Is Poly B the same as Kitec?
The straight answer
No. Kitec is a plastic-aluminum composite pipe from a later era with its own separate class action. The problems, eras, and legal histories are different.
The longer version
No, and conflating them muddies both stories. Kitec is a plastic-aluminum composite from a later era with its own failure mode and its own class action. Poly B is a single-wall grey plastic pipe from 1978 to 1998. The basics chapter sorts out all the lookalikes, including early PEX.
