RF 96 Radiator Bleed Tubes

[CJD]

My RF 96 has the two plastic radiator bleed tubes and I want to replace them with -3 braided line. Does anyone know what the thread size for the swirl pot and the radiators are? I'm not sure if they are NPT or SAE. I want to make sure I get the right fittings. Thanks for any help.

I think they are BSP (at least mine are)

Sizrm121, thanks I hadn'd considered that.

NPT will have a visible taper.

BSP thread dimensions can be found in the Pegasus catalog as well as NPT

I just had Pegasus look over my radiator bleed tubes and they can identify the fittings that attach to the swirl pot and they are indeed BSP. However they can't identify the fittings that attach to the radiator and none of the fittings they have match. Anyone out there know what these fitting are? I'm completely baffled with something that should be so simple. Thanks for any and all recommendations.

Picture?

I sent the two bleed tubes to Pegasus and should have them back shortly. I'll post some photos once I have them.

Alcon, FYI. I just determined my radiators have metric threads for the bleed tubes and the swirl pot uses BSP. Wanted to pass on to the group. Also a shout out to Pat Prince for his recommendations..
