Great for older John beam machines.
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.

Easy to use, saved me money and im much cooler now.
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 instructions 3. 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.

Been using this for fitting AC split units.
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.

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

Quality gauge set that won't break the bank
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!

Good value for DYI’ERS
I have 3 other manifolds and wanted a 4 port this filled the bill. For home HVAC and auto A/C servicing this will get the job done . This is not a Yellowjacket or Robinair and at a fraction of the price it’s of reasonable build quality. With the proper knowledge and experience one should expect good service life . The people that have posted negative reviews about leaking etc. haven’t got a clue that if you over tighten fittings they will leak because the seals will be distorted or damaged! For a technician whom will be using it on a daily basis this is not for you!

Super prácticos
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!

Useful kit but the resealable can valve tap is a bit finicky
Really useful kit for doing A/C system work like recovering, recharging and leak testing. It's well made the only complaint I had was the valve tap for resealable refrigerant cans was a bit finicky to get flowing properly but other than that I'm really happy with the kit
