| 1- Cutting
|
|
|
| FlowGuardTM tubing can be easily cut with a
wheel-type plastic tube cutter, a hack saw or other fine toothed hand or power
saws. Use of ratchet cutters is permitted, provided blades are sharpened
regularly. A miter box should be used to ensure a square cut when using a saw.
Cutting tube as squarely as possible provides optimal bonding area within the
joint. If any indication of damage or cracking is cracking is evident at the
tube end, cut off at least 5 cm beyond any visible crack. |

| 2- Deburring /
Beveling. |
|
|
| Burrs and fillings can prevent proper contact
between tube and fitting during assembly, and should be from the outside and
inside of the tubing. A chamfering tool is preferred but a pocketknife or file
are suitable for this purpose. A slight bevel on the end of the tubing will
ease entry of the tubing into the fitting socket and minimize the chances of
pushing solvent cement to the bottom of the joint. |

|
|
|
3- Fitting
Preparation.
Wipe any dirt or moisture from the fitting sockets and tubing end. Check the
dry fit of the tubing and fitting. The tubing should make contact with the
socket wall 1/3 to 2/3 of the way into the fitting socket. At this stage,
tubing should not bottom out in the socket. |

|
4 & 5. Primer /
Cleaner Application
Primer or cleaner prepares the bonding area for the addition of cement and
subsequent assembly. It is important to use a proper applicator. A dauber or
natural bristle paint brush approximately 1/2 the size of the tubing diameter
is appropriate. Apply primer to both the outside of the tubing end and in the
fitting socket. Do not allow primer to puddle in the fitting |
|
 |
|
|
|
| 6 & 7. Solvent
Cement ApplicationUse only CPVC cement or joint failure may result.
When the primed pipe and fitting surfaces are dry, apply a heavy, even coat of
cement on the tubing end. Apply a thin coat inside the fitting socket. |
|
 |
|
|
|
| 8. Assembly
|
|
|
| Immediately insert the tubing into the fitting
socket, rotating the tubing 1/4 to 1/2 turn while inserting. This motion
ensures an even distribution of cement within the joint. Properly align the
fitting. Hold the assembly for approximately 10 seconds, allowing the joint to
set-up. An even bead of cement should be evident around the joint. If this bead
is not continuous around the socket edge, it may indicate that insufficient
cement was applied. In this case remake the joint to avoid potential leaks.
Wipe excess cement from the tubing and fittings surfaces for an attractive,
professional appearance. |
