NORMACLAMP® FBS Springband Hose Clips to DIN 3021 are particularly suitable for use with hose-spigot joints which are submitted to extreme temperature changes.

Lot number stamped on clamp band = safe retraceability

Organic / inorganic coating = optimal protection against corrosion

Coating in different colour = improved engine design

NORMA® Logo = the visible sign for high quality

NW stamped on the clamp = prevention of mistakes

Special design = uniform distribution of clamping forces and optimal roundness

Round band edges = optimal hose protection

Because of their design, NORMACLAMP® FBS springband hose clips are particularly suitable for use with hose-spigot connections which are submitted to extreme temperature changes. Once assembled NORMACLAMP® FBS provide a continuously readjusting dynamic tightening effect.


Also at low temperatures the radially acting tightening force is suffi cient to assure a reliable tightness of the system.Even hoses that are submitted to extreme temperature cycles, or those with a tendency to “creep” can be combined to form a safe connection when NORMACLAMP® FBS are used.


Short description:
• Dynamic hose clip
• Band material C75S
• Coating contains zinc - chromium VI-free
• Nominal diameter from 13 up to 80 mm - different gradations



Expanding hose diameter
FBS adapting to the hose


Reduced hose diameter
FBS is re-tightening
Consistent clamping force
Perfect tightness of the joint
