SCOPE

This document outlines the procedure to be followed to obtain immersion resistant multiple wire butt splices using

Thermofit Multi-Wire In-Line Splice Sealing System D-436-42/-43.

2.0 PROCEDURE

a)

Pass the wires to be attached to one barrel through the separate three wire seal. (Item 3) Pass the wires

to be attached to the other barrel through the sealing sleeve from the three hole insert end.

b)

Strip wires 5/16” to 11/32” and crimp into splicer using one of the approved crimping tools (see

below). Care must be taken that the wires remain untwisted between the splice and the three wire seals or the

sealing sleeve cannot be positioned properly.

c)

Position the separate seal as close as possible to the splicer. Hold this piece in position by squeezing

the wires directly behind it, and slide the sealing sleeve over the assembly so that the separate seal is as far

inside the sleeve as possible.

d)

Apply heat, using the recommended heat source, first to the “separate” seal end, and then the other.

Heat should be applied until insert melts and flows axially along the wires.
