Great 1234YF die!

As everyone has stated the can has a standard 134a puncture top that works as usual (not the reverse thread self sealing top). The charge was large enough to actuate my compressor and the color was bright green. So far no leaks. The price was also great and the shipping fast. I’d definitely order again.
