Notes from the standard

  • Dimensions in inches. Unless otherwise specified, tolerances ±.016.
  • Both fitting ends per SAE-AS5132; thread C per SAE-AS8879, with a 1.5-thread relief. Angle between the legs 45° ±2.5°.
  • Machined surfaces 125 µin Ra and forged surfaces 250 µin Ra unless otherwise specified (ASME B46.1).
  • Part number: AN, the sheet number, the size dash number and the material code letter. Unassigned part numbers shall not be used.
  • The aluminum code D has been replaced by W. Titanium alloy (code T) is not for use in oxygen systems.
  • For new design use material code R or W. Each part number is listed with its replacement SAE-AS5187 number; evaluate the replacement for the particular application.
  • Marking: the AN part number and the manufacturer's CAGE code, name or trademark.
  • Approved data governs. Use the part the drawing, SRM or IPC calls for.
