is clear, use a utility knife to carefully cut through the ring. Care
should be taken to cut only the ring and not the tubing. This will
protect the fitting from becoming gouged by the knife. Remove the
ProPEX Ring from the tubing with pliers or another tool to avoid
touching the hot ring.
Note:
Do not gouge the fitting when cutting the ProPEX Ring.
Nicks and gouges in the fitting may result in leaks. If nicked,
discard the fitting.
3. When the ProPEX Ring is removed, apply heat directly around the
fitting and tubing connection. Gently work the tubing back and forth
while pulling slightly away from the fitting until the tubing separates
from the fitting.
4. When the tubing is removed from the fitting, square cut the tubing
2" (minimum) from the end of the tubing.
5. Use a new ProPEX Ring and follow the steps to make a new ProPEX
connection. Allow the fitting to cool before attempting to make
another connection.
ProPEX Connection Troubleshooting Guide
Trouble-free ProPEX installations begin with a ProPEX 200 Battery Expander
Tool that is maintained in proper working condition. If the tool or segment
fingers are damaged, it is very difficult to make a proper connection. The
following troubleshooting guide is designed to assist with problems in the field.
Fittings Do Not Seal
For fittings that do not seal, follow the steps below.
1. Ensure the expander head is securely hand-tightened onto the tool.
2. Make sure the segment fingers are not bent. If the head does not
completely close when the electro-hydraulic drive unit is fully
retracted, replace the head.
3. Remove any excess grease on the segment fingers.
4. Examine the fitting for damage. Nicks and gouges on the fitting will
cause the fitting to leak.
5. Ensure the internal driver is not damaged or bent.
6. Make sure the last expansion is not held in the expanded position for
more than three seconds before the fitting is inserted. The longer the
tubing and ring are held in the expanded position, the greater chance
for a leak.
7. Be sure to rotate the tool

turn after each expansion.
Expansion is Difficult
If it is difficult to make an expansion, check to ensure the internal cone is
properly greased with Uponor-recommended Molykote G-n plus.
