I have 2 broken tubes on my thermosyphon system. I am looking for 58mm x 1800mm tubes. They seem to be as rare as hen's teeth here in the US. Does anyone know of a place that I can get a few, or does anyone have any I could purchase?

Thanks. I have looked all over the past few days. I saw the SiliconSolar ones, but like you said, out of stock. The ones in Aus. are a good deal, it just may be a little far for me to go pick up. :)
