A/c charge fill hose help

[J king]

I am getting set up to be able to charge air in my cars. Bought a HF guage - hose set. Have a industrial vacuum pump that I need to put a fitting in it to be able to connect to the yellow hose from the pressure guage manifold.

I thought the hose was an fittings but I was wrong.can someone tell me what the male fitting would be called that the yellow charge hose takes.I keep reading it’s acme but have no idea what I need to buy. Thanks! Jim

I did order the can pierce adapter and it has 1/4 and an adapter to 1/2 I believe but I need the male that fits hose on one side and a 3/8 npt to fit into pump.

A HVAC local supply house should have something like this in the correct size or with adaptors

So it’s SAE- M?

1/4 male flare to what ever pipe threads are on your vacuum pump.
An HVAC supply house is your friend here or a great old fashioned hardware store,not a big box.
Acme threads are what is on the R134A manifold set.
Your yellow hose should be female Acme on one end and 1/4 female flare on the other.
You will need 3/8 male pipe thread to 1/4 male flare adapter .
I hope this helps.....

Also Yellow Jacket. Different refrigerants use different size fitting and pressures. R134A is quickly being replaced by R1234YF. Wow, is that stuff expensive !
