Excellent tubes!

Amazing quality, fast delivery. Highly recommended vendor for 58mm x 500mm evacuated tubes. Please consider stocking the 58mm x 1800mm tubes. You might find a lot of your customers are ready to "graduate" on to the next size up for their projects.

I ordered these tubes a few months ago for a solar steam engine system I'm designing. They're perfect for prototyping this project. I was able to boil water in 5 minutes by focusing a fresnel lens on it. I was expecting the pipe to explode from the focused heat, but it held up fine.

Bought 20 tubes and UPS decided to destroy 1 box for me. Mike was great and shipped a fresh box asap. Super fast replies to emails and a pleasure to work with. Highly recommended

Finally you have a reliable U.S. source for high-grade solar vacuum tubes, also known as solar evacuated tubes. Unlike many solar vacuum tube suppliers we offer a standard 100% shipping protection guarantee. Make sure other vacuum tube suppliers you are considering offer this type of no-questions guarantee for these fragile evacuated tubes. We offer excellent customer service for any assistance you many need for your solar hot water system needs, and stand firmly behind the quality of all our products.

Each solar evacuated tube soaks up the energy in sunlight, absorbing it into the super-insulated inner tube of their incredible double-wall heating system. Once inside, the heat of the sunlight is trapped inside the inner wall of the inner glass tube, creating a powerful solar thermal collector. Highly-reflective layers of steel, aluminum, and copper trap the infra-red energy of the sunlight, and the nearly perfect vacuum between the inner wall and the outer transparent wall protect the inner tube from heat loss due to convection, just like a high-grade drink thermos. This thermos effect can quickly heat water to boiling temperatures in direct sunlight, and keep the water well over 100 degrees, even over night! Perfect for you DIY, home improvement, solar hot water heater.
