ABSTRACT:
A method and arrangement are provided to generate an environmental seal around a connection such as an electrical junction. The arrangement comprises a pad arrangement having a substrate and a sealant pad associated therewith. The sealant pad comprises a highly viscous sealant which, under pressure, can be forced into areas between adjacent wires, to provide effective moisture seals. According to preferred methods of the present invention a substrate having sealant thereon is folded around a junction to be sealed, such that the substrate retains the sealant against the electrical junction. In a step of the preferred method, pressure is applied to the enclosed sealant pad, generating hydraulic forces contained in such a manner as to the direct sealant between adjacent wires, spreading same apart. In preferred applications, preferred direction of sealant is facilitated by a preferred pressure die arrangement.
