The better connection guaranteed 

For over 70 years, the NORMA Group has been synonymous with innovative connection solutions in the automotive industry. Our original equipment parts impress with reliability and material durability, even under demanding conditions. In addition, our well-thought-out products are easy and quick to assemble.

As inconspicuous as connecting parts like hose clamps in a vehicle may be, their failure due to inferior quality can lead to potentially serious consequences. Did you know that up to 100 connection points in a vehicle must be permanently and securely connected? It's worth relying on proven quality products in such cases.





OE Parts Guarantee Safety

For many decades, the automotive industry has relied on the products of the NORMA Group; 90% of all European automakers use our fastening and connection solutions. Many of these original equipment (OE) vehicle components are available in the automotive parts trade as original replacement parts for independent workshops.

Because it's certain: Only with original parts specifically developed for a particular vehicle can quality and safety be ensured in all connections during repairs. OE parts stand for precision, easy assembly, and top-notch quality.
