Z-Bite Fitting Removal
1. Turn off the system water supply and relieve the pressure by
opening faucets or valves to allow as much water to drain from
the system as possible. The piping may still contain water that can
drain out when the fitting is removed. Be prepared to contain or
absorb the water to prevent damage to flooring or other surfaces
2. Place the appropriate sized Z-Bite removal clip on the tube with
the grooved side facing the fitting.
3. Slide the removal clip up to the end of the fitting.
4. With one hand, hold the fitting and press the removal clip against
the end of the fitting. This action spreads the teeth on the stainless
steel retaining ring.
5. With the other hand, pull the tube out of the fitting while keeping
the teeth of the retaining ring spread.
6. Before reuse of the fitting, check the following items:
a. If using PEX tube, be sure the liner is in the fitting. If not,
retrieve it from the end of the tube or replace it.
b. Inspect the tube end to be sure it was not damaged, gouged or
scratched as it was removed from the fitting. If necessary, trim
the tube end so that a smooth sealing surface is available.
Tube Liner Removal from a Z-Bite Fitting
Z-Bite fittings are supplied with the tube liner installed in the fitting.
Use of this liner is mandatory when using PEX tube in a Z-Bite fitting.
This liner may be removed if the fitting is being used with CPVC or
copper tubing.
1. Needle nose pliers are needed to remove the liner.
2. Using the pliers, gently wiggle the tube liner and pull it past the
o-ring seal.
3. Using the appropriate size removal clip, press the grooved side of
the clip against the release ring on the end of the fitting to expand
the teeth of the retaining ring.
4. While keeping the teeth expanded, pull the liner out of the fitting with
the pliers.
Slip Coupling Installation
A Slip Coupling is a special fitting used when it is not possible to
move the ends of the tube far enough apart to install a regular
coupling. The slip coupling can be installed by deflecting the tube
instead of moving the ends apart.
1. First, cut the ends of the tube to create a gap between the ends
of the tube measuring approximately ¼” larger than the distance
from the indicating ring on the body of the fitting to the short end
of the fitting. This gap should not be larger than 2”.
2. Chamfer and deburr the ends of both tubes and mark the insertion
depth on both tubes.
3. Deflect one of the tubes and slide the long end of the slip coupling
into place until it hits the tube stop.
4. Line the tubes up.
5. Place the appropriate sized Z-Bite removal clip on the tube with the
grooved side toward the long end of the fitting.
6. Press the removal clip against the long end of the fitting to spread
the teeth on the stainless steel retaining ring and slide the coupling
so the short end is installed on the other tube to the proper
insertion depth.
