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

Good deal, works great, easy to use .

Used twice, worked as I expected.

DOES NOT INCLUDE 5/16 MINI SPLIT ADAPTER This kit is GREAT and works very well for a fantastic price. The gauges are clear and easy to read. The hoses are high quality, as are the included adapters. I can't comment on the r134a puncture valve, I haven't tried that just yet. It's pretty quiet, it's not the fastest at 3cfm but for something like a mini split or home AC it's more than fast enough. I let it run until all indication of air in the line stops (bubbles or burbling sounds) and then an extra 5 mins to make sure. Easy squeezy and for the price, I don't know that you can beat it--even at Hazard Fraught. As someone else said, the little cap for the oil port is very easy to lose...but whatever. I bought this to install a TOSOT 18,000 BTU Mini-Split, but you could use it for anything needing vacuum. The video I followed to install my unit suggested this vacuum pump and indicated it included "all gauges and adapters", and this turned out to be incorrect. My ONLY beef with this item is that, as far as I can tell, NOWHERE does it list what size adapters are included. I wish that I could tell you what they ARE, but I can't, I don't know. I know that the standard mini-split 5/16" is NOT in the box. 5/16 Inch Female Quick Coupler to 1/4 Inch Male Flare is the adapter you'll need for a mini split. There are lots of options, the one I ordered was $7 and came in two days and fit perfectly. Pulled to -30 psi in seconds and cleared the lines totally within 5 or so minutes, then I let it run for a total of almost 20 minutes.

Works great! FYI the cheap Walmart 134a cans don't like to screw on tight to the fill hose adapter. Everything on this manifold set works as it should.

Using this I was able to fix AC in my car. Fantastic.

So the longevity question has been answered! THIS is a quality setup! Maybe not the fastest or the best, but sure as heck does just as good of a job as anything else costing more. I've used mine to add 134A to leaking systems, repair systems, and have it hanging always within reach in my garage. I use the standard small cans of 134A and I can't tell you how many I have used through this manifold. I love it. I recommend it. The vacuum pump works GREAT! Will vacuum down the system perfectly! The bag is very nice as it protects the vacuum pump from dust and grit and damage sitting on the shelf. What is even more wild, to me, is that the price has gone DOWN since I bought mine! Wild! Seriously, for the shade tree mechanic, backyard mechanic, or even a mechanic in a shop, I can confidently recommend this particular kit as being a good buy. I literally just saved a $2500 dealer repair bill for my wifes AC by doing it myself with less than $400 in lifetime warranty parts! YouTube can show you how to use it! This setup cost less than the $159 diagnosis fee I ended up having to pay! Get you one!

Very good bargain , used this to diagnose the A.C system on my car . It is easy to setup, and isn't to loud . Comes with all the hardware you need to start diagnosing your a.c system .

Decided to install mini split in our fifth wheel and need a vacuum pump to do it. This pump was straightforward and had plenty of power, definitely felt solid and of good quality. The gauges worked as the should and my first mini split install was a complete success! I can definitely recommend this product!

A mi padre le entro el interes por aprender a darle mantenimiento a los aires acondicionado e investigue los equipos que podrian facilitar su aprendizaje y poder utilizarlos en casa, este es el ideal, le encano y funciono muy bien, hoy por hoy el se encarga de los mantenimiento de los aires acondicionado en su casa y en la mia :D

fonctionne trais bien j'utilise régulièrement je la recommande

I tried to change pump and condenser without a vacuum pump. Worked for about 15 mins, then vapor locked. Put on the pump and ran it 2 hours, had air since. What's not to like?

facile à brancher, fonctionne bien

Worked well
