Default NPT and BSP taper threads

2009 m. spalis 21 d., trečiadienis 22:13:51 UTC+8, CS rašė:
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.

WHAT FITTING I WILL USE IN BSP IF THE OUTSIDE DIAMETER OF MY PIPE WITH THREAD IS 21MM?
