This worked, but after one use the threaded part broke while it was hanging up to drain the excess oil out.

I've only had the chance to use it once so far, to inject some oil into an AC line, but spent some time playing with it and the adapter fittings it comes with. I can't speak to longevity, but the fit and finish for the most part shows pretty good tolerances in the manufacturing process. The only piece that could be improved is this little knurled nut that sits on the main shaft below the plunger handle, that seems to be used to limit how far the plunger will move. It's a bit useless because it's loose and doesn't stay where you set it. It works to lock the plunger in place so you can't depress it if you want, and doesn't get in the way otherwise, so it's not a major issue.The fittings are nice, and they come with a tool to adjust or install/remove the valve cores, which was already necessary the one time I used it, as the port I plugged into required the pin to be extended to actuate its release.The only thing I haven't figured out yet is an easy way to purge any air bubbles reliably besides just holding the injector and hose you've attached to it upside down and trying to depress it slowly without making a mess (which is more difficult than it sounds).
