Prepress
Select the correct size pipe and Uponor
ProPEX copper press adapter. Ensure
both are clean, in good condition and
free from damage and imperfections.
Carefully remove tape, labels or foreign
matter. Ensure the pipe or fitting is
round, clean and free of burrs and
surface imperfections.
Pipe preparation
1. Square cut the pipe. Use a rotary
pipe cutter whenever possible.
2. Deburr internal and external pipe
ends using a fine-tooth file.
Note:
You may use commercially
available deburring tools to ensure
a smooth interior and exterior at
the pipe end.
3. Clean the pipe end of debris to
avoid damage to the O-ring upon
pipe insertion.
4. Inspect the Uponor ProPEX copper
press adapter to ensure the
O-ring is undamaged and seated
correctly within the O-ring groove.
The O-ring should be free of cuts,
gouges or missing material at the
surface. If the O-ring is damaged
or missing, do not use the adapter.
If the O-ring is undamaged but is
partially out of the groove, gently
move the O-ring back into the
groove. If the O-ring does not
seat in the groove, do not use
the adapter.
5. Insert the pipe fully into the adapter
until it meets the stop. With the
adapter in place, mark the pipe’s
outside diameter at the edge of
the adapter. You can also use a
tape measure. Ensure the insertion
depth is clearly marked to attain
the proper insertion depth. Refer
to
Table 2

depth dimensions.
