🔧 LICHAMP AC R1234YF R134A Gauge Set: Efficient Automotive 4 Valve Manifold Gauge for R1234YF and R134A Refrigerants Review

Totally useless. came with the wrong hoses (R410a) which will NOT fit R1234 adapters, specifically the charge hose (yellow) will not connect to a 10lb tank or 8oz valve.

If you have any questions about your car, simply ask them in the questions section. The answer came very quickly. The product arrived on time and was very easy to use on my car. When using R1234fy make sure you cover the adapter completely or you will damage the glass. Overall great experience and easy to use!

Pressure gauge set suitable for checking and topping up coolant. However, useful guidance is missing. You need to learn how to use it properly. Also, for some reason, the high pressure side doesn't connect to my AC pickup. I wrote to the seller and he replied but found no solution.

Maybe a bit too expensive for this quality. The pressure gauge set does not fit properly in the supplied case. The valve stems appear loose, but the seal is fine. Can't fault the lack of instructions, instruction manuals don't come with wrenches, you need to know what you're doing. The supplied glass tap is useless, not suitable for R134A or R1234yf cans, the old type of punch is used with R12 cans. One end of the black tubing is not 1/4" but 5/16".

I returned it. I wanted to use it to refill my 2018 civilian car with paint. I blasted the line to the point where the blue coupler met the blue hose and when I started to fill up my car I couldn't see the coolant flowing through the sight glass, the blue gauge showed pressure. The air conditioning in the car was switched on for 15 minutes, nothing. I think the pusher in the clutch is not long enough to open the car's valve. It was like pumping up a tire.

Cheap ratchet imported Chinese hoses. Thumb nuts are great when they stay closed, which is rare. I have another 134a set from a well known brand and they are second to none. I tried swapping out the hoses but the adapters on the manifold are an odd size. The 134 and 1234 adapters seem decent. The valves seem fine. Pressure readings are comparable to yellow vests. The fill hose will not fit standard canisters without the use of another fitting.

This is based on 40 years experience as a car mechanic. Need a new 4 way junction kit saw this for 134a and 1234yf so I thought it was a good idea. Cons, poorly cut threads due to fittings, they constantly come loose even after tightening with pliers. The hoses are too short and stiff. Gauges are hard to read I never thought about it but the PSI range is in the middle ring and it's hard to read along with the middle making the readings inaccurate. Bad quality all round. Advantages, only one…

Instead of hiring sensors like I've always done, I decided to buy my own set. My wife advised me to order a good set from well-known brands, but I didn't listen because a good set is expensive. I ordered them and they look good but when first used on the r134a the high side connector failed and the oil and coolant mixed throughout the engine bay. A tiny green O-ring flew out of the connector. I managed to find the black o-ring and got back to work. Other issues are the can tap is useless and I…
