The Aluminum Compression Splice 4-Orange to 6-Blue is a rugged, dual-rated connector engineered to splice one copper or aluminum 4 AWG conductor and one 6 AWG conductor in demanding electrical environments. Designed for service entrance and utility applications, it features a high-conductivity aluminum body, pre-filled oxide inhibitor, and a durable nylon insulator that withstands crimping forces while offering long-term protection. With ANSI C119.4 Class A-3 compliance and color-coded orange and blue ends, this splice ensures secure, code-compliant connections in overhead and underground settings.
