Opinions on this vacuum pump

CyFi on Mon July 28, 2008 7:32 PM User is offline

I would love if you guys could take a look at this vacuum pump and give me your input on it. I need to get my system evacuated and it is costing about $70 to get it done, and thiis vacuum pump is basically the same price. I would much rather do it myself, and if it lasted once, it would have paid for itself. Do you think it is enough to pull a deep vacuum and help get rid of moisture in the system? Thanks again.

Another question i had that was unrelated. I am buying an r12 manifold gauge set with r134a adapters on the lines, but my question is, if i want to use a can tap to charge the 134a, how do i connect it? All the gauge sets i have seen have a screw on type center inlet, and all the can taps i have seen have a quick connect outlet, so would i need to buy a 134a conversion kit and put the adapter onto the manifold set itself so the quick connect can be attached to it? Thanks for the help./

Please respect the Hosts site by not posting links to other tool sites, that is kinda like slapping him in the face..If you go to the sponsors site you will find side can taps.. But for the record, most harbor freight ac tools are not quality, especially manifold sets.. Hope this helps..

sorry, i didnt realise this fact.

On topic, i am sort of confused. Why would you tap into the side of the can to fill, why not use the top of the can with the threads that are already there and the puncture spot? Are the threads on the manifold gauge set the same as those of an r12 fill port? If so could i just put a conversion fitting onto the center of the gauge set and use my can tap that i already have that has a quick connect for r134a ports? Also, how do i fill properly with a side tap, how high on the can to i tap and how do i properly fill as a gas? Thanks. Are there any can taps that use the pre-existing tap port on top that screw onto the manifold gauges?

A side can tap takes both R12 and r134a cans, and has both fittings, just very handy when using cans.. They also sell adaptors for the R12 gauges, not sure what brand you have.. But check out Side can tap

also look for the adaptor you need here here at ackits.com mastercool tools

I may have come down a little hard on you and I apologize, we all want to save a few bucks, but when I see harbor freight tools I think of working on an engine with rubber wrenches.. We often here of their hoses blowing out even with the rating on the side of them.. Some things can be dangerous, and AC work leaves no room for short cuts..Just my opinion..

Top can taps for R-134a have acme 1/2 threads, same as a R-134a vacuum pump. So the adapter that comes with a combination gauge manifold should fit them. It's really worth it to invest in some decent quality tools; they will always work properly, last a long time, and still pay for themselves in very few uses.
