THERMOFIT ASSEMBLY PROCEDURE
1.0 SCOPE
This document outlines the procedure to be followed to obtain immersion resistant 3 or 2 to 1 in-line splices using
Thermofit In-Line Splice Sealing System D-436-52/-53.
2.0 PROCEDURE:
a) Strip all wires 7.92 (0.312) to 8.74 (0.344).
b) Attach the single lead to the appropriate size crimp splice using a Raychem AD-1377 Crimp Tool.
c) Pass the wires to be attached to other barrel through the sealing sleeve from the three-hole insert end.
d) Insert wires into barrel and crimp. Care must be taken that the wires remain untwisted between the crimp
splice and the three wire seal or the sealing sleeve cannot be positioned properly.
e) Apply heat, using the recommended heat source, first to the three-hole insert and then the other. Heat should
be applied until insert melts and flows axially along the wires.
