In a few posts here the build up of metal "or shoulder" has been mentioned on the fill nipple. This has to be so annoying for you not so technical guys out there.
This is caused by the fill rig locking balls pushing against the nipple locking shoulder when under pressure. A short term cure for this, is to file away the offending lip of metal so the fill rig goes on. Short term is the word here, if you've been in this situation or you have a fill nipple with this lip of metal and you can't get the fill rig on, CHANGE THE WORN FILL NIPPLE ASAP
To answer your thread.
Try to understand the process of filling your bottle this will take the fear away of filling bottles, but never get lazy, compressed air is dangerous and must be handled with care.
