The KT85-MFL is the ideal coupler for anyone who wants to easily switch back and forth from domestic to home brew kegs. It features 1/4" MFL fittings for both the gas in and beer out, so you don't have to worry about pulling a hose off of a hose nipple or removing clamps if you want to use a different type of coupler. Simply unscrew the nut from the fitting and screw it onto comparable ball lock or pin lock couplers.
