This is an on-going problem, apparently. We were getting the coolie cap fittings from EFI but they got out of the solar business recently.<br><br>Does anyone have a source for these now?<br><br>Thanks in advance.<br><br><br clear="all">

I use similar boots, and design the penetration so the insulation and wrap ( we use aluminum) nearly cover the whole boot by the time you're all done. you're left with about 1/2" of boot showing all the way around. <br>
where can I get the coolie cap style brazed copper flashings?<br>

I use accordion style rubber boots. These are typically attached to the roofing with a bead of silicone underneath and gasketed metal roofing screws on top. These are made for all kinds of metal roof penetrations and I have even seen them used for 6" metalbestos stove flues. One note of caution, the orange "high temperature" ones are (I think) rated only to 180 degrees F. so you want to make sure the SHW fluid never exceeds this. Also in time, like any rubber flashing on a roof the rubber will deteriorate from UV. I build a show shed over my system's plumbing which shades it so hopefully this will not be in issue in ~20 years.<br>

Any thoughts on how to flash a copper pipe roof penetration on a metal roof. The brazed copper flashing we typically use would cause corrosion with the steel roof I'm afraid. WHat have others used in this situation?<br>
