IMPORTANT!
This procedure is only for nozzle and sprue heater leads when standard lead lengths are not long
enough.
This procedure is not to be used for extending thermocouple wire leads. Splicing thermocouple
wires will cause false and/or erratic temperature readings.
When required, standard thermocouples are available with longer wire lead lengths.
To install the kit, do the following:
1. Strip the ends of the wire and the wire supplied with the kit until 6 mm (0.2 in) of wire lead is
exposed on both.
2. Slide heat shrink tubing over the butt connector. Make sure the butt connector is centered in
the tubing.

3. Insert the wires into both ends of the butt connector until no wire lead is visible.

4. Using a crimping tool, crimp one end of the butt connector at a time.
5. Shrink the tubing using a heat gun.
6. Seal the ends of the heat shrink tubing where the tubing meets the wire lead insulation.
