anyone know thread size/pitch of axle/transfercase vent/breather tubes?

yeah so on my FJ i made up a snazzy little breather relocation spot by using pnuematic fittings and tubing going into a manifold block with a filter. Really clean looking so I am trying to figure out the pitch and thread size of the tubes....My 8.8 has a 7/16-20. The Dana 35 and transfer case are the same but couldnt find anything at home depot that fits, its a 3/8 size but didnt seem to fit the fine thread of 24.

I believe the t-case fitting is 1/8" or possibly 1/4" NPT (pipe thread). I can't say for sure which though since it was maybe 7-8 years ago I had the thing out. If I think of it, I'll check the one on the t-case I have sitting in the garage tomorrow.

i believe you are correct i didnt even think about npt....it is no type of standard pitch so it must be that. It is for sure 3/8 though
