Why doesn’t the can tap fit the R-134a sealing can?

I used with zero r134a can not self sealing. Worked perfect. I looked up self sealing can and they use a 1/2 connecting instead of 1/4. This is 1/4 connect to piercing tool. I'm not sure if this piercing part will work with self sealing can by adding an adapter as it is not real long. They do make a piercing fitting for the self sealing can that will fit to the yellow hose. Then gauges will work OK. Guess need to send orion motor tech a email to say need an another adapter to order to use on self sealing cans. This is made to use in normal automotive air and home ac fittings. Fitting I s fairly cheap.

What are the extra parts in a separate bag ?

The extra parts in the separate bag are three white washers and one connector.
