Raychem's Solder Sleeve one-step, heat-shrinkable wire and cable interconnection devices are a labor saving alternative to conventional wire and cable termination methods such as craft-sensitive, time-consuming, hand soldering or crimping. The one-step terminators create strong, soldered connections. They consist of a heat-shrinkable sleeve and a premeasured, fluxed solder band. When heated, the tubing shrinks and the solder melts, making reliable, insulated terminations.
