Overview

Caleffi SolarFlex NA3540-15 pipe is a flexible, quick installation system to connect solar collectors to a pump station and then to the storage tank. The SolarFlex pipe system is easy to install, enabling pipes to be run without using a torch in confined spaces or on the roof. Two closed cell elastomeric foam extrusions of high temperature resistant EPDM are protected against damages by a common outer cover. Flow and return pipes can be easily separated without damaging the insulation.

This is a special order and will take extra time for production and may ship directly from the manafacturer.

Caleffi SolarFlex is the way to reduce installation time while ensuring a leak-free installation. SolarFlex's union nut assembly method does not require special tools or time.
