AC A/C Oil and Dye Injector Refrigerant Tools with Snap Quick Coupler R-134a R410a R22 R12 System 1/4" SAE Scale Refillable Line 2 OZ Hand Turn Screw

I was very pleased with this tool as it is well made, easy to use, and well equipped A heavy load. You need to unscrew the top of the body (the top has a hose attached) and unscrew the body all the way out until the 2 oz is exposed. You can use the capacity or less than 2 ounces if you don't need the full amount. Pour the compressor oil into the tool up to the full line (about 3/8" down from the top of the tool so that it has enough Screw on the top again With the tool standing upright, and the coupler detached from the end of the hose, I threaded the body in to force oil up the hose until it was just visible at the end this forced all the air and matter out of the hose and Once the hose and coupler were screwed onto the end of the hose, the coupler was connect to the low side R134a fitting on the car, it was started, and the system was working. I turned on the a/c and slowly screwed in the tool, until all of the oil was injected into the system (over the course of 2 or 3 minutes). It was very easy to use and I easily injected a couple ounces of PAG oil into my car after changing the compressor. Oil is stored in a capacity of 2 ounces at a time in the tool.

Basically, the included low-resolution music is too low, so it doesn't play the sound well There is a copper ring inside of the connector on the side port adapter, which would not fall out, and I was afraid to pry it out at risk of damaging it. Here is a photo of the actual address (see picture). It meant the adapter could not be used, in which case you couldn't inject the oil unless you had another adapter. I also found that the knurling on the oil injection gun was extremely sharp, hurting my hands after just a bit of oil injection. * For those curious, if you inject oil into the low-pressure line you will be able to see the oil glow If you run the compressor, you will see the side port. In the bench, an initial amount of oil is poured into the compressor to lubricate it upon startup (there is a tag stating how much oil is poured into the compressor). It is normal for a system to store approximately six items You should use 8 ounces of oil and, if you are replacing the compressor/accumulator, you should also use the A/C solvent to clean all the other components. With this, you will be able to compare how much oil you're putting in the system with the previous one.

I always made sure my system had plenty of A complete overhaul of the air conditioning system uses 10 ounces of oil. There were times when the system would be a bit noisy, and I felt that adding all the oil at once may have put stress on the compressor as liquid (oil) was compressed. During this latest repair, I added oil to the system but I didn't add the 2oz of oil that was in the oil injector. My next step would be to engage the low pressure switch by bridging and disconnecting the low pressure switch so that oil could circulate within the system after engaging the compressor. I was unable to rotate this compressor before initial engagement due to its lack of an external clutch. When the compressor had been engaged 15 times and the system had 3/4 of a can of Freon installed, I engaged the system continuously and charged the In my case, I was able to inject my 2 oz even with a full Freon charge, while the compressor was turned off. I was worried for a moment that maybe I would have needed to engage the compressor to reduce the low side pressure but that was not necessary. I would recommend this tool. I received it on time and the vendor built it well for a great price.

It was a bit hesitant for me to purchase this tool since it doesn't yet have reviews from other users. However, I gambled anyway, and I was very pleased that there was no leak, this tool seems extremely sturdy, and I was able to inject additional PAG oil at the low side without any issues. This has been used twice without a problem so far. It was delivered at a reasonable time and at a good price.

It may be necessary to use this to manage some older AC systems that you work on when you begin to understand AC systems. I have found it to be very useful since it has labels that tell you how much you need to add, and it does not leak or cause any problems so far. So far I've charged 2 systems with it and am on my way!.

The tool does not use the "STARTIONING LINE" scale at the bottom.

There doesn't seem to be any way for the car port to latch onto it and allow me to leak refrigerant. My experience with other couplers and the equivalent of the blue sleeve is that they easily spring up and down, but this one doesn't. This is the second one I bought, I returned the first one, and now I'm wondering if I just don't understand how the quick coupler locks onto the carport. Has anyone else had this problem?.

The AC machine in my house is ancient, which allowed me to need an oil injector. have decided on this one, so far I am happy with it! Has no operating instructions or parts list, so if it breaks, I guess it gets thrown away and a new one is purchased! It's great to see it last!.
