Thomas Betts 2B-14 Butt Splice Terminal Crimp-on 100 Pack

Product Description

The THOMAS BETTS 2B-14 is a non-insulated, crimp-on butt splice terminal designed to create secure, low-resistance inline wire connections. Constructed from copper with a tin nitride (TiN) contact plating, the 2B-14 accepts two wire entries and measures 0.62 inches in overall length with a 0.12-inch overall diameter. It meets CSA, UL, MIL-T-7928, and RoHS requirements, making it suitable for demanding electrical and control wiring applications. Electricians and control panel wiring technicians reach for this style of terminal when building wire harnesses, splicing conductors in junction boxes, or extending runs in low-voltage control circuits.

The 2B-14 is suited for residential, commercial, and light industrial electrical work where an inline wire splice is required. Its non-insulated design is common in panel wiring, engine harness work, and equipment control circuits where the technician applies a separate heat-shrink sleeve or insulating boot after crimping. This SKU ships in a 100-piece package, making it practical for service vans, panel shops, and electrical contractors who regularly perform splice work.

Key Features

• Crimp-on connection style for fast, tool-based termination without soldering
• Copper contact material with TiN plating for corrosion resistance and reliable conductivity
• Non-insulated barrel — compatible with separate heat-shrink or insulating sleeves
• Two-wire entry design for true inline butt splicing
• Meets MIL-T-7928, CSA, UL Listed (File E9809), UL 94 V-2, and RoHS requirements
• 100-piece package quantity supports high-volume wiring work

Compatibility

Designed as an OEM-style crimp butt splice terminal for use in general electrical wiring, control panel assembly, and wire harness fabrication where a non-insulated inline splice connector is specified.

Installation Notes

Installation requires a ratcheting or bench-mount crimp tool rated for non-insulated barrel terminals — do not substitute pliers, as an improper crimp will compromise pull-out strength and electrical continuity. De-energize all circuits before splicing conductors and verify with a meter before handling bare wire ends. Work performed in permanent building wiring must comply with the applicable edition of the NEC. Because the barrel is non-insulated, a listed insulating sleeve or heat-shrink tubing should be applied over the finished crimp before returning the circuit to service.
