XtremepowerUS 3CFM 1/4HP Vacuum Pump HVAC R134a, R12, R22, R410a, A/C Refrigeration R134 Can Tap Adapter, R134 Quick Connector AC Manifold Gauge Air Conditioner Oil Bottle w/Bag

Great vacuum pump! I had no issues assembling the system with absolutely zero tools required. If you are purchasing this or other vacuum pumps for evacuating AC lines on Mini-Split systems like I did, make sure to grab a 1/4 to 5/16 adapter fitting. These are cheap and easy to grab, but all pumps come with the 1/4 fittings and they do not work on the evacuation port. I assembled my unit and had to order the fitting (next day shipping for the win) and after connecting the fittings I pulled a vacuum and closed the valves to let the system set. 4 hours later, even with the manifold in the vacuum loop, I had no visible drift, and that was with all the fittings finger tight. I was using a precharged outdoor unit, so no refrigerant was added.

Worked great! Finally got my AC working after 7 years. Would recommend this to anyone and will gladly use it again. Nice and quiet, and surprisingly simple to use. Comes with a travel bag to keep it organized. Go watch the ChrisFix video on vacuuming your AC system and have yours done in a couple hours. PS, if you have a leak in your system you can use this set to find it, just apply compressed air to the yellow tube with the gauges open, and while reading a positive pressure on the gauges, close the system and spray soapy water on your lines and hoses.

The tool as a whole worked well. The reason I didn't give it 5 stars is because of the can tap attachment. As you may have read on other reviews, it doesn't fit the yellow hose directly, the fitting was hard to turn to pierce the can and no freon would release even using the adapter to the can tap which I didn't anticipated i needed to use. I thought connecting the hose to the can tap was all needed just like you would with those individual low pressure lines you use to put in freon. The deal is the size of the tap included has a 1/2" connector instead of 1/4" which is the size that fits the yellow hose. I had to buy myself that size can tap to accept the hose and was made differently internally that the freon flowed freely and I could use the rest of the equipment then. It's a good set, just need to include a easier to turn valve can tap with 1/4" connector to get a 5 star rating in my opinion.

This is great, good price all you need to work on Any type of AC problem.

This works great for someone who doesn't want to pay a shop to charge your AC. It saved a ton of money after I swapped the compressor on my truck recently. So far It will do anything I may need to do for years to come as a DYI'er. The pump might be a bit louder than a snapon one but not super noisey.

Used this pump on my mini split, works perfect. Nice kit

I have had this for a year. I have used it many times. Vaccuum pump works great. Gauge set is average but work very good. After a year I have changed a couple hose gaskets, ( $3). All of it fits into one bag and it is very convient. I recommend this for everyone who needs a charging set.

Work great pulled vacuum in no time at all but I did have to have separate fittings for a mini split.
