And here's the chart for clarity. @AndreZA has posted several times. You can see the brush side of all the qd's will clip in to any qd. My favorite setup is to run a badger non-coiled poly hose w adapter to standard 1/8th and a qd. Just bc the badger hose is teeny and it's like it's not there. Mine happens to be hot pink one from an early 90s badger 350 set which is also hard to trip over.
