CUSTOMER DRAWING
Thermofit Assembly Procedure
1. Strip the wires and install crimp type connector or solder wires together. Connector should be installed so that
1/6 ± 1/32 of conductor is exposed between the connector and the wire insulation, as shown in Figure 1.
2. Choose the proper size cap from the chart below. Place splice into cap so that the connector bottoms on the
rounded end of the cap.
3. Heat the assembly, using a Thermogun, Model 500A, or equivalent, equipped with a TG-12 or TG-13A
reflector.
4. The average length of time required for proper heating is given in the chart. However, since the heat sink effect
of various wire bundles may vary considerably, several trial specimens should be crossed-sectioned as shown in
Figure 2 before proceeding with production installations. If the area between the wires is not completely filled,
a longer heating cycle should be established.
5. With wire bundles of more than three wires, it is helpful to slightly deform the cap by pinching in the area
above the connection at the end of the heating cycle and then returning the cap to the heat for an additional
period to allow the cap to return to its cylindrical shape.
