In the past I have rigged various fittings to pressure test components like this oil cooler. 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 a condenser. Before I go science project on it, does anyone have a good off the shelf solution theyve used? These are common 3/4" and 5/8" fittings.

Every flush & test fitting I own was made from a scrap hose assembly of some sort.

Any "You Pull It" type salvage yard has your parts waiting. A couple of wrenches and a pocketknife will get you mating fittings.

If you use a short length of hose with a crimped on fitting, you can go with a hose barb & clamp for your air fitting. Plug the other hose & fitting.
