These gauges work well, and fit! I replaced two defective gauges on an old manifold and it restored it to like new. I would buy again.

Haven't used these yet, just got them delivered to me today. Seems of good quality. Plastic covers are attached with a plastic pop-plug to pull out when needing to realign the needle back to zero. I highly suggest getting a set of rubber boots for extra protection because the covers doesn't seem to twist off and on like other quages. Going to update this review or write a new review after a couple of weeks of use, to give a more honest opinion on the durability and functionallity.

These are quality gauges at a good price. I was able to refurbish my old R-22 manifold set with these gauges. No more using my good R-410 set to check and older R-22 system. There are other gauges on Amazon that are cheaper, but if you zoom in on them the PT for R-22 doesn't look standard. These gauges provide the old school PT reading. R-22 at 40 degrees should be around 69 on the pressure reading.

Bought these for HVAC to use them as stubby fittings to reduce refrigerant loss as opposed to hooking up manifold set. Very easy to read and visually appealing gauges

I do a/c work daily.I wear out/ break guages all the time. They are very expensive to replace from my suppliers.Thought i would give these a try, If they did not last, or broke easily i did not have much money into them.To my surprise they are as good as expensive ones, hold adjustment well, i have dropped them many times and they are still together and did not need adjusting.I am very pleased, will buy them again and highly recommend them!
