Heidelberg qm46 pneumatic leak

I have a Heidelberg qm46-2 (Print Master) with a leak coming
off a fitting attached to the pressure tank pointed out in the pic,
How is this replaced? also can't find the part# in book just the
hose #, any help greatly appreciated.
Thanks!

turns out fitting was fine, cut a 5mm of the hose plugged it back in and no leak, time for new a new hose.

 

Hi sir:
I believe the part is : 1.2-00.580.3423 Union Joint page C-66 parts book

 

it is advisable to avoid more of these same leaks to insure that you either drain the pressure tank regularly of condensation or to install an air dryer to dry the air in your pneumatic system

 

how do you drain the pressure tank? just replaced the Y-19 and was told SF 3+15 16 +- but no luck

 

Hi sir
Every 20 minutes, the condensate drain valve Y19 is
opened for 2 seconds by the electronic press control.
Please review the+24Vdc is there in terminal of Valve Y19,and tigh very well the loose cables.
If necessary, drain the entire condensation
water which has collected by opening the screw at the bottom.
