Important Tips for a Proper ProPEX Connection
• If the fitting does not slide into the tubing all the way to the stop,
immediately remove it from the tubing and expand the tubing one
final time.
Note:
To avoid over-expanding the tubing, do not hold the tubing in
the expanded position.
•
Table 4
lists the recommended number of expansions for the various
sizes of PEX tubing. Experience, technique and weather conditions
influence the actual number of expansions. Fewer expansions may be
necessary under certain conditions. The correct number of expansions
is the amount necessary for the tubing and the shoulder of the fitting
to fit snugly together.
• A good connection is when the ProPEX Ring rests snugly against
the stop of the ProPEX fitting shoulder. If there is more than

Disconnecting a ProPEX Brass Fitting
ProPEX brass fittings are manufactured connections and can be concealed in
walls, ceilings and floors. However, when necessary, ProPEX Brass Fittings can
be disconnected. To disconnect a brass fitting:
1. Make sure the system is not pressurized.
2. Use a heat gun to heat one side of the ProPEX Ring. When the ring
