- Height A for NPS 1/2–12: hardhatengineer STD chart and Vishal Steel weldolet calculator agree; NPS 2 (1-1/2 in) also in a separate inch table.
- B and C only where shown in search results (hardhatengineer, cross-checked by Vishal Steel).
- NPS 24 height A conflicts: hardhatengineer 144.5 mm vs Piping-World size-on-size table 136.53 mm — left null. NPS 24 B/C single-source.
- Wermac reducing-weldolet tables give different A/B/C (reducing vs size-on-size types) — do not mix.
- Extra-strong (XS) heights only partially found (NPS 2 1.5 in, 2-1/2 1.625 in, 8 3.875 in, 10 3.6875 in) from a single chart — not tabulated.
