PEX Pipe Basics
Recognize Minimum Bending Radius Guidelines
Because NIBCO
®
PEX pipe is flexible, installations are easier than rigid systems. It can be bent to make turns or navigated around
obstructions, thus lowering the number of fittings required in the installation. The minimum bend radius for NIBCO
®
PEX pipe is eight
times the outside diameter of the pipe. NIBCO bend supports can be used to hold a turn in place. Hangers that do not pierce or damage
the pipe wall may also be used to support the system.

Always Properly Support NIBCO

PEX Pipe
Our cross-linked NIBCO
®
PEX pipe is tough and durable. Yet, in most applications, it must be properly supported to protect against ex-
cessive strain. Please observe the following guidelines. Codes require the use of approved fastening devices. Make sure that supports
designed for use with plastic pipe are used whether one is mounting to either wood or steel. Metal supports designed for use with
plastic pipe may be used. Never use supports that have sharp edges.
For tubing 1” and below, on horizontal runs, we recommend the pipe be supported every 32” between each support, leaving a little
slack (
1
/
8
” to
3
/
16
”) in the tube to allow for normal expansion / contraction.
For tubing of size 1
1
/
4
” and above, 48” is the maximum spacing of horizontal supports.
Regardless of tubing size, vertical runs must be supported at the mid story point.
Never pull the tubing tight during the installation.
