LICHAMP AC R1234YF R134A Gauge Set, Automotive 4 Valve Manifold Gauge Compatible with R1234YF and R134A Refrigerants, Works on Car Freon Charging and Evacuation

I love that it has a separate hose to pull vacuum on the system. My old gauges only had a single hose so I had to swap from the vacuum pump to the r134a bottle which means you'll let a little air in. With these gauges you just close the vacuum hose and open the fill hose which you've already vacuumed so there should be essentially no air in the system at all. The r134a fittings are also quick connect so it's much easier to use.

I love how these gauges have separate knobs and hoses for vacuum and refrigerant charge. build quality and finish are great.

It's a decent set. A couple issues: 1) the low pressure r1234yf coupler doesn't fit. The quick connect fitting is about 0.5mm too short for the vehicle low pressure shrader valve stem. I had to file it down to make it work. 2) forget about the can tap in the kit. You need to buy one that actually works. I understand the vendor probably have a bunch of such kit already made and it's not practical to replace the can tap. Why don't you just lower the price by $10. 3) the kit comes with a couple pages that shows a connection illustration and a few words on how to vacuum, charge, etc. No explanation on how the 4 ports works. This is important because for people who have been using the 3 port system, this is different.

Buena calidades

I used this to evacuate and recharge the R1234yf ac system on my Honda, and it worked perfectly. The hoses were long enough to reach the service ports while hanging from the hood latch, the 1234 port connectors fit well and sealed without any issue, and it even included the right adapter fitting to connect to the vacuum pump I rented from the auto parts store. The only thing that wasn't included was the R1234 self sealing can tap, but that was only $8 on Amazon as well and worked just fine with this manifold set. If you know what you're doing, this set will work just fine for you. The included instruction sheet is more of just a "contents list", but if you need more thorough instructions, you should probably watch some videos before tackling AC charging, and maybe consider enlisting the help of someone more experienced in charging ac systems as well.

Pros: This manifold did the job for me. Valves all work and seal well. I like that it has separate ports for freon and vacuum. I like that it has a case.Cons: I hate that the hoses have angles on one end of the fittings. Idk how the can tap is even supposed to work. It looks like the worst design I’ve ever seen if it’s supposed to work on the little cans (I bought can taps separately and used them instead). The hoses don’t seem to stay tight, so keep an eye on that. Lastly, idk if it is my vehicle or not but I barely got the low side coupler to attach to the low side port of my vehicle (r1234yf). I tested the r134a couplers on another vehicle and they worked completely fine.So there it is, I used to have a nice manifold so these leave a lot to be desired, but they’re cheap and they work.

Used it multiple times and it works as expected. I did have to buy a separate adapter for the self sealing cans but thats it. It gets the job doneWould recommend this product to others

This is based on 40 years experience as a auto tech.Needed a new 4 way manifold set, saw this one for 134a and 1234yf so I thought sounds like a good idea.Cons, poorly cut threads on the fittings cause them to continually come loose even after a snug with pliers.Hoses are to short and stiff. The gauges are hard to read, never gave that a thought but the PSI range is in the middle ring and hard to read along with being in the middle makes the readings inaccurate. All around poor quality.Pros, just one, it is a 4 way manifold set as described.If was hurting for money, which I am not this would have got sent back for a refund.
