Install Instructions

Cut the spun-closed end off of the stub
out, then deburr and clean the outside
of the tube with sand cloth.
YOU’LL NEED
Copper cutting /deburring tool
Sand Cloth
After properly running and fastening the PEX tube, it’s time to ter-
minate the run into a nished area of the house (through a oor
or a wall). Although there are some situations where it makes
sense to crimp the tube directly to a valve or xture (basement
laundry or sink), it is best use a copper stub out due to their rigid-
ity and resistance to bangs and bumps that could cause leaks.
Fastening PEX Tube
Support the Fitting
To prevent stress on the crimp joints,
always support the tube before and after
the tting.
Minimum Bend Radius
Do not bend tube too tightly. The minimum
recommend bend radius is six times the
tube size (i.e. ½″ tube = 3″ bend radius).
When making a 90° turn, use bend
supports.
Tube Through Studs
Grommets should be used when running
tube through studs to prevent tube damage
and reduce noise transfer. Tube that is run
within 2″ of a stud nailing surface must be
protected with a metal stud guard.
No Metal Hangers
Metal hangers can damage PEX tube,
we recommend only plastic hangers be
installed. To prevent noise transfer, only
use hangers that keep the tube off of the
nailing surface (studs and joists).
RECOMMENDED HANGERS:
Tube Talon, Sioux Strap or Suspensulator.
Tube Between Joists and Stud Bays
To make it easier to run tube in stud or
joist cavities, use the Power Bar, it installs
quickly and is totally adjustable (USBs
located in the pipe hanger offering).
Leave Room for Thermal Movement
PEX needs room to expand and contract.
Allow tube to dip between hangers and
never over-tighten. Many Sioux Chief hang-
ers are designed to let the tube contract
and expand without the possibility of
over–tightening.
Hanger Spacing
Hangers should be used every 32″
on horizontal runs and every 4′ on
vertical runs.
Finishing Tubing Runs
Crimp PEX tube to a straight PEX stub
out or a stub out elbow depending on
whether you need to make a turn as
you come through the wall. Make sure
stub out is properly secured (see page
6 for tips on fastening PEX tube).
YOU’LL NEED
Crimp tool
Crimp rings
Plastic Hangers
Using two wrenches, compress the
stop valve onto the copper tube. Be
careful not to over-tighten the joint.
