The advancement of industrial societies has led to a growing interest in new production methods, particularly those involving elastomeric tools. This study introduced a novel technique for creating a T-shaped fitting with two-way pressure on the tube, using a elastomeric interface. The experiments conducted on aluminium and brass tubes utilized elastomeric tools made of polyurethane and PVC. The findings demonstrated that applying secondary pressure from the outside of the tube effectively shaped the final workpiece while delaying rupture. Furthermore, careful control of factors such as axial pressure and the amount of secondary pressure proved to be crucial in preventing tube tearing and wrinkling during the process.
