BACOENG 3CFM Vacuum Pump & Manifold Gauge Set - HVAC A/C Refrigeration Kit - Diagnostic R32 R134a R410A R407C

Works great! I'm not a professional mechanic, so I don't know how long this thing will last, but for my purposes, it's great. I retro fitted my R134a ac system and I didn't' need any adapters with this unit. Took minutes to set everything up. The fittings were of very high quality. They fit tightly with no leaks and no wobble. The gauges are also very high quality with high visibility numbers on a large face and a very large range (including negative for pulling vacuum). Hoses were also sturdy and very long and can reach fittings with 2-3 feet to spare when hanging the gauge set on the hood latch. This set is worth way more than I paid for it. Very pleased with this purchase, and you can't beat the price!

Vacuumed and regased my car with this, i work on a few project cars a year so thought i'd try it.Did the job perfectly, i doubt it would stand upto professional every day use, but certainly good enough for a weekend warrior like myself.

Easy to use. Although booklet is not very good

This is an excellent quality manifold gauge and vacuum pump. Well worth paying the extra money rather than going for the cheaper versions.

As a user of these pumps in the past its important to note that some people have reported smoke coming from the pump, this is normal for 1st use.Its also residual gas from the A/C system being drawn out and moisture vapor, however this should stop after the 1st use (smoke, not the gas) and shouldn't last long, for example, when i 1st hooked this up to my car is smoked lightly for around 5 minutes, since then the unit has not smoked, eg after hooking it up to the missus car i got no smoke at all, however i did get some vapor and her system was empty the same as mine.If your system if not empty you wont use the pump though, you will just use the manifold gauges to top your system up.

The manufacturer storage box is too small and inappropriate for the contents. Once opened the box is very difficult to close and you have to force the lid down to close the clasps. It was like trying to pack an over filled suitcase! The hoses are crammed in along with the safety glasses and as a result the safety glasses were broken in the box when I opened it. Also the separate connector tap for connecting to smaller air conditioning bottles was loose and rattling around and had badly scratched the surface of the control valve knob on the manifold. The "Open and Close", writing was barely legible making it difficult to read.Overall, this could have been a half decent set if they fixed out these simple niggles. Another inch or two added to the storage box thickness dimensions would have made all the difference. And a better way of securing the items inside is needed.

Easy to use and done the job well

Very good tool to check for leak and recharge the AC, the bad point is the sealing on the hoses are not a good quality ones
