Crimp Tool Use
The crimp tools supplied with the NIBCO
®
PEX system are high quality instruments designed for heavy-duty use. However, normal use
will require that these tools be adjusted on occasion. Before beginning a job, the installer should conduct a “test” crimp to ensure
that the tool is working properly. If several consecutive joints fail the go /no-go gauge, then the tool may be out of adjustment. During
normal wear conditions, the crimp tool’s crimp diameter tends to increase. NIBCO tools come with instructions for maintaining the tool
and keeping it in proper adjustment. Please follow these instructions.
NIBCO’s 5-Step Method for a Great Crimp Connection
Because NIBCO
®
PEX pipe is extruded to tight tolerances you don’t have to worry about crimp rings sliding or insert fittings falling out
as the system is being “roughed in.” The installer can quickly “hand fit” the system, then go back and crimp each fitting to make the
connection permanent. After crimping, our connections form a reliable and permanent seal. After all connections have been crimped,
the system can be immediately pressure tested. NIBCO crimped connections are immediately permanent whether the installation tem-
perature is hot or cold.
We urge you to thoroughly read the instructions for our 5-step method before beginning any installation.
Step 1
Cut the pipe to length squarely. A rough, jagged or irregular cut may result in a failed connection.
