Source levels
Main value = the modeled value (nominal, else the middle of min-max).
Grey under a value = its min-max, where the source gives both.
< / = = the source gives only that limit, modeled at it. ref = reference.
L2 = the standard itself (or its complete free preview, or the maker's drawing).
L1 = two or more independent sources agree: the release gate.
LO = one source only: printed amber and marked *.
c = a source value was corrected; the datasheet says how.
House convention = a detail no source dimensions, drawn to a stated house rule. This size's values: L115.
Notes
mm unless marked (in): the thread rows are ASME B1.20.1's inches, x 25.4 exact. Lengths: the close nipple and the stock lengths two A733 makers list (DO1). Pipe: ASME B36.10 Schedule 40, nominal OD and wall; no weld seam.
Each end: full thread to L2, vanish threads to L4 on D (ADR 0127 row 5).
45° chamfer to the thread root at each end: house convention (DO2).
NPS 1/4 lengths: close (7/8 in) to 12 in, 17 parts; shown at 1-1/2 in.
L4 = 0.5946
L2 = 0.4018
L1 = 0.2278
