Fire Hose Brass Adapters, Valves, Y's - 375
The most common fire hose threads in British Columbia are: 1" to 2" NPSH and 2-1/2" BAT (larger sizes must be confirmed but are typically NH - or also known as NST). NH/NST is more popular in the USA. 'Male NPT' will seat on 'female NPSH' threads, but 'female NPT' and 'male NPSH' will not mate. BAT Thread (made in 2-1/2" size only) will not interchange with NPT, NPSH, or NH threads.
