Plumbing Installation Guide
Installation Instructions for Z-Bite Fittings
1. Using a tube cutter, cut the end of the tubing square. For PEX and
CPVC, blade type cutters are preferred as they do not flange or
burr the cut ends.
A wheel type of cutter works well for copper tube.
2. Examine the end of the tube for any scratches, gouges or lines that
might prevent the o-ring from sealing on the surface of the tube.
3. Using the deburring tool, chamfer the outer edge of the cut tube
end and mark the insertion depth on the tube.
4. Examine the fitting to be sure that the tube liner is present.
This liner is required when using PEX tube. If using copper or
CPVC tube, the liner may be removed. See Tube Liner Removal
instructions.
5. Using a slight twisting motion, insert the tube into the Z-Bite fitting
until it bottoms out in the fitting socket. Some resistance can
be expected as the end of the tube moves past the teeth on the
retaining ring and o-ring seal. The mark for insertion depth should
be visible approximately 1/8"from the end of the fitting.
6. Ensure tube is properly installed by pulling on pipe to check for
restraint.
7. Once all fittings have been installed, pressurize the system and
check for leaks.
8. Please refer to the Zurn PEX Plumbing Installation Guide for
additional information on the installation of PEX plumbing systems.
