Setup for pressure testing auto ac condenser (3/4 + 5/8 ports)

[R-mm]

In the past I have rigged various fittings to pressure test components like this oil cooler (first pic). I usually submerge it in water to look for bubbles and check that pressure holds.

I'm sure there is a common way of doing this for an ac condenser. Before I go science project on it, does anyone have a good off the shelf solution theyve used? Mine has common 3/4" and 5/8" fittings.

I would just hose clamp some heater hose on it. Put a tire valve in one hose and put 10-15 psi on it and dunk it into water.

Yeah what homebuilt burner suggested would be the easiest.

You can also get something like this is you are willing to spend some $$$
