A/C expension valve thread size
#1
Hi guys
Rebuilding my a/c system and building custom length a/c hoses. I need to purchase 2 Male O Ring Type, Nut, Crimp On Hose Fittings 

I am just wandering if anyone can tell me what are the thread sizes on the expension valve so that I can order correct fittings?
Thanks
Alex

Can't say but you should be able to measure the dia. and then count the number of threads per inch. I would expect they are straight thread pipe threads for the compression fittings.


When a man is in the woods and talks and no women are there is he still wrong??

Thanks for your help. So I found that back from 50's through 80's they used AN fittings for ac . So in this particular case i will need # 6 and #10 Male oring fitting.

I guess thread is universal for AN fittings as long as you know the size you need.
