F. Increase of the O.D. of the Wire with Layers of Tape
This paragraph gives the procedure to increase the outer diameter of the wire insulation to make a seal
in the crimp barrel of the splice if the outer diameter is less than the minimum diameter specified in
Table 1 or Table 2.
(1) Make a selection of a solvent from Table 7.
(2) Make a selection of a TFE tape from Table 7.
(3) With a clean wiper and solvent, clean the wire insulation a minimum of 2.5 inches from the end of
the wire.
(4) Dry the clean area with clean wiper.
(5) Wind the necessary number of layers of tape on the wire insulation to make the O.D. of the wire
between the minimum and the maximum O.D. of the wire.
Make sure that the layers of tape make a 100 percent overlap.
