges and remove all hanging burrs and slivers. 4. Serrated teeth of the locking flange must engage with the serrated teeth of the MIL-DTL-25427/6 coupling nut as a hose attaching coupling half assembly and ensuring positive locking. 5. For de
7、sign feature purposes, this specification sheet takes precedence over the procurement document. 6. Referenced documents shall be of the issue in effect on date of contract award. REQUIREMENTS: 1. Material -for material requirements, see procurement specification MIL-DTL-25427. 2. Finish -for finish
8、requirements, see procurement specification MIL-DTL-25427. 3. The surface of the aluminum alloy parts after anodizing, sealing area and surface treatment shall be free of pits, powder coatings, discontinuities such as scratches or breaks and shall be uniform in appearance. 4. Threads shall be produc
9、ed by die cutting or machining by single point method. 5. Marking shall consist of the part identification number, manufacturers name, trademark or CAGE code and shall be impression stamped or laser etched. The marking shall be protected from corrosion. 6. Interchangeability. The coupling plug shall
10、 be interchangeable among manufacturers having the same tube size and pressure class. Type I coupling plug configuration and dimensions are known to be similar to Parker coupling plug P44000, Eaton coupling plug 155-S9, and Type II plug is similar to Hydraulic International plug DC-L. Suppliers seek
11、ing to be on QPL-25427 are responsible for interchangeability and shall perform the manual operation test to ensure coupling plugs manufactured are interchangeable with other suppliers couplings or coupling plugs and vice versa. Users are cautioned to check the dimensions for their specific applicat
12、ion. 7. Operation. Connection and disconnection of coupling plugs with MIL-DTL-25427/3 hose attaching coupling half assembly shall be easily accomplished using a one-handed turning motion. The coupling plug shall function as required in MIL-DTL-25427 when connected to a MIL-DTL-25427/3 hose attachin

The test shall be performed in accordance with applicable test requirements of MIL-DTL-25427. Suppliers seeking qualification of new coup
14、ling plugs are responsible for interchangeability of their coupling plugs with the existing qualified couplings. The qualifying activity shall perform the manual operation test of the coupling plugs provided by manufacturers whenever necessary to ensure interchangeability and leakage within the allo
15、wable limit. 9. Part or identification number (PIN). The PIN shall consist of the letter M, the specification sheet number, a dash number from table I, a material code, pressure class, and style.
