hi all i have a yong heng compressor and gold filter from alie express but they do not work on my tank. fit from quick connect from filter to bottle seems to be where the leak is at do you think i need another quick connect?
Qd’S or foster fittings in this gig can be very different and not so compatible, have had the same issue with multiple hookups, the male foster containment band usually is the variable? If it’s loose and leaks? Sometimes you can use a fatter o’ring to take up the gap on the female side? Hope that might help.
Sounds that you need to either replace the connector on the gold filter side or that on the tank's side, depending on which one is easier to get. It will be better it you can post some picture showing the connector at the tanks's side.
Make sure that the leak is at where you think it is. If it is from the female brass fitting on the end of the hose, check that there are two O-rings there. If not, that may be your problem. If the fittings won't couple or the locking ring won't close all the way, replace either side until you have a safe union. Usually, if they fit together OK they will seal if the O-ring or rings aren't missing or damaged.
