RB wire splicing connectors are available dry or grease filled. They provide 100% electrical crimp splices equivalent to soldered connections on various sizes of solid wire having plastic, pulp, and single-wrapped paper insulation. RB series connectors are used to quickly splice various sizes of insulated, solid copper conductor wires.
Simply insert a stripped or unstripped wire end (see tables on back for sizes) into the connector and crimp the brass connector shell with a RB crimping tool (Catalog No.190). The tin-plated phosphor bronze insert contains sharp internal tangs to penetrate wire insulation and create a positive electrical connection.
