Making ⅜" ProPEX connections
When making a ⅜" ProPEX connection, expand the ring once
on each side to properly t over the piping. Refer to the following
instructions to make a ⅜" ProPEX connection.
1. Square cut the PEX piping perpendicular to the length of the
piping. Remove all excess material or burrs that might affect
the tting connection.
2. Expand each side of the ring once.
3. Slide the expanded ring over the end of the piping. Extend
the end of the ring over the end of the piping no more than
1
⁄16" (1mm).
4. After the ring is on the piping, continue with the regular steps
for making a proper connection with your specic tool.
Proper expander tool and head maintenance
• Use a lint-free cloth to apply a light coat of lubricant to the cone
prior to making any ProPEX connections.
• If used regularly, apply the lubricant daily to the cone of the
ProPEX expander tool. Failure to keep the tool lubricated may
result in improper connections.
Caution: Excessive lubrication may result in improper
connections. Only use a small amount of lubrication to
keep the tool working properly.
• Keep all other parts of the tool free from lubricant.
• Once a month, soak the heads in degreasing agent to remove
any grease from between the segments. Clean the cone using
a clean, dry cloth.
Important tips for a proper ⅜" ProPEX connection
• The thicker ⅜" ProPEX Ring shrinks over the tting faster
than larger-sized rings.
• When the temperature is below 40°F (4.4°C), fewer
expansions are required.
