Thomas Betts 2A-18 Butt Splice Terminal Crimp-on 100 Pack

Product Description

The THOMAS BETTS 2A-18 is a non-insulated, crimp-on butt splice terminal designed to join two wire ends in a single inline connection. Manufactured from copper with a TiN (titanium nitride) contact plating, it delivers reliable conductivity and resistance to oxidation in demanding wiring environments. The terminal measures 0.62 inches in overall length and 0.12 inches in overall diameter, making it compact for tight junction boxes and panel wiring. Rated to UL 94 V-2 flame standards and compliant with MIL-T-7928 and CSA requirements, the 2A-18 is a trusted choice for licensed electricians and industrial maintenance technicians working to established wiring codes.

This butt splice terminal is suited for residential, commercial, and light industrial wiring applications where a clean, low-profile inline splice is required. Its non-insulated design is appropriate when splices will be covered by separate insulating sleeves or heat-shrink tubing, or where the installation environment calls for a bare terminal per job spec. Electricians typically use this terminal in panel wiring, control panel builds, harness assembly, and field splicing of branch circuit or low-voltage control wiring. The 2A-18 accepts two wire entries, one at each end, for a direct butt-splice configuration.

Compatibility

Designed as an OEM-style crimp terminal for use in standard inline butt-splice applications across residential, commercial, and industrial electrical wiring assemblies.

Installation Notes

Installation should be performed by a licensed electrician or qualified technician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify absence of voltage before making any splice connection. Use a calibrated ratcheting crimp tool rated for the terminal size to ensure a secure, gas-tight crimp. If the installation environment requires insulation, apply an appropriately rated heat-shrink sleeve or insulating boot over the completed splice before restoring power.
