3M 5731C Cold Shrinkable Inline Splice Kit

3M 5731C Cold Shrinkable Inline Splice Kit is a three-conductor inline splice for 8–4 AWG power conductors, designed to join sections of TECK-90 armored or non-armored cable in underground or exposed installations. It uses a Cold Shrink PST Jacket Tube made from EPDM rubber and accommodates cable insulation outer diameters from 0.95 to 1.40 inches, enabling a single inline splice for three conductors. The kit is rated for up to 600 V, making it suitable for low-voltage splicing in industrial environments. Kit contents include one cold shrink PST jacket tube; a compression connector is required but not included, and the assembly typically requires at least one roll of 3M Sheath Wrap for proper insulation and sealing. This inline splice solution is specifically intended for 3/C or 4/C armor power cables (TECK-90) and combines cold-shrink reliability with a pre-formed jacket assembly used in 3M’s Cold Shrink systems.
