Loose connection/leakage between Coupler and Beer Line
I bought an Edgestar KC2000 kegerator off FB marketplace. At first i was having issues with beer leaking through the top part of the beer line handle (picture 1) and then saw online that there should be a black coupling washer there. After this i bought the couplers and put them in and now the leakeage is coming from the base/insert screw-on location (picture 2)….
Ive tried experimenting with everything and have tried tightening with 100% force hand tightening. Is this user error, are there other pieces missing, or is this just fault equipment? Or do i need a tool to turn the screw on connection even tighter?
