If your printer is calibrated as well,
the thread fits well. you may need to lub it, the first time.
Depend of the printer precision, but maybe it will need
a teflon tape to make it fully airtight.
I didn't push the test more than 15 PSI, if someone want to do some crash test,
please feel free to put your feedback here.
Edit: 18/07/2016 added a Quick-disconnect plug.
