Connecting Tubing to the Manifold

Connect the tubing to the manifold using either the ProPEX connection method or

QS-style fittings. Refer to the Uponor Product Catalog for fitting information.

ProPEX Connections

Square-cut the Tubing

Slide ProPEX Ring onto Tubing

Expand the Tubing

1. Use a PEX Cutter (E6081125, E6081128

or E6081501) to square-cut the tubing

perpendicular to the tubing length.

Note: Do not use a saw or similar cutting

tool as shavings may clog the manifold valves.

2. Slide the ProPEX Ring over the end of the tubing

until it reaches the stop edge.

Note: Ensure the ring is dry and free of grease to

prevent it from sliding out of place.

3. Attach the proper size ProPEX Expander Head onto

the expander tool and expand the tubing with the

proper number of expansions (see Table 1).

4. After expanding the tubing and ring, immediately

remove the expander tool and slide the tubing over

the fitting until the tubing reaches the stop on the

fitting. Hold the tubing in place for two or three

seconds to ensure a proper seal.

QS-style Fittings

1. When connecting the tubing with a QS-style fitting,

make sure the tubing is pushed all the way into the

fitting and tighten the fitting with a wrench.

Note: Do not over-tighten or twist the tubing.

2. If you need to remove a QS-style fitting from the

tubing, use a screwdriver to open the clamp ring

and remove the insert.
