I habe 1/4 mfl swivel notes on all gas and beer lines on all my systems. I use both pin lock and ball lock so it allows me to switch easily. The last batch of pin lock qd's i got from an auction have larger ffl threads, like 5/16 i think. I have all the hoses so i have swivel nuts for them but then i cant change them out freely. So ideally i would like to find an adapter like 1/4 male to 5/16 female to adapt these new qd's to be interchangeable. cant seem to find something like that in mfl.
