The 8-34173-2 is a pre-insulated PIDG parallel splice designed for reliable wire joining in control circuits and power wiring applications. It accommodates wire sizes from 12 to 10 AWG (5,180–13,100 circular mils) with a maximum splice insulation length of 0.843 inches (21.41 mm) and supports wire insulation diameters up to 0.200 inches (5.08 mm). The splice features a copper body per ASTM B-152 with tin plating per ASTM B-545, vinyl insulation rated UL 94V-0, and is color-coded yellow for easy wire size identification. It is designed for use with AMP application tooling to ensure uniform, high-quality terminations and provides exceptional barrel contact and tensile strength through serration or dimple features inside the splice barrel. This splice is suitable for joining multiple wires where the combined cross-sectional area must remain within the specified circular mil rating, making it ideal for automotive, industrial control, and heavy-duty power distribution applications.
