5/16 inch barbed x 1/4 inch flared female nuts provide a perfect coupling for your beverage lines. This size works great with Ultraflex 5/16 inch tubing or braided gas tubing. Made from stainless steel.
A Nylon Flare Washer (not included) will be needed anywhere a metal to metal connection is made (such as onto a gas distribution manifold). These are not needed when connecting to keg disconnects, these have a plastic tip already.
