Product Introduction

EverPeak supplies replacement vacuum tubes as spare parts for thermosiphon and pressurized solar collectors. Each tube is a high-borosilicate glass cylinder with an inner absorber and a selective coating for maximum solar uptake.

Tubes are individually foam-packed and palletized, making them easy to stock for distributors and installers who service existing systems. A broken tube can be replaced in minutes without draining the whole collector loop.

We offer both 47mm and 58mm diameters, with standard heat-pipe or U-pipe compatible versions to match popular collector manifolds on the market.
