Cal Hawk Tools CZFCGA Manifold Gauge Set

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.

loved the carrying case it comes with, works great, good for the price...didn't like the fact that the hose gave problems while trying to close the case, my open/close stickers fell out quite easily...nothing a little glue wont fix...have to buy the r134 bottle adapter separate since it does not come with this set

Pro, cheap, worked for a few years.Cons, Hooked up to a car and the High pressure line exploded at 210psi, spraying my face and engine bay.I was in a pinch and needed to still use them and so i just hooked up the low side and after a few mins, i heard a "hiss" and saw it was also leaking at only 45psi.So apparently after 5-6 years these hoses "time out"

This was perfect for my A/C repair. ZERO leaks, everything sealed up nice and tight by hand. The main reason I picked this kit over the rest, besides the cost, was because it had the good quick disconnect with the turning knob so that you don't accidentally damage your Schroeder valves on your high and low pressure lines. For all those complaining about the yellow hose not fitting the can tap...go buy a more expensive can tap that does have a 1/4" outlet or just buy the 1/2" to 1/4" adapter to use with you cheap universal can tap. Look, it's right here: http://www.amazon.com/gp/product/B0002JMF9I

It is very good quality for low price, but the yellow hose didn’t fit the R134 can tap valve. I had to order fitting # 82635 around $6.00 to make it fit (it was waste of time). Besides that, I am happy my car is nice and cool now!!!

Not happy with the the adapters that came with it. While the hoses and gauges performed OK, could never get the quick adapters to seal properly. Had to find some other adapters or hook hoses directly to an AC system to stop the leaks.

Functional, well-built and accurate. This was not what I expected when I ordered a unit that was made in China. The long hoses are nice, since I work on large trucks where the service ports are often hard to reach and/or far away. No needle "flutter," which is nice. This is a good piece for the novice mechanic, the professional who occasionally does A/C work, or for DIY types who want something that works well. I don't like blow-molded cases, but this unit comes in one. I threw the case away, because I had a place to hang my gauges.

The gauge was delivered in record time and I thank Amazon for that. I did my ac repair and was ready to evacuate and recharge. The gauge set is not professional quality, but is good for the money and good enough for anyone that does occasional recharges and diagnosing system pressures. I hooked up my vacuum pump and evacuated the system with no problems and the gauges read well. Something you must be aware of is the 1/2" acme threads on the lines fit the the vehicles OK but the center line (yellow) will not fit the small 12oz. cans you get at Autozone, Advance Auto, etc. The hose will fit the bigger 30lb. cans, (maybe they do this for a reason), so I had to go to Advance Auto and buy a hose/gauge adapter for the smaller cans for $25.00 to charge the system. Everybody that buys a manifold gauge set doesn't have 30lb. refrigerant tanks, a lot just want to charge their system with the smaller cans and check pressures. I would give this gauge set another star if the kit had an adapter to fit the smaller cans.
