½" to 2" adapter installation
1. Assemble the joint by inserting the
pipe into the adapter until it meets
the pipe stop. Note that you can use
clean water to ease the assembly
process. Wetting the pipe and/or the
adapter will ease the pipe-insertion
process. Be sure to check the pipe
insertion depth using the reference
mark on the pipe’s outside diameter.
(See step 5 in the previous Prepress
section on
page 5
.)
Important!
Only press the adapter
when the pipe is fully inserted into
the adapter.
2. Using the correct size press jaws
in the press tool, place the jaws
over the bead on the adapter.
Ensure the press tool and jaws
remain perpendicular to the pipe’s
centerline.
3. Press the tool’s trigger or actuation
button to begin the press cycle.
The cycle is complete when the
jaw fully encloses the mouth
of the adapter. Once the cycle
is complete, release the jaws
from around the adapter. Refer
to the press tool manufacturer’s
instructions for further details.
4. After the connection is complete,
inspect the pressed joint to ensure
the pipe has remained fully inserted
during the pressing process.
5. Pressure test the system to ensure
a proper connection. If a leak is
found, re-press the connection.
Note:
Uponor ProPEX copper
press adapters are designed to
leak air or water when improperly
pressed to help installers identify
improperly pressed connections.
