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 2.1/2 to NPS 4 = +/- 2.5 mm
