The clamps we use on our keg tubing kits. No.145 fits 3/16" and 1/4" ID beverage tubing/barbs.
Stainless steel ear clamps are easy to install, and securely grip hose without damaging it. There are no steps or gaps inside the clamp; once installed, the entire inner band of the clamp is smooth. These clamps adapt to hose expansion and contraction; there is no need to retighten the clamps after installation. Requires a Oetiker clamper for installation and removal.
