CLAMPS - CONSTANT TENSION BANDS - 12mm Band Width, FBS Style

Product Description

Constant Tension Band Clamps are one-piece, self-adjusting 12mm spring band clamps made from modified Ck75, in nominal diameters from 13 to 80mm in different gradations. They provide a quick, secure and maintenance-free connection for hoses which are subjected to large fluctuations in temperature or which tend to "slip away" under the pressure of the clamp. Their band edges are rounded for hose protection, and for additional protection against corrosion they are also available with or without organic/inorganic coating.

*Note: Special Installation tools are available. Please contact EFC International for more information.

Features & Benefits

When the temperature rises and the hose diameter increases, FBS Style, springband clamps adjust and adapt. The opposite occurs when the temperature falls. When the hose diameter decreases, the Constant Tension Band Clamps automatically re-tighten to maintain their clamping force and guarantee a perfect sealing of the interface. These clamps were developed for use in cooling and heating systems, fuel vent lines and air duct systems for the automotive original equipment market (OEM). They are now successfully used in an expansive range of industries.
