Chapter 7
Making a ProPEX connection
Uponor ProPEX ASTM F1960 (CAN/CSA B137.5)
cold-expansion fittings make solid, permanent,
manufactured connections without the need
for torches, glues, solder, flux, or gauges. The
unique shape memory of Uponor PEX
piping forms a tight seal around the
fitting, creating a strong, reliable
connection. This chapter shows how
to make proper ProPEX connections using
one of the following tools.
• Milwaukee M12, M12 FUEL, or M18 ProPEX expansion tools
• Milwaukee M18 FORCE LOGIC ProPEX Expansion Tool
• ProPEX 201 Corded Expander Tool
• ProPEX Hand Expander Tool
Distance between fittings
Uponor requires a minimum
distance between ProPEX fittings
to avoid damaging the fittings
during installation and to protect
against elevated stress on the
pipe and fittings. Refer to Table 7-1
for the minimum distance between
fittings, which is expressed as cut
length of pipe.
General ProPEX connection tips
• If the fitting does not slide into the piping all the way to the
stop, immediately remove it from the piping and expand the
piping one final time.
