CMBecker shank fittings are specifically designed for CMBecker shanks, especially the shanks for Flow Control Faucets. What is unique about these CMB K2 fittings is that they seal in two places and provide a superior seal to conventional beer tailpieces and nuts. These will not fit conventional shanks. If you have any questions about these fittings feel free to reach out to us using help@kegconnection.com
