General notes:
- Dimensions are in millimeters unless otherwise indicated.
- Socket Bore (B) – Maximum and Minimum dimensions.
- Bore Diameter (D) – Maximum and Minimum dimensions.
- Socket wall thickness – (C) – Average of Socket wall thickness.
- Dimensional tolerances laying lengths – (E & F) NPS 1/2 and NPS 3/4 = +/- 1.5 mm NPS 1 to NPS 2 = +/- 2 mm NPS 2½ to NPS 4 = +/- 2.5 mm
