Twin Way Pre Insulated Solar Hose
·Specifically designed for solarthermal panels.:
1. Each coil, it includes two parts: roof pipe and in-door pipe. Two meters' roof pipe at one end, which have excellent performance of UV-resistance ,water proof and bird peck-Protective

2. A flexible high-grade stainless steel tube 316L(or 304)

3. EPDM insulation. Work Temperature rang from -50℃ to 150℃,Max to 175℃

4. UV resistant and High mechanical resistant protective film.

5. Save money. Easy connect,no soldering required,Saves installation time,reduction costs.

6. Save space. Minimal space required for installation
