What type of Teflon for headers?

[Rcmaster199 at aol.com]

You are correct John. You can find low density polyethylene tubing in homes, 
as overflow tubing for water softeners for example. Nylon tubing is also used 
in a variety of applications in the home. However, most of the remainder 
piping is poly vinyl chroride or PVC for short, including the piping for hot water.

Perfluorinated polymers such as FEP, PFA or PTFE (all Teflons, BTW) will 
practically never find their way in regular homes, due to expense primarily. They 
are very high performance materials used in extreme environments. Hot water is 
an inocuous application for PTFE, but steam, highly corrosive and hot 
chemicals, 
and many petroleum based chemicals including most fuels
, would be typical applications.
