    Meh ...

    It worked, it's cheap but if you only need it for a once a year or every couple years job then it's good enough for that without spending 3-5x as much on a better gauge set.Mine came with the plastic lens on the high pressure gauge laying in the bottom of the box. The lenses are very cheap plastic, made like a mayonnaise jar lid and they screw on. So don't freak out if you think you got a broken gauge, just screw the lens back on.It doesn't have the high-pressure fitting that GM vehicles use on the high pressure side of the A/C system. So if you're going to use it on a General Motors vehicle AND you need a high side pressure reading then you'd better look into getting an adapter.It finger tightened up just fine on the fittings I used it for and it doesn't appear to leak or waste coolant, so that's a plus. I had no signs of a leak (frost is a very good indicator of a leak) and they connected up to what they fit on exactly as they should. If you... 2/5 S.L.

A used higher quality set from craigslist would be a better find. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , April 15, 2011

This review is from: 1/2HP 5 CFM Single Stage Rotary Vane Vacuum Pump w/ R134A Auto Freon AC Recharge Manifold Gauge Set Complete Combo Package (Misc.) The pump seems alright, probably about the same quality as most harbor freight pumps. The instruction manual has some really horrible English translations going on. Lots of typos and messed up punctuation. Kind of funny to read actually. On the box, one of the highlights on the pump is "perfect appearance", hah.The gauges it comes with are the typical crappy quality gauges. Probably will work a few times but highly doubt they'll last very long.

Read the reviews on this manifold set and it didn`t sound too bad so i bought it and also bought the Mastercool #85510 can tap valve to go with it. Everything was fine until i tried to connect the yellow hose to the can tap and found out it does not fit. Emailed Mastercool and they said that i also need fitting # 82635 around $6.00 that reduces the can tap from 1/2" down to a 1/4". Guess i will get that ordered now.

It works fine and seems to be of sufficient quality for home mechanic. It does everything you need it to do, however, you have to know ahead of time because this product doesn't come with instructions, ask a friend or some body before you use it. I am an electrician. But, I have a friend who is mechanic and air conditioning to help me. The manifold gauge worked great. I pulled a vacuum on the gauges and it held for an hours I left it sitting. I bought all my own A/C tools this time rather than having the local shop to work on my truck, Be sure to buy a can tap as well. I will say the instructions weren't great but if you know what you're doing you'll be fine. I'd recommend these to anyone. I looked at all the models on Amazon and I'm glad that I bought this manifold. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , January 24, 2012

    Good product; but risky over-simplified instructions

    The fundamental problem with any do-it-yourself product such as this is that air conditioning is a complex system that MIGHT be affected by the problem this kit MIGHT be able to fix. If your A/C system is low on refrigerant and it's simply because over the years some of the refrigerant has leaked out due to minuscule leaks (not uncommon if you don't run your A/C during the winter, and seals in the system dry out), you may be able to get your system back in action. If it doesn't work due to some dozen+ other possible problems with your system, you've wasted $40 or more to find this out.First, keep in mind that you are doing work that is potentially very dangerous. The refrigerant is under high pressure both in the can and especially in the system, and accidental exposure to the freezing liquid can severely burn skin or cause blindness. Heed the warnings to wear gloves and safety goggles! Also avoid breathing any gas that escapes, which should not happen unless you do... 2/5 Haef - See all my reviews This review is from: Interdynamics (ACP-100 PRO) Professional Formula R-134a Ultra Synthetic Air Conditioning Refrigerant with Reusable Dispenser and Gauge - 20 oz.

    Bad charging system

    0 1/5 santonm - See all my reviews This review is from: Interdynamics (ACP-100 PRO) Professional Formula R-134a Ultra Synthetic Air Conditioning Refrigerant with Reusable Dispenser and Gauge - 20 oz. (Automotive) It appears that in California you require an adapter to make the can work with the charging system and I have not been able to get the refrigerant to flow from the can to the car's AC. It appears that the adapter is not puncturing the seal enough and the can refrigerant never flows.After a bit more work on this, I tried another hose and dispensing system from another manufacturer that I had in the garage and discovered that the reason that the refrigerant was not going into the car's AC was due to the hose, coupler and dispensing trigger mechanism. When I switched to the other hose and trigger system, the fluid went in. So the problem was with the system used to dispense the fluid and not the can and fluid itself. This may have been a fluke, but I would still keep the one star rating for the poor quality of the hose and dispensing system that caused me to waste so much time on this project. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , May 22, 2013

I ran into problem when I found that these gauges did not come with low-loss fittings. So I had to buy low loss fittings for $26 from ebay. After I got everything I needed I tried them on. I have three central air conditioners. I first connected gauges to the one that has low gas and I got zero reading on both gauges. So I tried it on working unit and still got zero reading. I may be doing something wrong but looks like gauges are not working.

    0 4/5 Robert - See all my reviews This review is from: R134a R12 R22 AC A/C Manifold Gauge Set 6FT Colored Hose Air Conditioner Freon If you buy this for R134a recharing, make sure you buy the adapter for the 134a refrigerant tank (or can tap). The hoses have R12 fittings. The low and high side come with everything needed for R134a, but the utility line (yellow) does not. You will not be able to directly attach the yellow hose to a 134 tank. No store I've been to seems to stock the adapter. Make sure you buy the correct adapter though:134a to R12 Tank Adapter1/2" ACME to 1/4" flare This allows you to hook to a 134a tank and use R12 manifold gauge set.Don't accidently buy R12 to 134a.
