The coolie caps are really just regular (oversized) caps which have been
punched out to snugly accommodate the pipe to be sealed. Tom Lane's book,
Solar
over the end of
the vent, the loop of pipe, common with SDHW does not allow that luxury.

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.
Does anyone have a source for these now?
Thanks in advance.

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.
where can I get the coolie cap style brazed copper flashings?

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
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?
