Installing SharkBite PEX-A Pipe in Concrete
SharkBite PEX pipe can be submerged in concrete, but we recommend following these guidelines to ensure a
long-lasting, maintenance-free installation.
y Protect the pipe with non-metallic sleeves when
entering or exiting the concrete slab. A larger
diameter piece of SharkBite PEX also works well in
this application.
y Do not allow joints within the slab. Use a
continuous length of SharkBite PEX within the
slab and be sure to check for leaks before pouring
concrete.
Proper Support of
SharkBite
®
PEX-A Pipe
SharkBite PEX must be properly supported to protect against excessive strain. For both vertical and horizontal
applications we recommend the pipe be supported every 32 inches between supports, leaving a little slack
(1/8-1/4 inch) in the pipe to allow for normal expansion and contraction. Always use approved PEX supports,
and never use a support that has sharp edges.

Cross-linking Methods
Cross-linking is a process that changes the chemical
structure of high density polyethylene used to make
PEX pipe so that the polymer chains are connected
to each other in a three-dimensional net by chemical
bonds. PEX-A, -B and -C are terms used to describe
the dierent manufacturing methods used to
produce PEX pipe.
Regardless of which manufacturing method is
used, all PEX pipe meet the same standards for
commercial and residential plumbing applications.

Thermal Expansion
Since SharkBite PEX pipe will expand and contract
during temperature changes, please allow slack when
running the pipe through the building. SharkBite PEX will
expand and contract at a rate of approximately 1 inch
per 100 feet of pipe for each 10°F change in temperature
(see equation below). We recommend that osets and
expansion loops be used as ways to compensate for
expansion and contraction. The change of pipe length
due to temperature increase can be calculated as follows:
ΔL = α(L • ΔT)
where: ΔL = change of length (inches)
ΔT = change of temperature (°F)
L = original pipe length (feet)
α = coecient of linear expansion = (8 x 10-5 @ 68°F)
Example:
ΔT = 10°F L = 100’ Δ L = 0.08"
