Abstract: A system for sealing an electrical terminal which includes a device for sealing a plurality of electrical wires to a wire attachment portion of an electrical terminal. The device includes a shrinkable tubing which is placed over the plurality of electrical wires such that one end thereof extends over the wire attachment portion of the electrical terminal. A sealant/adhesive is placed within the heat shrink tubing and has a first portion proximate to the edge of heat shrink tubing. The sealant/adhesive has a strip of high viscosity sealant/adhesive proximate a strip of low viscosity sealant/adhesive. Upon the application of heat to the device after installation of the device over the electrical terminal, the shrinkable tubing starts to recover, the first portion of the sealant/adhesive flows and seals free ends of the plurality of electrical wires to seal the free ends of the electrical wires.

Abstract: A system and device for sealing a plurality of electrical wires to a wire attachment portion of an electrical terminal, wherein a shrinkable tubing is placed over the plurality of electrical wires such that one end thereof extends over the wire attachment portion of the electrical terminal. A band of the high viscosity sealant/adhesive is placed within the heat shrink tubing adjacent to the edge of heat shrink tubing. A band of the low viscosity sealant/adhesive is placed within the heat shrink tubing. Upon the application of heat to the device, the shrinkable tubing starts to recover, the high viscosity sealant/adhesive seals the edge of the shrinkable tubing and the low-viscosity sealant/adhesive flows across and through the plurality of electrical wires to create a seal. The high viscosity sealant/adhesive prevents flow of the low-viscosity sealant/adhesive from contaminating the electrical terminal.
