Yellow Jacket 49963 HVAC Manifold Gauge Set, Fahrenheit & PSI Scale, Compatible with R-22/404A/410A Refrigerants, Red/Blue Gauges Review

It's hard to be offended when you buy something in a yellow jacket. The valves are kinda loose. They move a little when they open. Don't bother. But they don't flow. The rest is wonderful.

These are great sensors, well made and do the job. You can't go wrong with the Yellow Jacket. I use them almost every day. You have made my work a lot easier. They're easy to fill, just pull out a quick vacuum. Try them, you will like them.

I am a trading professional and use these sensors every day and I tell you I couldn't be happier. 4-port design provides faster vacuum. They also have some weight. The collector itself guarantees no leakage throughout its service life. I'm glad I bought these

I liked the collector for two whole days, it started to squirt refrigerant. Thought it was coming from the yellow hose handle but upon closer inspection the sight glass was leaking. So now I have to either return this and wait a week for another, either buy a removal tool (another $30 with shipping) or make a tool.

I'm new to HVAC so I wasn't sure which sensors to choose. I did some research and came across this amazing set of sensors and didn't hesitate to buy them. I like restoring, pulling vacuum, charging with these gauges and observing the refrigerant through the sight glass. These valves are beautiful and durable, as long as you take care of them, they will take care of you.

Hello, I recently bought these sensors and they are good except the bottom side sensor broke after the second use. I went to vacuum, minus 30 and even with a screw I can't return it. With a set screw you can adjust it by just a bar or two. The rest of the sensors are great. I love her. I would like to give 5 stars. If there are no problems with the sensor, then I definitely give 5 stars.
