G1/2 pipe actual size is: pipe diameter 15mm, outside diameter 21.3mm.G is 55 degrees (non thread sealing pipe thread), belonging to whitworth thread. 1/2 marker refers to the inside diameter of the tube, the unit is inches. Insiders usually used to call thread size, an inch is equal to 8, 1/2 is 4 inches.Specific parameters:The size of code: 1/2The number of teeth per inch: 14 (i.e. pitch 1.814mm)Major diameter: 20.955mmMedian diameter: 19.793mmPath: 18.631mmNational standards are available on GB/T7307-2001.
