Might have a helpful hint. If you need to get into tight little nooks & crannies. Take the stem fitting used to fill basket/socker balls and file the tip off and "round out" the hole. Depending on your handnozzle type,unscrew the tip and the "stem" should slide in and fit perfect (might have to file the edges if it has a nut style thread and shorten up the threads a bit,to fit),careful so the stem don't slide into the hand piece. Mine does,but pops right back up with air pressure. That add-on long stem will get you into tight places and better pressure to BLAST out almost anything. Great for blowing dust off iron sights too.
