22-16 AWG Non-Insulated Butt Splice Connectors - 100PCS

22-16 AWG Non-Insulated Butt Splice Connectors

Key Features

• Seamless barrel design ensures the connector will not split or open when crimped under high mechanical pressure.
• Manufactured from pure, high-grade electrolytic copper to deliver maximum electrical conductivity and minimal voltage drop.
• Electro-tin plated finish provides outstanding resistance against corrosion, oxidation, and rust in harsh marine and outdoor environments.
• Features an integrated wire stop in the center of the barrel to guide correct and equal wire insertion depth from both sides.

Replaces / Cross-Reference Part Numbers

• Standard 22-16 AWG Uninsulated Butt Joint
• Non-Insulated Parallel Connector 22-16AWG
• Marine Grade Bare Copper Splice Terminal

Compatibility & Fitment

• Universally compatible with standard 22, 20, 18, and 16 gauge (AWG) solid or stranded copper electrical wires.
• Suitable for low-voltage and high-amperage applications within marine, automotive, motorcycle, RV, commercial, and residential wiring harnesses.
• Designed for use with standalone heat-shrink tubing or electrical tape insulation layers to complete waterproof seals after connection.

When to Replace

• Existing wire splices are heavily corroded, green with oxidation, or causing excessive electrical resistance.
• The original crimp connection has pulled loose, resulting in intermittent electrical signals or complete circuit failure.
• Previous insulation surrounding the joint has degraded, melted, or cracked from high heat exposure.
• Splicing, extending, or repairing broken or severed conductors within an existing electrical harness configuration.

Installation Tips

• Ensure the main power source is completely isolated and disconnected before working on any electrical circuit.
• Strip approximately 1/4 inch of insulation off the ends of both copper wires, taking care not to cut or score the internal strands.
• Insert the first wire into the connector barrel until it rests against the center stop, then use a dedicated non-insulated crimping tool to compress the terminal firmly.
• Insert the second wire into the opposite end of the barrel, repeat the crimping process, and apply a moderate pull test to verify a secure mechanical hold.
• Slide a segment of adhesive-lined heat shrink tubing centered over the bare copper connector and apply heat uniformly until the tubing shrinks and seals the joint tightly against moisture.
