316L Single and Twin Pre-insulated Flexible Solar Hose

Riwatt pre-insulated flexible solar hoses Introduction

Riwatt Pre-Insulated Flexible Solar Hose requires just one step to complete solar water heater pipe installation.
Our pre-insulated flexible stainless steel solar hose is equipped with high-temperature EPDM insulation, durable jacketing protection, and a pre-assembled 2-core temperature sensor cable—making it the ideal choice for any solar thermal system. It enables quick and reliable connections between solar collectors, the pump station, and the water tank—no welding required!
The system is lightweight, space-saving, and easy to handle, even in confined areas. Flow and return pipes are clearly marked for simple identification. The smart break-point design allows installers to separate twin pipes into two single pipes without damaging the jacketing, perfectly meeting different installation needs.
