I love this business. Allows you to charge your system without having to carry around an entire manifold and two more hoses than necessary. If you already have scales, coolant, manifolds, etc., you'll probably just say it's "just a valve core". I carry this little thing in a special coolant backpack, hose, fluid charger and tiny Bluetooth sensors. All this stuff in a backpack leaves my hands free to zoom or whatever. It wouldn't be possible without this little thing and it's better than those little brass tees because you don't need a wrench, it doesn't leak and it's Appion quality.
