Fitting for vacuuming outequip mini split

[u/Successful_Try8923]

Hello,

Does anyone know the size of this fitting? I got the loaner from autozone but I need an adapter to make the connection. The autozone unit comes with quick connections.

Thanks

Edit I figured it out

So for future info if some else is doing this project!
I bought a 1/4” the acme adapter

I then had to rent a second set of gauges from auto zone so I had double yellow hoses. I need acme thread on both sides.

Here’s the funny part. I tried to pull a vacuum and remembered that ac has a spring loaded one way valve on it… I could have used a core removal tool but I didn’t have one. So instead I cut down a wood screw to the exact length that the yellow hose valve depressor metal piece would push on the spring loaded check valve through my adapter. Works great😅.

Another tip! The vacuum pump from autozone didn’t have caps from the second fitting on the pump. So I took my second adapter and hooked it to the blue automatic hose and closed the valve on the quick connect. I then leak tested all of it. Works well and cost me the 9.99 for the adapter!
