NPT Specifications
NPT thread diameters are omitted because the source repeats the G-table diameters. Confirm the NPT dimensions for the required configuration.

Guia de Seleção
Match the thread form and pitch, required airflow, finish and available space to the table. The two M12×1.5 entries differ by finish. Retain the printed M16×1.5L designation when requesting the 19 mm H configuration; the M16×1.5 entry lists H 21 mm.
