Reading the part number. M1183/5-33A is a military-specification slash-sheet number: it points to slash sheet 5 of MIL spec 1183, and the remaining characters (33A) encode the size, material, and finish options that sheet defines. Ordering by this number pins down the exact variant of the pipe elbow.
