I have an aluminum AN832-3D (bulkhead union, two male 3/8-24 UNF w/ 37° flares). I need to connect it to a brass male 1/8 NPT fitting and can't seem to find a female/female fitting-coupling that will do the trick.
I agree with the caveat about galvanic corrosion. Are there aluminum connections on the other side of the bulkhead union? Any chance of changing the bulkhead fitting to a more compatible metal?
if only it was an AN-3 and at $37 is more than I would like to spend.
swall - I agree corrosion is a concern. However the BH fitting attaches to an aluminum channel. The BH fitting is a lot cheaper and easier to replace than the Al channel. The treads will have ARP thread sealer added that should help with corrosion.
The brass fitting is existing hardware for 1/8” copper tube brake lines. Replacing the lines is out of the question. The system I’m designing is a kit. I would like to keep the fittings so the end user does not need special tools to change it and can go back to original equipment.
