Questions & Answers
This set is a 4 out of 5 star rating. 5.0 out of 5 stars, with some reviewers providing high-quality details. Doing your homework on the internet, comparing sources of information to see what makes sense, and writing your own instructions notes are all good ways to learn how to use them. Anyone who discourages you is most likely an air conditioning technician who despises the fact that people can learn to do what he charges $250 per hour for so easily. As if a tax attorney is warning you about the dangers of filing your own taxes- It's not for everyone, but it's also not difficult.
Yes, I do have a r134a reading.
It has served me well. There were no issues at all.
As far as I'm aware, there aren't any. It's possible that you'll have to get in touch with the vendor. One you-tube video gives a quick overview of the pump and gauge. tube. Search: "Are Jay the redneck vacuuming an air conditioning system with a vacuum pump." If the video I sent comes through, another option is to watch it.

Because the seller demanded a five-star review before I had a chance to use the product, they are docked one star from the top. I despise it when a seller requests a five-star review without allowing the buyer to use the product first. br>br>It's a good thing I haven't left a review yet. After unpacking everything and attempting to connect it all, I quickly realized that I would be unable to use the gauges to actually add refrigerant to my truck. The adapters will not fit on the yellow hose because the connection is too tight. The adapters as well as the refrigerant valve will not screw on. In other words, I'll have to use my other set of gauges to add the refrigerant. Anything other than vacuuming on the a is a waste of money. systembr>br>CURRENT UPDATE: After removing the vacuum from my truck's ac system and charging it, I discovered that the high pressure gauge no longer works. will be returning the entire system.
Purchased to be used in a vehicle. The fittings on both quick connectors were only finger tight, and the high-pressure quick connector had a bad leak even after tightening them. I even tried taping the fittings with plumber's tape, but it didn't work. I requested a replacement from the manufacturer but did not receive one. Also, because the gauge set is 1/2 in. , the can tap that came with the kit didn't fit. The yellow service line is 1/4 in. long and ACME female. This had to be purchased separately because he was a male. When pulling a vacuum, the gauges didn't seem to be accurate, but because of the leaks in the fittings, I can't say for sure. Every piece of equipment in the set had terrible instructions. The A/C sniffer, in my opinion, would never detect a minor leak. My high-pressure schrader valve and evaporator both had leaks that it missed. Bottom line: this kit contains all low-cost components that will not do the job and will only result in more work, wasted refrigerant, and poor customer service; do yourself a favor and purchase individual components of decent quality.
There is no way I could give anything less than five stars. I installed this set on a residential heat pump and it worked perfectly; there were no leaks anywhere, including at the hose connections. The dials are easy to read and understand. I'm not sure how long the plastic knobs will last, but they appear to be in good condition. I can fit all of my adapters in the case because it's large enough. For the time being, it's working for me. I'll post an update if I discover any issues with this gauge set.
The pump performed admirably, achieving a pull of around 30 pounds. (Vacuum measuring accuracy is hampered by dials with a narrow range of vacuum. ) After 40 minutes, the pump began to heat up. I ran refrigerant into the low side port after evacuating, but the manifold was leaky and blew refrigerant out around the high side gauge. br>I hope it lasts for a few more runs. I completed the task, but I have no idea how much refrigerant was lost. I switched hoses and read it off the low side gauge, which was much higher than the high side gauge. It's a mess. br>I have my doubts about the readings. As a result, I've decided to purchase a Y-chromosome. This one is being discarded in favor of a manifold. If I could do it all over again, I'd go with the Y. First, I'd buy a manifold for around $120, and then I'd go to H. and invest in a good pump that comes with a solid warranty. If you plan on using the equipment more than once, it's a good idea to invest in something well-made.
The equipment was in working order, but the leak detector was not. It's low-cost, low-quality, and as soon as you turn it on, it emits a refrigerant reading that's off the charts, regardless of where you are. I tried it on the porch, inside, in the car, and in the bathroom with the door shut. When I held vacuum for 45 minutes, the system did not show a leak, but after the service, my system was leaking through the service port, which it did not detect correctly. All of my refrigerant leaked out of the service port, resulting in a 5 hour and $60 loss, which I was not pleased with. While it would have been a 5 star review if they didn't include this cheap tool, which is so important, they threw it in as an incentive, so now I have to double my time and money for new refrigerant and a working leak detector, another week without air conditioning (currently 104 degrees), and the environmental cost of leaking all that refrigerant into the atmosphere. The kit worked perfectly, but assume your leak detector is broken and replace it with one that does.
Don't get me wrong: it does the job at a very reasonable price. If you've worked as an HVAC technician with the Yellow Jacket brand, you'll be disappointed. But it works; the price reflects the quality of the machining and accuracy; I've repaired three vehicles' air conditioners with this setup, and it hasn't let me down yet. Just make sure to re-oil the vacuum pump after it has been revived. The level indicator is a little sluggish and unreliable. Nearly half of the oil that came with it was added. A hum should be heard from the pump. Overfilling will not harm the pump, according to the instructions. With these pumps, it's better to be over-full than under-full. If the pump is making a lot of noise, it's time to change the oil, no matter what the sight glass says. I hope this has been of assistance.
It was extremely helpful in diagnosing and repairing the air conditioning system. You must remove the shrader valve from the brass fitting adapter if you plan to use the 12 oz cans of refrigerant.
Analog meters appear to work. This was purchased with one goal in mind: to use a mini split line set to evac/pull vacuum The centerpin/plunger on the 5/16 adapter isn't long enough to engage the Schrader valve pin, as others have pointed out. Other hose connectors have a tendency to back off the threads, requiring you to check connections for tightness on a regular basis. The extra seals and adjustment tool they include appear to be a shoddy workaround for this obvious flaw. I'm glad it worked for some people, but it's a complete gamble.
