Frequently asked questions
The 3/4 inch designation (19.05 mm / 1.905 cm) refers to the nominal pipe size, not the thread diameter. The BSP standard accounts for pipe wall thickness, so the actual outside diameter of the G 3/4 thread is 26.44 mm.
The G (BSPP) thread has a parallel design with a constant diameter along its entire length. These connections require additional sealing – a flat gasket, O-ring, or Teflon tape.
