A.1.1 Scope. This comm
27、ercial item description (CID) covers the general requirements for conical seals, crush, 37 degree flared tube fitting, aluminum alloy. Conical seals, crush, 37 degree flared tube fitting, installation procedure covered by this CID are intended for commercial/industrial applications. This appendix is
28、 not a mandatory part of the commercial item description (CID). A.1.2 Intended use. Crush seals are intended for use with 37 flared tube fitting ends in accordance with SAE-AS4395 or SAE-AS4396. A.1.3 Characteristics. Crush seals are subject to compression; therefore, a double torqueing procedure is
29、 used. A.1.4 Torque technique. In order to assure a seal a drop of oil or compatible lubricant may be added, see table IV, to the threads of the connector and a drop to the conical seal prior to assembly. A.1.5 Torqueing procedure. 1. Thread tube nut onto male connector several turns with fingers un
30、til connection is snug. NOTE: If tube nut cannot be tightened snugly with fingers, disassemble and correct problem to prevent assembly damage to crush seal. 2. Torque to suggested torque values in tables AI, AII, AIII or manufacturers recommended torque. Allow compression yielding of the crush seal
31、for 15 seconds then re-torque to the values in tables AI, AII, AIII, or manufacturers recommended torque. 3. If for any reason after hand tightening, after the initial torque, or yielding torque the assembly has to be unassembled a new crush seal shall be used upon reassembly. 4. Do not tighten tube
32、 nuts more than specified in table I to avoid damaging the crush seals. 5. Do not loosen tube nut after initial torque application without replacing crush seal.
