🌡️ AJ Tools CHIMG777 Manifold Gauge Set: Optimize Your HVAC System's Performance Review

Seems fine. I was expecting it to fit the low pressure side fittings (larger threads) AND the high pressure side fittings (smaller threads) on my R-12 air conditioner in my collection truck. Not so. (I already have a box full of adapters, but wasn't ready to buy more small parts.) Both fittings were only the size of an R-12 low-side fitting, so I returned it (very easy!).

Can't complain for the price. 1. I have only used it once so far. I ran the vacuum for 2 hours and it worked great, I also left it plugged in overnight and it never leaked. Some have commented that the hoses are quite short and stiff, also the fittings when the hoses are not in use are designed to screw the hoses straight onto the gauge which is fine but you will need the quick disconnect from the Unscrew hoses do that.

Pays for itself with first use. The hose and the connections make a solid impression. I have no leaks. I took someone's suggestion of putting teflon tape on the threads. Also be careful, the o-rings can come loose. Mine stayed in place but if it comes loose I can see it's going to be hard to find on the floor. ARS tried to charge me $700 to add Freon to my block. It's in degrees Celsius, but it's easy to convert. I don't know how long the gauge will last, but for the average layperson, it works

Received everything exactly as described and shown in the picture. If you are a regular shade tree mechanic then this is the perfect addition to your toolbox. I was able to quickly connect to my old machine. Using an old R12 system plus hassle free connection to a home AC system. You will need adapters if you are using newer R134 systems, but these adapters can be purchased at a very reasonable price. Why pay hundreds of dollars for something you'll probably only use a few times a year when…

Did not claim quick couplers. I had to return it and buy another one she has or spend another $14 and wait 3 more days for her. I didn't know car systems actually had quick disconnects, but they do have threaded connections. I understand it. The manometer indicated correctly, the screw connections were tightened. I had to tighten the screws holding the handles. Without the hype about the fast connection I would have given four stars.

Worked well for HVAC repairs on my 4Runner. I had to use some adapters as they are only for R12 (adapters: http://www.amazon.com/gp/product/B000JFHNEC/ref=cm_cr_ryp_prd_ttl_sol_16). One reviewer noted that the lenses were removed upon receipt. Mine were too, but they're supposed to be removable, so it doesn't matter. The only issue I've had with them, and the reason I'm knocking them off the star, is that the connectors have these little rubber O-rings. I had these parts twice. The hoses have…

I received 1 Pit Bull CHIMG777 quickly. Although KO Tool Supply advertises high quality products, the manifold I received had a (plastic) lens cap loose (removed) in the package and the manifold design (valve stem on the bottom) was loosened, leading to some Loss led (leak) of freon. I tightened it and replaced the lens and all is good. This distributor does not include "Quick Connect" connectors and they are a bit tricky to use. These ports also can't just stay tight on Schrader valves…
