Fascetta a molla pretensionata • Ø 18 mm

Pre-tensioned spring clamp made of corrosion-protected C75S spring steel, clamping force 200-250 Nm.
Ideal for drinking water pipes with an outside diameter of Ø 18 mm.
Due to the pre-tensioning, no pliers are required to tighten the clamp on the pipe:
once it is in position, simply unlock the snap mechanism with the special tool (Code FST500) and it will tighten automatically.
To re-open the clamp after the first application, the use of the pliers (Code FST600) is indispensable.
