Soldering Sleeve .125.
Termination sleeves consist of a heat-shrinkable, transparent, polyvinylidene fluoride sleeve with an inner, pre-fluxed, solder preform and two thermoplastic sealing inserts. When heat is applied, the solder melts and flows to provide a superior connection between the ground lead and the shield. At the same time, the two thermoplastic sealing inserts melt and the outer sleeve shrinks to provide an environmentally protected termination. Otherwise, they are essentially the same.
Very convenient. Strip the wire ends, insert in the sleeve, and apply the heat gun.
A little expensive but they do make a very secure connection and are easy to use.
