35/64″ (14 mm) Oetiker Stepless Ear Clamps. 25 count. These range in size from 14 mm when open to about 11.5 mm when open
I’m a big fan of Oetiker style clamps, especially in my kegerator. See: Oetiker Stepless Clamps for Kegerator Gas and Beer Lines. FYI: 14 mm is about .55″ and 11 mm is about .43″.
