Tube beading is a tube end forming process that creates a bead on the end of a tube. It is the most popular end-forming type. Tube beads can be used to help hold a hose on the end of a tube or to increase the strength of the tubing, or be used for O-rings. It is often used for products that require a slip-on hose connection. The principle is to leave a small gap open in-between a clamp that holds one end and a tube forming die that supports the other end. As the two tools hit their end point, the tube collapses at the gap creating the bead. Slightly adjusting the distance of compression can change the beading width. Usually, the beading height has to be over the wall thickness. Otherwise, it is very hard to create the shape.
