What do the ABS, PVC, CPVC, PB, and PEX plumbing pipe names mean?
Sunday, July 8, 2018
They are all plastic pipes, and the names are acronyms (abbreviations formed from the first letters of other words) for the rather long technical name of their chemical compositions—except for the last one, which is just sort of an acronym:
ABS - Acrylonitrile Butadiene Styrene
PVC - Polyvinyl Chloride
CPVC - Chlorinated Polyvinyl Chloride
PB - Polybutylene (no longer manufactured in the U.S.)
PEX - Cross-linked Polyethylene (X is for the cross-linking)
