NPT and BSP taper threads
I am looking at getting some water filters, 20 inch housings, with 3/4
inch NPT female connections in plastic tops. Can I get away with screwing in 3/4 BSP TAPER male brass compression fittings, using a good wind of PTFE tape?? Both NPT and BSPT are 14 TPI and the nominal NPT is 1.050 inch OD and BSPT is fractionally smaller at 1.041 inch OD, so should fit in. I know that there is a 5 degree difference between thread angle.

You could certainly try to get away with it, or - perhaps more seaman-
like - install an NPT - BSPT adapter. A quick search shows wide availability, including: http://www.mcmaster.com/#brass-threa...ttings/=45nv6s MW Los Angeles |
