About G Thread (BSP) To NPT (US Thread) Pipe Fitting
This brass adapter is required to convert G (BSP / BSPP) to NPT. The G (BSP / BSPP) standard is used in Europe and around the world. Although the threads look incredibly similar, they are not compatible. The NPT (US Standard) thread is tapered with a 60 deg thread pitch and designed to seal when the threads compress together, with pipe tape to fill in any minor leak paths. G (BSP / BSPP) thread is parallel with a 55 deg thread pitch and designed to seal with a Bonded washer seal (included with our fittings) or an O-ring face that may be machined into your fixture. If your fixture has a machined O-ring face you can dispose of the included seal and just use the adapter. If your fixture does not have a machined groove with an O-ring you will need to use the included seal. The seal fits very tightly over the male end of the G (BSP / BSPP) connection and a water tight seal is formed when they are screwed together. This is like a US garden hose which has the seal the inside of the connection, G fittings use the seal on the outside and have some type a metal ring or machine face to prevent the seal from blowing out.
