In the early days, fitting exhaust pipes was a challenging task that many shops struggled to manage. Mechanics had to manually cut and weld pipe sections, making small bends by hand. Recognizing this difficulty, Huth revolutionized the industry in 1958 by developing the first prototype of the portable pipe bender. This innovation quickly gained traction, and Huth began supplying these benders to shops nationwide. Over the past 50 years, Huth Benders has maintained its leadership in the field through continuous research and development, a steadfast commitment to quality, and an ability to adapt to the evolving needs of the industry.
