A vital (literally) measurement is the angle and major diameter of the cone at the end of the bleed nipple. The angle must be exactly the same as the Factory part.
Usually the angle is 90 degrees but who knows if there are variations.
I suggest the cone angle of the replacement bleed nipples need to be very precisely measured and compared to the original - assuming the original is correct !
Of nerdy interest is that the seat of the caliper will have a slightly different angle to the bleed nipple. In theory this produces a very small concentric sealing surface with very high pressure from tightening the threads. Seems counter-intuitive but it has worked this way for many decades.
