Ball Lock Post Adapters
thingiverse
I use this setup to keep my kegerator (keezer) beer lines sparkling clean using an aquarium pump. The basic idea is to connect your taps and QDs in a series so you can pump cleaner through all the taps at once and circulate it back. *Note:* this trick only works for Perlick-type faucets, if you have a plunger on the front of the tap it will not work and you'll make a mess. I was inspired by the jumper post from Brewhardware.com (https://www.brewhardware.com/product_p/ball_lock_jumperpost.htm).
