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
