Spring band hose clamps in accordance with DIN 3021

NORMACLAMP® FBS spring band hose clamps are the perfect choice for hose spigot systems that are exposed to significant temperature fluctuations. Once installed, their dynamic spring properties ensure an automatic re-tensioning effect over long periods of time. Even at low temperatures, this mechanism still enables sufficiently high levels of radial clamping force to be achieved, which in turn ensures excellent sealing reliability. With NORMACLAMP® FBS clamps even hoses that have a tendency to “creep” can be joined securely. Manual or pneumatic tools are used for professional installation.
