they don't do them, all the koolance QDC's that OC stock are here;

they do 10mm / 16mm or 13mm/16mm but not 11mm/16mm
but they do G1/4 threaded ones, so you can buy those and then use whatever G1/4 fittings you are using in the rest of your loop
edit; sorry, the G1/4 ones are all male threaded G1/4's so you'd need G1/4 couplers as well...
