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 the device further includes a first piece of heat shrink tubing having a predetermined length, wherein the first piece of heat shrink tubing has been placed over the plurality of electrical wires such that one end thereof extends over the wire attachment portion of the electrical terminal; a second piece of heat shrink tubing having a predetermined length, wherein the second piece of heat shrink tubing has a smaller diameter than the first piece of heat shrink tubing, and wherein the second piece of heat shrink tubing is placed partially inside the end of the first piece of heat shrink tubing that extends over the wire attachment portion of the electrical terminal; and a band of adhesive placed within the first piece of heat shrink tubing adjacent to the second piece of heat shrink tubing.

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.
