Final Stage of Installation
During the final stage of installation,
install the finishing items in the structure.
Set and connect all lavs, tubs and water
closets. This section discusses the
supporting components used at this stage.
Straight and Angle
Stop Valves
Point of use at the fixture is the
intended use of ProPEX straight and
angle stop valves. These valves allow
for direct transition from PEX tubing to
the riser. To review ProPEX connections,
refer to Section 3. Uponor features the
following types:
• EP Straight and Angle Stop Valves
• Chrome Plated Brass ProPEX Straight
and Angle Stop Valves
• Chrome Plated Brass Compression
Straight and Angle Stop Valves
EP Valves
EP Straight and Angle Stop Valves are
constructed of durable engineered plastic
and precision-cut ceramics. They resist
chemical and mineral build-up, along
with corrosion, pitting and scaling and
they enable PEX-to-PEX and point-of-
use shutoff at the fixture.
Chrome Plated Brass
Compression Stop Valves
(Straight and Angle)
Because Uponor AquaPEX tubing has the
same outside diameter as standard copper
pipe, you can use standard compression
straight and angle stop valves with Uponor
AquaPEX tubing. An insert stiffener is
required. The insert is included with the
stop valves from Uponor. You can also
purchase inserts separately when needed.
Directions for Use
1. Square-cut the tubing perpendicular to
the tubing length.
2. Place the nut and then the compression
ring over the end of the tubing.
3. Use the brass compression ring
included with the stop valve.
4. Install the brass or stainless steel insert
into the tubing end. Be sure to set the
insert completely against the end of
the tubing.
5. Slowly tighten the compression nut to
the opposing thread.
Note: Re-tighten all compression
fittings after initial installation.
6. Wait 30 minutes to allow the tubing to
relax, and then re-tighten each fitting.
