Very good tool to own if you're DIY'ing your A/C work. Great way to add dye to the system to chase leaks with.

Exactly what I needed to add to my home ac repair business now I am able to add oil into system with out having to fill the filler hose with oil a lot faster I just had to get adapters to be able to hook up tommy guages

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.
