Got a part in your hand and need to know what screws onto it? Our fitting finder starts from your thread and lists every compatible part, with the inch / millimetre conversion.

Not sure which fitting you need? Tell us what you have, we show you what screws onto it — live prices and stock.

Pipe thread chart: inch / mm conversion (BSP, 15/21, 20/27, S60x6)

A “1/2 inch” thread measures 20.96 mm, not 12.7: in plumbing, the inch size is not converted, it is read from a chart. Here you will find the inch / mm correspondence of every common thread (BSP or “gas thread”, French names 15/21 · 20/27 · 26/34, NPT, S60x6 IBC tanks, Guillemin, Camlock, PVC), a tool that identifies your thread and the fitting that goes with it, and the pitfalls to avoid.

Which thread do you have? Which fitting do you need?

No need to know the name of your thread. Tell us what you need to connect to, or type what you know (“20/27”, “3/4 inch”, “S60x6”, “26.4 mm”): we identify the thread and show you the fittings that go with it. Dimensions according to ISO 228, ISO 7 and ASME B1.20.1.
