PEX Tubing Installation Manual

11
The SharkBite PEX tubing is design certied to ASTM F-876, F-877,
CSA B137.5 standards, and is listed to the NSF/ANSI 14 and CSA
B137.5 standards for use in potable water systems.
Since SharkBite PEX tubing will expand and contract during
temperature changes, please allow slack when running the tube
through the building. SharkBite PEX will expand and contract at a
rate of approximately 1" per 100 feet of tubing for each 10°F change
in temperature (see equation below). We recommend that offsets 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:
160 psi @ 73.4°F (23°C)
100 psi @ 180°F (80°C)
80 psi @ 200°F (93°C)
ΔL = α(L • ΔT)
where: ΔL = change of length (inches)
ΔT = change of temperature (°F)
L = original pipe length (feet)
α = coefcient of linear expansion = (8 x 10-5 @ 68°F)
Example:
ΔT = 10°F L = 100' Δ L = 0.08”
