Tubes and hoses are custom designed and produced using heat and special tooling. Many applications that involve multiple sections of tubing or hose, along with fittings and clamps to make connections, can benefit from this customization. Heat-formed shapes eliminate extra fittings and clamps, their potential for leaks, and their inventory. With a heat-formed shape, only one part is needed instead of separate pieces that must bend around or through other equipment and machinery. Turns and twists can cause some tubing and hose to kink, thereby cutting off fluid or air flow. A formed piece that’s custom made for a specific use greatly reduces the risk of kinking and flow impediment. Heat-formed shapes also ease and speed installations because there are fewer connections to make. A wide variety of shapes are possible, from single elbows and curves to parts involving coiled sections, flared ends, and multiple twists and bends. Materials that can be heat formed include PVC, polyurethane, nylon, and other thermoplastics. Both unreinforced tubing and braid reinforced hose may be used.
