Noise and Vibration Reducing NRC Clamps


STAUFF NRC type clamps were designed for the noise and vibration reducing installation of pipes and tubes with the most common outside diameters between 6 and 42 mm and ¼ to 1 ½ inch respectively.

The working principle is based on clamp bodies made from Polypropylene (colour: black) following the Standard Series according to DIN 3015 (part 1) with a specially shaped, two-part elastomer insert, which mechanically absorbs vibrations in the pipe 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 and clamp body, and as a result is far more effective than the previously known solutions.

The tongue-groove contour of the insert and body, which is reversed and thus diverges from DIN 3015, enables the system to be used for the widest possible range of pipe diameters per clamp size, which contributes to flexibility and versatility.

STAUFF NRC Clamps are completely compatible with the commonly used steel and stainless steel mounting hardware, and if necessary can simply be replaced or retrofitted.

STAUFF also provides an alternative version especially for use in safety-critical areas, which is made completely out of flame resistant materials according to international standards and directives, and meets the demanding requirements with regards to preventive fire protection.

Main Benefits of Noise and Vibration Reducing NRC Clamps

Mobile and stationary machines in harbour and loading areas as well as municipal and commercial vehicles

  • Reducing the overall level of noise emissions,
    especially in urban areasƒ
  • Improving occupational health and safety
  • Contributing to build machinery that conforms to the
    Machinery Directive 2006/42/EC and the Outdoor Directive
    2000/14/EC of the European Parliament and of the Council

Civil shipping, i.e. on cruise ships as well as yachts and sport boats

  • Maximising flexibility with the design, layout and positioning
    of noise-intensive pipes and tubes (e.g. in close proximity to
    cabins or crew quarters)
  • Making a great contribution to comfort and facilitating
    communication on board(e.g. for engine and control rooms)
  • Reducing of underwater noise in order to protect the
    maritime environment
