Orion Motor Tech AC Manifold Gauge Set for R410a R22 R134a Refrigerant, 4 Valve Automotive AC Gauge Set with Antishock Gauges Hoses Couplers Adapters, Puncturing Can Tap Freon Recharge Kit, Black Case

Great quality. Does the job. Different in the respect of using older machine where one has to disconnect yellow line on machine between vacuuming and filling. Great for older machines, Not automatic machines. Saves time, has, the environment 😂.Only down side is the plugs missing to hold taps. So used old set male plugs and fixed to machine.

First off, complete novice on AC and this set.My three cars all had poor performance ac during one of the heatwaves.I found this and investigated further. I was told that a gas refill alone would cost me £50.I wanted to be sure this was right and the product was brilliant.1. Everything you need in one hard plastic case.2. Good instructions3. Robust parts, metal valves and decent reinforced pipe.4. Everything is colour coded for easy set up.5. Accurate large description gauges.6. A multi accessory box included in the kit.It allows a one connection point to read the pressure of both the low and high pipes of your ac system.You can then attach and fill or actually release some to avoid overfill damage.It has helped me fix all of the cars and only two needed a gas top up which I did myself.The price I paid was i believe worth it all items paid for in first use by doing it myself.I recommend this product for helping you fix your car AC system.

Great equipment

I'm not sure how good this is for AC split units as the vacuum seems to not go as low as I think the pump can go but its fine to check for leaks.And as a bonus I can also use it for my car!But did have to buy an adapter to make it work with split unit AC systems.

Gauges seem good but hoses do not fit back in the case and it all needs to be disassembled to put back.

UPDATE: The kit came with adapters which allowed me to connect my vacuum pump!-----Gauges seem to work fine, but the vacuum hose doesn't thread onto the standard vacuum pump connections. I have a brand new one and a 20 year old one. Same problem. I'm stuck with a mini split install that I can't complete.

This is a very good manifold set with everything you need to to diagnose your a/c system ,paid for it self the first time i used it on my vehicle . Only one thing i dont like about them is that the hose come loose very easily .

Muy buen producto de muy buena calidad los materiales

This Orion Motor Tech 4-way gauge set has been a workhorse for my HVAC work. The gauges are accurate and easy to read, with clear color coding that makes quick diagnostics simple. The manifold feels solid and well-machined—no cheap plastic parts here.The hoses are good quality with secure fittings that don't leak. I've used this set on R410a, R22, and R134a systems without any issues. The four-way design gives you plenty of flexibility for charging, recovery, and vacuum operations.What impressed me most is the accuracy compared to my more expensive professional gauges—they're right on the money. The case keeps everything organized and protected, which is great for mobile work or just keeping the shop tidy.For DIYers or pros on a budget, this set delivers professional-level performance without the premium price tag. I've put it through dozens of jobs now and it's held up perfectly. No regrets on this purchase whatsoever.If you need a reliable gauge set that actually works, this is it. Highly recommend!

Excelente juego de manómetros para servicio de aire acondicionado, estoy encantado con el detalle de las llaves de plástico insertadas en cada manguera para darle el ajuste final al apretar, también el que sea de 4 vías hace que el vacío y la carga de gas sea mucho más práctica, creo que compraré otro juego!
