Spring band clamps

W.TEC^®FBS - spring band clamps for the industrial sector

Hose-tube connections are often fastened with fixed clamps, referred to as hose clamps. Irrespective of the design of the clamp, e.g. worm drive hose clamps for screwing or ear clamps for clamping, a fixed force is transferred to the hose. However, this force changes because of vibrations and temperature changes: with increasing coldness, the connection becomes looser and untight; with increasing heat, the connection becomes tighter and damages the hose.

However, spring band clamps are self-tightening fasteners for hose-support combinations. Due to the use of tempered spring band steel, they have a very high degree of flexibility. They therefore continually adapt to the changing properties (changing operating temperatures and pressure ratios) of the hose and support. With a virtually consistent clamping force, spring band clamps ensure a constant, leak-free sealing without any damage to the hose or support. The large number of different assembly and locking variants ensures a maximum number of possible applications.

Why spring band clamps?

• High flexibility
  Continuous adaptation to the changing properties of the hose and supports thanks to the use of tempered spring band steel
• Constant, even clamping force
  Constant, leak-free sealing between -40°C and 210°C without any damage to the hose-support connection
• Easy, quick and reliable assembly
  Assembly time reduced even further thanks to the use of spring band clamps with handy clip
• No maintenance required
  No subsequent re-tightening of the connection required
• Environmentally-friendly surface protection
  Chrome (VI)-free zinc flake surface with exceptional resistance to chemicals and corrosion
• Can be reused
  Spring force does not diminish when used several times
