STAUFF NRC type clamps were designed for the noise and vibration reducing installation of pipes, tubes and hoses with the most common outside diameters between 6 and 42 millimetres (for tubes) and between 38 and 55,7 millimetres (for hoses). The working principle is based on clamp bodies made from Polypropylene following the Standard and Heavy Series according to DIN 3015 with a specially shaped, two-part elastomer insert, which mechanically absorbs vibrations in the pipe, tube or hose and as a result reduces noises arising to a minimum. The insert is in particular distinguished by how little of its surface is in contact with the pipe, tube or hose and clamp body, and as a result is far more effective than the previously known solutions.
