Overview

The TE Connectivity 8-31818-1 is a precision-engineered insulated butt splice designed for reliable power and signal transmission in industrial environments. This splice accommodates wire sizes from 22 to 16 AWG (0.3 to 1.42 mm²) with a serrated barrel design and 0.061 in [1.55 mm] inside diameter, ensuring secure mechanical and electrical connections. The 509–3260 CMA wire size range supports applications requiring robust current-carrying capacity while maintaining signal integrity. Engineered for harsh conditions, the 8-31818-1 delivers consistent performance under temperature extremes from -40°C to +125°C, vibration, and mechanical stress. Its insulated construction provides dielectric strength and protection against environmental contaminants, making it suitable for machinery, control panels, and automation systems where reliability is critical. The splice’s design minimizes signal loss and contact resistance, ensuring long-term operational stability in high-duty-cycle applications. Ideal for field installations and maintenance, the 8-31818-1 simplifies wire splicing with a tool-compatible design that accommodates standard crimping tools. Its compact form factor allows for dense packing in junction boxes and terminal blocks, while the gold-plated contacts (where applicable) enhance corrosion resistance and conductivity. This splice is a proven solution for connecting stranded or solid conductors in industrial automation, renewable energy systems, and infrastructure projects where downtime must be minimized. Compatible with a broad range of industrial wiring standards, the 8-31818-1 integrates seamlessly into existing systems without requiring specialized tools or training. For applications demanding high durability and low maintenance, this splice reduces the risk of connection failures, improving system uptime and reducing lifecycle costs.
