OMT 3-Way AC Manifold Gauge Set for R1234yf R134a R404a with 5ft Hoses

Reviewing Orion OMT 4 way ac gauges. I would give this kit slightly lower than 5 starts but 5 stars was closer than 4 stars. First what I like. The dials are marked very clearly closed and open. Each and all dials are marked. Other kits i looked at were not marked clearly. It gets a bit confusing if they are not marked. The gauges read the pressures even when the dials on the manifold are closed. Don't make the mistake of opening the high side valve/dial. Read the manual. I like the site glass in the center. Very useful to see whats happening and if gas or liquid is moving. This kit is easy to hook up and mine did not have any leakage even with just hand tight. The kit has some plastic on the hoses that act as a tightening wrench but I didn't even have to use those to make good connections. Well built kit. This kit works with self sealing cans and it is designed for self sealing cans. No issues getting the self sealing cans to work. The only downsides to this kit for me was the numbers that pertain to the R134a were a bit small. If you are visually challenged you might have to get some readers to read them. The numbers are color coded though so you won't get confused as to which numbers to read. The other thing is the plastic box it comes in, I wish the box was a bit bigger so i don't have to struggle to get the hoses back into it. Just a tad bigger on the box would be so appreciated. I would buy this kit again and i found it pleasing to use other than those two things which might not bother anyone else. I used the kit and added 7.2 ounces of R134A and now my ac is ice cold. Worked on 2006 Rav4. Three hose gauges would be totally fine. I used this kit only attaching three hoses because i did not do a vacuum of the system.

As someone who works on automotive HVAC systems, this was a fantastic upgrade. I already owned another manifold set from the same company for R134a systems, but this one is a game changer because it supports both R1234yf and R134a. It came with everything I needed to diagnose AC problems, pull a vacuum, and recharge the system. What I loved most is the 4-way manifold design. I was able to perform the entire service without constantly disconnecting hoses or equipment, which helped prevent ambient air and moisture from entering the system. The carrying case keeps everything organized, the quality is excellent, and it made servicing modern AC systems much easier. If you work on vehicle HVAC systems, especially newer vehicles using R1234yf refrigerant, I highly recommend this set. ⭐⭐⭐⭐⭐

Works great and 4 hoses is WAY better because lets you have fill can AND vacuum pump connected all at once. Worth the $$

Great kit comes with all the needed fittings. Guages are easy to read. Included hanger keeps guages from getting damaged and out of the way

Needed a reasonably priced set of gauges for a new 1234yf system. These gauges did the job but are not the quality of my older Matco and Snap On gauges. Some of the fittings were poorly tooled but worked.

Works great

Value for money

The gauge needle was jumped over the resting pin to the opsite side when arrived rendered the gauge unable to be used. I could open the gauge and move the needle back to zero position but I though it was completely damaged. The gauge functions as advertised and be able to use to vacuum and fill r1234yf to my car after replacing the compressor. Overall good product. Just beaware that needle may stack at high from shipping impacts.
