In addition to connecting directly to the vacuumed pump, it also has connections to the high and low pressure sides of the auto air conditioning system. However, you will/may need an adaptor to get the gas out of the can. (12 oz versions are usually available in retailers).
You should be able to fit at least one of the adapters it comes with
Rather than buying a cheap oil and leak detector, you should buy an oil and leak detector that is quality. I do not have any problems with the unit.
hose quick couplings to clip on the sides to prevent dirt from getting inside and R134 can be found both on the inside and outside.

As soon as I knew when I would need it, I bought It leaked vacuum pump oil all over the place when the first time I tried it. To add insult to injury, it also is past the return deadline. Please do not use this brand!
EDIT My discovery was that it leaks because of the way it's constructed. As a result, the screws holding the tank on are too long, and they bind before the springs are compressed It is enough to use a ring gasket. What needs to be fixed The screw can be removed (metric allen size 4mm), and a washer can be inserted under it. Make sure the screws are tight. For all four allen screws holding the tank to the wall, repeat the above steps. You should be able to seal it up There are washers in size #6 that you need. The pack of 30 I have at home is - You can purchase it for $1 in our depot.
In a nutshell, In short, it turns out that the refrigerator I have hanging on my sandwich top has no After getting it back to work by myself, I decided to keep it that way. There is only one thing I need to do add The unit should be filled with 5oz of R134a. It is obvious that I have to use a vacuum pump for The leak I found came from a bullet piercing valve, so as soon as I found it, I replaced it right then. When the gauge provided with the vacuum pump is hooded up, adding the oil (that doesn't come with the product) and turning it on, this is the sound you will hear. I was able to reach a deep vacuum within under four minutes, which I find impressive. I checked the manifold gauge to make sure there was no leakage existing in the system. Adding Freon to the system. For me to accomplish the task, it took about 30 minutes. This product would be recommended by me to anyone in need of a vacuum pump. Better yet, the seller can include a bottle of pump oil with the order.
We made use of these gauges without any issues, however we would have appreciated having had an adapter so we could connect to a R134 tank. A threaded vent cap can not be fitted on the cast-threaded hole on a tank of oil. As I evacuated my system, I designed and built a small jig to hold the gas cap in place. Although I probably should return it, I haven't had the motivation to go dump out the vacuum oil and ship it back. Invest a little more in a better pump by spending more money. However, I was able to resolve the issue and get the evaporator repaired so that I could be able to evacuate my system and recharge my system.
It is worth noting that the kit did not include the leak detector, but since I have no need to locate leaks at the moment this is not a huge problem. drives me crazy is the fact that the standard r134 tap sold in every automotive store doesn't fit the adapters for the service hose. To top it all off, after spending more than 130 dollars on the set I will have to take the service hose to the store with hopes that I can find an appropriate learned how to use a vacuum before I got the set, so I didn't need any of the horrible instructions that came with it. A YouTube video showing how to use a vacuum would be a big help if you are a total novice.
I enjoyed the vacuum pump. It was a bit hot to the touch after 30 minutes, but this is not unusual. It was too small for the tank to hold the hose when I went to charge the system. Furthermore, I am not familiar with the size of the adapters provided. Luckily, I have a gauge set from an older model that I used to charge the display with. I feel it's a good value for the money, but having to go through the trouble of taking out two different gauge sets to fill and charge is a bit of a hassle. We would have given them a 5 star review if they had provided the correct adapters.
When I began using the machine, the blue exhaust on the front of the pump came out of the aluminum housing and will no longer tighten so that when I use the unit, the blue filter falls out instead of the exhaust. The design is very poor and cheap. That makes me wonder what else the pump may fail to do in the future. I would not recommend buying!.
However I had some difficulty installing the suction or discharge line hoses. My first connection appeared to be fine, but my second was a bit of an issue. It's possible that retrofitting connections to a railway is different from when installing an R+ The 12th A/C truck made it This is 134A. As always, a good value for the money.
It seems that the pump is working and that the gauges are working, but the hose fittings leak so badly that The yellow fill hose at the very least needs to be replaced, because the fittings leak so badly that it is almost comical. It's just cheaply made Chinese rubbish, so you end up with whatever you get.
