Orion Motor Tech AC Gauges: Complete 3-Way Automotive AC Manifold Gauge Set with Hoses, Couplers & Adapter for R134a R12 R22 R502 - Freon Recharge Kit for HVAC Review

The hoses I received had the connectors crimped on one end only. Which I didn't notice until I connected the coupler to the port on the low side and the hose ripped off the fitting, causing refrigerant to squirt. Luckily I stood to the side so I didn't get hit and I was able to remove the coupler from the A/C line before too much refrigerant was lost. a small note against self-folding tubing.

For the price, you can't beat Guage. No, it's not Snap-on, nor is it hundreds of dollars at stake. The Dual is easy to set up, I just wish I could calibrate the device more accurately. A better guide would help and make it easier not to make silly mistakes when ordering for the first time. Remember that the laws have changed, you need an adapter for new refrigerant cylinders. But it's also great because if you keep the old one, you can now restore it and save it, or reuse it or dispose of it…

I bought this primarily to fix an air conditioning problem on one of my cars that I'm still working on. In the meantime I'm just using it to make sure everything looks good on my other two cars. So I plugged and unplugged the quick disconnects maybe 4 times in total. The blue (low) side of the quick disconnect has already failed. I've replaced the small plastic grommet on the end of the blue hose that connects to the blue quick connector to no avail. I also replaced the yellow hose with a blue…

There are some positives, although this is a one star rating: No leaks when vacuuming after wrapping threads with Teflon tape. The sensors seem to be sufficient. Cons: 1. Hook won't hold - may need to add thread lock 2. Okay, it's big. The average hose thread is 1/4 inch and will not fit regular faucets. So you CANNOT charge if you don't find the right faucet. I bought the exact same model sold in national auto parts chains. Today I visited 4 of them Autozone, Knech, O'Reilly and Napa. NOBODY…

Unfortunately, my review does not provide any information as to the accuracy or reliability of this product. .I received my gauges on time and was ready for a long weekend. I had an extra weekend to see what was going on with my car which wasn't that cold anymore. and high ports. It's not rocket science, the quick couplers fit easily enough but don't snap when released. There doesn't seem to be enough play for the latch mechanisms to pull out far enough and then latch properly over the…

As a mechanical engineer in the HVAC industry I figured why not test them out and see how effective they are. I can tell you I rode these things hard all day, not just the R22 and 134a. I checked with a tee and my Testo manifold, the readings are accurate but ***in Celsius*** when I ordered them I was high and wasn't paying attention. Regardless, the sensors themselves have been deployed in a real HVAC area for a month. I'll start with the hoses. They were cheap as dirt to begin with and worked

I am not an air conditioning expert and have no experience diagnosing or repairing air conditioning. The gauges were easy to assemble and use. The sensors are in Celsius as others have commented. Gauges come with everything needed for R-134a systems except for a canister faucet and an adapter is included to convert from a gauge kit to a canister faucet which I purchased separately (I have my own R-134a Faucet bought locally, but it's similar to taps offered on Revain by WINOMO or Interdynamics…
