    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.

This review is from: Pit Bull CHIMG777 Pit Bull CHIMG777 R12 A/C Air Conditioning Ac Refrigerant Manifold-Gauge Set (Tools & Home Improvement) The product is as it is displayed. The hoses are very short and it does not come with the 3/8 fitting/hose for the alternate high pressure fitting used on some vehicles.If you really want to be able to get the job done, your going to have to buy and additional set of fittings and adapters.The set is sufficient quality for a weekend warrior / hobby mechanic, but I would not recommend them for professional use, there are much better sets out there. 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

    Great Gauges!

    0 5/5 andy dirt - See all my reviews Verified Purchase(What's this?) This review is from: Manifold Gauge and Hose Set, 4 Valve These are top-notch quality gauges from good ol' Yellow Jacket! The four hose design is very convenient. You can evacute your enitre manifold set and hoses and then charge your system without having to worry about purging. They come with standard length hoses WITHOUT low-loss fittings! I strongly recommend picking part # 93842 which is a 3 pack of 1/4" 45 degree angle ball valves. Automatic low loss valves are bulky and seem to fail at the least oppurtune moment! Make your life easier and go for the ball valves! They fit perfectly and still allow for neat hose arrangement when not in use. Don't forget to take the core depressors out of the hose ends before installing the ball valves. They won't do anything but restrict flow! I would also pick up part # 49190 which is the protective gauge boot set for this manifold. You can't get a nicer set of gauges for this price. They need a few add-ons to be the best but, they're worth it! 0 Help other customers find the most helpful reviews  Was this review helpful to you? , August 1, 2013

The 134a refrigerant cannot enter the system with the car engine off. When you press the button to fill the gauge jumps up to the red 'danger' level.

    4.75 Stars for an EZ AC Fix

    I'm not an expert, so I really liked that the refilling process was simple.1. Wait until the weather outside is between 75F to 85F (because that's what temperature gauge was calibrated to(some other refrigerants have a variable weather adjustment, but not this company)).2. Turn your car on, set the AC to full blast and wait a few minutes.2. Screw the small end of the hose to the refrigerant can head.3. Attach the big end of the hose to the low side port by holding back the quick release of the hose and then letting go of it when the hose is on the port.4. Let the gauge measure the pressure. If your gauge is not working correctly, it's probably because your compressor is not spinning (it stops spinning when your car is really low on refrigerant). You need to add a bit of refrigerant at this point just to get a pressure reading.5. Take the blue cap off the can and spray for a couple minutes.

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. If you need something that lasts this probably isn't it. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , March 28, 2014

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. I will update after I try other set of gauges but until then I can only give these gauges one star, I would have given them less than one since they have not worked for me. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , July 31, 2011

This review is from: 500 PSI A/C Manifold Guage Set (Automotive) 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.

    0 5/5 Samaky Hay - See all my reviews Verified Purchase(What's this?) This review is from: 500 PSI A/C Manifold Guage Set (Automotive) 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
