Yellow Jacket 19173 5/16 Female Quick Couplers x 1/4 Male Flare

Angled fitting works well in tight spots.

I used it to pull a vacuum on my new mini split.

Exactly what I needed. I used it to connect my HF vacuum pump and gauges to my mini split heat pump to evac during install.

Perfect adapter to use your standard refrigeration gauge set and hoses to hook into the 5/16 access ports on a mini-split condensing unit. One bit of advice, remove the Schrader (bicycle) valve from the adapter as the condensing unit has its own and by removing them from the adapter you can pull a better vacuum as there is less impediment to flow. Just used it on my install and pulled a sub 500 micron vacuum.... (you do use a micron gauge, right?) Now, if someone can direct me to an adapter for the odd ball drain line fitting on the indoor unit! Probably some metric size. Measures about 7/8 and nothing on the plumbing shelf seems to work......
