NPT or BSP: how do I tell which thread a fitting is?
| NPT | BSP | |
|---|---|---|
| Thread angle | 60° | 55° |
| Where used | US, Canada | UK, EU, Asia |
| 1/2 in outside diameter | ≈20.9 mm | ≈20.9 mm (looks similar) |
The trap: 1/2 in NPT and 1/2 in BSP look almost identical and thread a few turns before leaking. Count threads per inch or use a thread gauge.
