Product Description ▼
The NORMACLAMP® FBS spring band clamp is the ideal solution for hose-nozzle systems that are exposed to strong temperature fluctuations. Thanks to its dynamic spring property, it offers a continuous, automatic retightening effect after mounting – even at low temperatures, a sufficiently high radial clamping force is achieved, ensuring high sealing reliability.
The one-piece, screwless hose clamp made of spring steel C 75 S with a zinc-containing coating without chrome VI impresses with its even clamping force distribution and optimal roundness. Even hoses that tend to "flow away" are securely and permanently connected with the NORMACLAMP® FBS.
- Dynamic retightening effect – automatic retightening after mounting
- High sealing reliability – sufficiently high clamping force even at low temperatures
- One-piece, screwless design – easy and quick assembly
- Even clamping force distribution and optimal roundness
- Temperature resistance from –40 °C to +200 °C
- Clear traceability through batch numbering
- Visual control of nominal diameters through color coding
- Corrosion protection from 480 hours in salt spray test (C 75 S)
- Cooling and heating water circuits
- Fuel circuit
- Air guidance
- Water and lye drainage pipes
- Wherever hoses are exposed to strong temperature fluctuations or tend to "flow away"
