Product DescriptionPEX pipe works in a wide variety of heating and
plumbing applications, offering major benefits including cost
savings. In the decades following the introduction of PEX,
manufacturers developed a variation of PEX that includes a layer of
aluminum. PEX-Aluminum-PEX, generally referred to as
PEX-AL-PEX or PAP, contains an aluminum layer between two layers of
PEX. It can frequently be identified by its orange color.
The aluminum gives the pipe added rigidity and shape
retention. Since the aluminum creates a natural oxygen
barrier, PEX-AL-PEX is a natural choice for hydronic space heating
applications (including baseboards and radiant heat). Most
PEX-AL-PEX is not code-approved for use with potable water.
The lack of an external EVOH oxygen barrier means that the
pipe does not require a non-friction layer to prevent noise in
joist installations. PEX-AL-PEX provides several other
advantages. Its larger inside diameter than standard PEX
causes less of a reduction in flow. PEX-AL-PEX normally has
higher temperature and pressure ratings than standard PEX, allowing
it to perform in a wider variety of jobs. Linear expansion,
often overlooked, is another area in which PEX-AL-PEX excels.
PEX-AL-PEX expands linearly significantly less than standard
PEX as the fluid inside heats up. Its expansion coefficient
is closer to that of copper pipe. Options for PEX-AL-PEX
fittings include compression assemblies and PEX-AL-PEX press
fittings. Prior to making connections, PEX-AL-PEX must be
prepped with a chamfering tool of the appropriate size. The
tool creates a beveled edge and allows the fitting to set
properly. Product NamePex Al Pex PipeColorNatural /
