M25/DN20 Solar stainless steel flextube Material AISI316L

The flexible, insulated Solar Flex Hose is the proven solution for innovative building technology and photovoltaic applications in outdoor areas.
Made from corrosion-resistant stainless steel of grade AISI 316L (DIN 1.4404), this hose offers excellent corrosion resistance and durability under extreme conditions. Thanks to its open, corrugated design, it is particularly flexible and easy to install. The elastomeric rubber insulation also provides reliable protection against UV radiation, ozone, and moisture, making it ideal for use in photovoltaic systems.

The hose is designed for various nominal pressures at 20°C: DN12 withstands a pressure of 21 bar, DN16 withstands 16 bar, and the DN20 and DN25 variants are suitable for 10 bar. With a wide temperature range from -270 °C to 600 °C, it can be reliably used even under extreme conditions.

The installation of the stainless steel flex hose is particularly user-friendly: it can be easily unrolled on-site, bent into the desired shape, and adjusted as needed. It is important to observe the minimum bending radius and avoid torsion to maintain the optimal functionality of the hose. When cutting, the flex hose should not be cut too short; at least one wave is needed to create the sealing surfaces. A pipe cutter, applied at the trough of the corrugation, is ideal for precise cuts. With minimal pressure at a right angle and slow adjustment of the cutting wheel, a clean and safe cut edge is achieved.

This insulated stainless steel hose is perfect for wiring and protecting components in photovoltaic systems, especially in outdoor applications. Its high mechanical load capacity, temperature resistance, and easy installation make it a durable and reliable solution for long-term use in various outdoor applications. With this hose, you maximize the efficiency and reliability of your photovoltaic system and benefit from a robust, low-maintenance product.
