BSP is a British standard for pipe threads defined by ISO 7 & ISO 228. It is the most commonly used pipe thread system outside the USA. In North America, the more popular standard is NPT. Although it is a British standard and the nominal pipe sizes are in Inches, the dimensions are defined in millimeters. The Jargon, calculations, and charts ...
The most common G 1/4″ threads at WIKA are surely the G 1/4 in accordance with EN 837 or DIN 3852-E. But in addition there are many other pressure connections which are all specified as G 1/4″. For example G 1/4 Ermeto and G 1/4 DIN 3852-A, just to name two.
G (supposedly from German/English “Gas”) are the cylindrical pipe threads with 55° apex angle used on originally inch based pipes. BSPP thread is often referred to as “G” threads, the two types of thread are the same parallel straight, the threads are measured in threads per inch.
