Solar Flexpipe, DN 12

The established flexible pipe system for innovative house technology.
• Stainless steel
• Material AISI316L, DIN 1.4404
• Nominal pressure PN at 20°C (bar): DN12 (21), DN16 (16), DN20 and DN25 (10)

Laying: Stainless steel flexible pipe is unrolled on site. Its shape can easily be bent and corrected. The minimum bending radius must be observed. Torsion must not be applied. Cutting: The flexible tube should not be cut too short. You will need at least one wave to create the sealing surfaces. It is best to use a pipe cutter and apply it to the wave trough. Cut at a right angle with little pressure, turning the cutting wheel slowly.

Suitable for QuickFix-Pro metallically sealing screw connections.
