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 15 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.
