Making
3
⁄8" ProPEX
Connections
The
3
⁄8" ProPEX Ring must be expanded
once on each side to properly fit over the
tubing. Refer to the following instructions
to make a
3
⁄8" ProPEX connection.
1. Square cut the PEX tubing
perpendicular to the length of the
tubing. Remove all excess material
or burrs that might affect the fitting
connection.
2. Expand each side of the
3
⁄8" ProPEX
Ring once.
3. Slide the expanded ring over the end of
the tubing. Extend the end of the ring
over the end of the tubing no more
than
1
⁄16" (1mm).
4. After the ring is on the tubing,
continue with the regular steps for
making a proper connection with your
specific tool.
Disconnecting a ProPEX
Brass Fitting
ProPEX brass and EP fittings are
manufactured connections that can be
concealed in walls, ceilings and floors.
When necessary, ProPEX brass fittings can
be disconnected.
Important! EP fittings cannot be
reclaimed.
Refer to the following guidelines for
disconnecting a ProPEX brass fitting.
1. Ensure the system is not pressurized.
2. Use a utility knife to carefully cut
through the ProPEX Ring.
Important! Do not heat the ring prior
to cutting it. Take care to cut only
the ring and not the tubing or fitting.
Gouges in the fitting may result in
leaks. If you accidentally damage the
fitting, you must discard it.
3. Remove the ProPEX Ring from the
tubing.
4. After removing the ring, 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.

Important Tips for a
Proper
3
⁄8" ProPEX
Connection
• The thicker
3
⁄8" ProPEX Ring
shrinks over the fitting faster
than larger-sized rings.
• When the temperature is
below 40°F (4.4°C), fewer
expansions are required.
