Worked very well! Let me pull a vacuum down to 500 microns! Usually these less expensive adapter fittings leak to much to let you pull a good vacuum.

5.0 out of 5 stars Fits my R134a low pressure port and angled so I utilize my hose length better on my ac charge hose
Reviewed in the United States on September 12, 2020
Verified Purchase
I needed an angled low pressure connector for my 2016 chevy traverse because of the rediculous location of the low pressure ac port. This worked perfectly. I had previously bought a 59” charge kit hose and the connector that came with it would not connect even though it was the right size. I swapped it for this one and was able to connect correctly.

I bought these connectors so that I could connect a quality set of refrigerant gauges to my truck. I was able to evacuate the system safely and then pull a vacuum on the system with my vacuum pump. I was then able to charge the system accurately. Good quality tool that did exactly what I needed it to do.

These are great. I bought them to use with my yellow jacket gauges and charge my truck. For such a low price I didn't expect such good quality, but I can add these to my colleection if fittings that I can use over and over unlike the cheap charging kits you buy at auto zone.

Fit the truck a/c fitting perfect and worked great. Just be sure you have your gauge hose attached first because there is no schrader valve inside this fitting. I am just used to the valve being there.
