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 millimeters (1/4"-1 1/2")for tubes and between 38 and 55,7 millimeters 1 1/2"- 2") 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.
