Anyone needing an adaptor for gauges or hoses (Buy R134a to R12 tank adaptors)
Nowhere near me had the right adaptors and soon gave up and ordered a set of R-134a to R12 adaptors here on Amazon after making sure the sizes were correct. the injector and adaptors came too late to be used but now i can mount my injector to my manifold gauge for next time.I hope this helps out anyone needing this information.

Great professional tool
This is a very high quality tool for use by professionals. Very easy to use. Those that complain about the wrong fittings simply bought the wrong one. This one is for R134a, Mastercool also offers one for use with R12 systems. The fittings are different. You do have to inspect and clean out the barrel prior to first use. This injector may be used before charging a system or with a fully charged system. I own all of the Mastercool line of A/C service tools. They are the highest quality and the highest value. Don't trash this fine tool because you are not a professional and don't know how to use it.

Great Mastercool quality as usual
Been a pro for years, using Mastercool products. This oil injector does exactly what it's supposed to do, and is high quality. If you're too clumsy to thread a big lid onto a cannister without crossing it up, AND if you don't know what size fittings you need, you probably should leave this stuff to the big boys and stay out from under your hoods. Oafs and clowns.

Easy way to add product to AC system
Very good quality. The valve works and is also of high quality. The body is machined, the threads are clean. I had no trouble using this item on several auto AC systems this summer. I would recommend it to anyone who needs a way to get oil into their AC system. On one car when I didn't have my gauges with me I just used a can of 134a to push the oil into the system. Worked perfectly that way.

No vacuum required to inject dye
The instructions say to use vacuum to pull in the dye. Just rig up your lines and use Freon to shoot it in.
