Master #A402

Have been using this set professionally with repeated success over and over again. These are by no means high end but for someone starting out in the trade that doesn’t want to spend hundreds of dollars on a set of gauges, I couldn’t recommend these more. The ONLY thing I don’t like is there’s no way to loop the hoses to make a sling. Kind of a pain going up a ladder.

I purchased this kit to replace a 40 year old set of gauges I had. This is a nice quality looking kit. I can't attest to the accuracy since I have no way of calibrating the gauges. The gauge housing seems very sturdy and nicely machined. I like the five foot hoses as they make it easy to hang from the latch with the hood up and still reach the connections. I also like the plastic wing nuts that slip over the hose fittings and makes it easier to snug them down. The adapter set is complete. The only negative is the gauges are a bit small to read. These are standard sized gauges so I can't complain too much about that. My older eyes would appreciate slightly large dials for readability. It gets the job done at a reasonable price. I paid much more for a cheaper set of gauges 40 years ago. I do recommend these gauges.

Decent value for basic HVAC work. It gets the job done, but the gauges aren’t the most precise. Still a useful set for light use.

I needed a set of gauges for 410a. Skeptical of buying a less expensive set, I found these for $80. Can in a hard case box, all the accessories plus more than expected. Has a vacuum line and attachment on the manifold as well. No leaks. Hand tighten for high and low is all I needed. Purging air worked flawlessly. Cracked open the valve and back of with no leakage there. Great set for Auto or hvac.

This set is high quality and very complete with accessory fittings. I used the "Ref" valve with included hose to add refrigerant from a 12-ounce can of R-134A. The can tap was included, too.

Do NOT use Teflon tape!! These work great but lack instructions and one is that if you have a flared male end going into a female with s gasket you will mess up your seal with Teflon tape. Look it up if you don’t believe me. Teflon tape wasn’t made to handle the high psi and super cold liquid Freon, it’ll blow and leak every time. I think most of these reviews complaining of leaking used the tape or wrong side of the hose. Pay attention you can get badly hurt! Otherwise this is a great set and and saved me gobs (I have r22) and found out I was very low. The cost of these gauges are less than a service call

My air was acting up on my car that was over 10 years old and I was getting tired of taking it to the dealer. The last time I took i in the mechanic said it costs $50.00 just to hook up the gauges + parts and labor. I used to work on cars in the 70s, 80s and 90s so I was familiar on how a car AC system works and how to use the gauges. I was able to fix my car and now the air blows at 42 degrees even being 13 years old. The kit comes with everything you need to test and recharge (top off) your system. I have also topped off my family and friends cars and I normally get a 6 pack as a thank you so for me it was a great investment. Scale = 1 Star - I Don’t recommend - Returned; 2 Stars - Don’t Recommend - Kept Product; 3 Stars - Recommend - Meets Expectations; 4 Stars - Recommend - Exceeds Expectations; 5 Stars - Perfect 10 (rare)

Very well organized storage unit with easy to read dials. Vacuum cut off valve works makes work much easier.

Muy buen equipo cumple muy bien su función llego en tiempo y forma

الصيني صيني فاشل في كل الاحوال

The 2 r410a safety valves broken in single use, not even finish the job

Good set of gauges for refrigeration works, but the seals inside the hose adapters have dislodged within a month of use.

Exelente equipo
