Orion Motor Tech 4 Way AC Gauge Set for R410a R22 R134a Refrigerant, 4 Valve Automotive AC Manifold with 5ft Hoses, R410a Adapters, Can Tap

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.

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!
