R1234YF Adapter, R1234YF to R134A Quick Coupler, 1234yf to 134a Quick Coupler, High Low Side Connector Conversion Kit AC Charging for R1234yf Refrigerant Air Conditioning System Hose Fitting

Excellent purchase

As a retired a/c tech I have a need, from time to time, to service various air conditioning units. My new car and truck have R1234yf refrigerant and I needed these adapters in order to perform my services on them.They are very well made and operate smoothly. Fit is spot on and they are colour coded to high and low pressure with red and blue respectively. Designed to allow a set of R134a gauges to be used instead of another dedicated gauge set. Saves money and that is always a good thing.Comes with the high and low connector and R123a adapters that fit the gauge set. Also includes the caps for the adapters. The one thing that would make this the perfect adapter would be the adapter for the distribution tank to fit the R124a gauge hose.I am pleased that I do not need to purchase a total replacement gauge set to service these systems.

Works in a pinch to allow using 134 hoses for a 1234yf car. No leaks and no issues.

Used these on a newer car to refill the AC. The low side snapped on clean and stayed sealed with no leaks during use. Everything felt sturdy enough for a basic recharge. The high side was harder to press in once the system had pressure, so it took a bit of effort to get it seated. Not a major issue, just something to keep in mind. Gets the job done.

This adapter set works exactly as described. The functionality is great, both high and low side connectors fit securely, and the leak-free design makes AC charging and diagnostic work much easier. The brass material feels sturdy, and the knurled grips make attaching and removing them smooth and hassle-free.For the price, the quality and performance are impressive. It’s a reliable, well-made tool set that delivers great value for the money.

These adapters are made with solid metal that feels heavy and strong. The brass is thick and smooth, and the red and blue parts have a nice grip texture that makes it easy to hold. The threads are clean and fit perfectly without feeling loose. Overall, The material is durable and sturdy.

Solid construction and connects quickly. Saved me time and hassle during my AC service. Works exactly as described!

Used it multiple times with no problems. Sturdy build and secure connection. Exactly what I needed for my AC work!
