About NORMA Group: A Legacy of Precision Joining Technology

Few names in the world of engineered joining technology carry the weight and credibility of NORMA Group. Headquartered in Maintal, Germany, the company traces its roots back to 1949 with the founding of Rasmussen GmbH — a business built on the principle that a reliable, well-engineered clamp is a critical safety component, not an afterthought. NORMA Group officially came into existence in 2006 through the merger of Rasmussen GmbH and the ABA Group, combining decades of European engineering excellence into a single global powerhouse.

NORMA Group is a German manufacturer of machine joining components such as hose couplings, clamps, and quick connectors. The company's products are used in industries such as automotive, aviation, construction, and shipping, and for purposes such as cooling, emission outputs, hoses, water pipes, and sterile pharmaceuticals production. That breadth of application is a testament to how deeply NORMA's engineering philosophy has penetrated modern industry.

Engineering Excellence Across Every Clamp

NORMA is synonymous with expertise and innovation, combining the right balance of technology and customer specificity, and has earned a well-deserved reputation for superior technical and innovative solutions over the decades. Whether in a professional workshop or on an original equipment manufacturer's assembly line, NORMA products set the standard for performance and dependability.

At the heart of the NORMA lineup is the iconic TORRO® worm-drive hose clamp. The TORRO® hose clamp has been NORMA's bestseller for over 50 years and, thanks to continuous further development, still sets the standard for modern clamp designs — widely used as original equipment by leading automobile manufacturers and popular with automotive professionals in the aftermarket. For technicians sourcing hose clamps that deliver consistent clamping force and long-term sealing reliability, NORMA's TORRO® range is a benchmark choice.

NORMA's product family spans worm drive hose clamps, heavy duty clamps, quick release clamps, retaining clamps, one-piece clamps, ear clips, infrastructure connectors, compression fittings, pipe clamps, banding systems, fixing clips and straps, mounting elements, and plastic fittings — a remarkably complete portfolio for anyone working in automotive repair or vehicle maintenance.

Exhaust and Specialized Clamping Solutions

Beyond standard fluid-line connections, NORMA is equally at home in high-heat exhaust applications. NORMA's product range includes exhaust connectors alongside hose clamps, spring band clamps, one-piece clamps, pipe couplings, retaining clips, and cable ties, making it a one-stop source for workshops tackling a wide variety of clamping challenges. For anyone replacing or repairing exhaust systems, NORMA's exhaust muffler clamps bring the same German-engineered precision to high-temperature environments that their hose clamps have delivered for generations.

Quality You Can Depend On

NORMA products are designed, produced, and delivered within the framework of a certified quality management system, and their innovative yet robust product designs make NORMA a household name that stands for cutting-edge safety, reliability, and performance. Whether you are sourcing hose clamps for a cooling system repair, tackling an exhaust job, or stocking a professional workshop, NORMA Group delivers the precision and consistency that demanding applications require.
