Overview

TE Connectivity 8-34138-2 is a high-reliability parallel splice designed for parallel wire connections in industrial applications. This uninsulated, tin-plated copper splice accommodates wire sizes from 12 to 10 AWG (2.62 to 6.64 mm²), with a barrel inside diameter of 0.129 in (3.28 mm) and a closed barrel design for secure mechanical retention. The splice supports a maximum operating temperature of 170°C, making it suitable for high-temperature environments such as power distribution, control panels, and industrial machinery. The 8-34138-2 is part of TE Connectivity’s SOLISTRAND parallel splice family, optimized for robust electrical connections with low contact resistance. It is compatible with hand tools referenced in TE Connectivity’s catalog (tools 1, 2, 3, 7, 10, and 14) for consistent crimping performance. The splice is supplied as a loose piece in small packs, ensuring flexibility for low-volume or custom assembly requirements. Ideal for applications requiring parallel wire splicing in harsh or demanding conditions, this splice is commonly used in manufacturing, energy, and transportation sectors. Its copper construction and tin plating provide excellent conductivity and corrosion resistance, while the closed barrel design ensures long-term mechanical integrity. The splice meets voltage ratings appropriate for the connected wire gauge, ensuring reliable performance in critical systems. For parallel splices requiring insulation support or higher voltage ratings (up to 600V), consider TE Connectivity’s PLASTI-GRIP or COPALUM parallel splices. The 8-34138-2 is specifically optimized for uninsulated, high-temperature applications where durability and conductivity are paramount.
