Heat activated, color-coded nylon insulation shrinks around wire to seal out moisture and provide extra pull-out strength to the connection. Tin plated copper construction provides maximum conductivity and corrosion resistance. Funnel entry of insulation jacket makes wire insertion fast and easy. Hot-melt adhesive inner liner seals the connection against moisture, water, salt, and other corrosive compounds. Seamless inner barrel ensures consistent contact regardless of the location of crimp. Simple Installation Steps: 1. Select the correct splice size for the wire gauge. Strip the wires 0.3” (7.5mm) from the end and insert into the crimp. 2. Making sure the wire end is properly seated, make the crimp connection using a tool designed for insulation splices. 3. Apply heat directly to the splice, working from the center out to the edges, using a hot air gun or other heat source, until the tubing recovers and the adhesive flows. Allow to cool before inspecting splice and checking integrity.
