FDD1.25-187 Insulated Quick Disconnect Bullet Female Connector

FDD1.25-187 Insulated Quick Disconnect Bullet Female Connector is an essential wiring component that allows for rapid, reliable, and insulated connection and disconnection of electrical circuits. This specific female bullet terminal is engineered for use with 22-16 AWG conductors, providing a secure crimp and pairing seamlessly with corresponding male bullet terminals. The pre-insulated nylon housing not only ensures electrical safety by preventing accidental contact but furthermore color-codes the connection for easy size identification, which streamlines assembly and maintenance processes. Technicians rely on the FDD1.25-187 to establish durable connections in automotive, marine, and industrial environments where space is limited and serviceability is critical. Therefore, choosing this terminal guarantees fast wire termination and excellent strain relief for long-lasting performance.

Key Features:

• Quick Disconnect Functionality: Allows for fast, tool-free connection and separation of circuits, significantly speeding up repair or component replacement.
• Insulated Housing: The nylon insulation provides reliable dielectric strength and protects against short circuits, enhancing user and system safety.
• Color-Coded for AWG: Features red insulation, designating the connector for 22 AWG to 16 AWG (0.5 mm² to 1.5 mm²) wire sizes, ensuring correct application.
• High Conductivity Metal: Constructed from tin-plated copper or brass, this component guarantees low resistance and optimal current flow.
• Crimp-On Termination: Easily installs onto the conductor using standard ratcheting crimp tools, creating a secure, permanent mechanical and electrical bond.
