Hinweis: this tool calculates per Chinese national standards (GB) and ISO. For US inputs (psi, inch), convert to MPa / mm first using the converter above. Stangengewindes may be entered directly in US form (e.g. 1/2-20 UNF, 1-14 UNS); the drawing will auto-convert the major diameter.

US thread designation: major dia (inch fraction) − TPI + series (UNC/UNF/UN/UNS) + class (2A external / 2B internal), e.g. 1/2-20 UNF-2A. Pitch mm = 25.4 ÷ TPI.
The G value is the pipe nominal size (not major diameter), e.g. G 1/2 has 20.955 mm major dia; sealing is by face O-ring or gasket (BSPP), with PTFE tape for taper internal threads. NPT is a 1:16 taper thread sealing by thread deformation; use sealant with NPSC/straight ports. G and NPT have different flank angles (55° vs 60°) and are not interchangeable. G/NPT are used for ports and piping, not piston-rod ends.
