Butt Splice Wire Connector BN22 4AWG

Overview

The BN22 4AWG Non-Insulated Butt Splice Wire Connector provides a seamless, highly reliable inline splice for heavy-duty electrical wiring applications. Manufactured from high-grade electrolytic copper with protective tin plating, this crimp connector guarantees maximum conductivity, low voltage drop, and exceptional resistance to corrosion.

Key Features and Specifications

Designed specifically for 4 AWG (approximately 22 mm²) solid or stranded conductors, the BN22 features a seamless tubular barrel that resists splitting under heavy crimping pressure. An integrated internal wire stop ensures accurate insertion depth from both ends, enabling symmetric, high-pullout-force crimp joints suited for demanding high-current circuits.

Applications and Installation

This heavy-duty connector is widely used in automotive power systems, battery wiring, marine electrical panels, and industrial control equipment. For optimal results, strip the conductor insulation to length, insert into the barrel, and compress using a standard ratchet crimping tool designed for uninsulated terminals. Slide a heat shrink tube over the finished connection for environmental protection and insulation.
