Proseal Wire Harness Butt Connector - Red - 18-20 AWG - Master Appliance

Part #: 10666

The Master Appliance 10666 Proseal Wire Harness Butt Connector provides professional technicians with a robust solution for creating secure, sealed electrical connections. Designed for 18-20 AWG wires, this red heat-shrink butt connector ensures a reliable mechanical crimp and a dependable environmental seal, crucial for maintaining electrical integrity in demanding automotive and industrial settings. It delivers consistent wire contact, minimizes voltage drop, and promotes superior current flow for lasting performance.

Key Features

  • Environmental Sealing: Features heat-activated, adhesive-lined tubing that melts and flows to create a waterproof, corrosion-resistant seal, protecting connections from moisture, dirt, and contaminants. The adhesive remains contained within the barrel for optimal electrical contact and a clean finish.
  • Secure Crimp Connection: Engineered for use with professional crimp tools, this seamless butt connector ensures strong mechanical retention and consistent electrical continuity by preventing the barrel from opening during crimping.
  • Broad Wire Compatibility: Suitable for 18-20 AWG wires commonly found in passenger cars, light trucks, heavy-duty vehicles, and agricultural and construction equipment, making it versatile for various automotive wiring and industrial applications.
  • Enhanced Durability: Robust insulation and heat-shrink tubing maintain their length after heating, providing superior wire support, strain relief, and connection integrity under vibration, temperature cycling, and exposure in harsh environments.
  • Visible Gauge Identification: The distinct red body allows for clear and quick identification of 18-20 AWG circuits, simplifying harness service and troubleshooting for professional mechanics.

Applications

Ideal for sealing and protecting wire splices in:

  • Automotive wiring harness repairs underhood, under-dash, and along frame rails.
  • Truck, bus, and fleet electrical systems, including lighting, sensors, and auxiliary equipment.
  • Off-road, agricultural, and construction equipment exposed to mud, washdowns, and vibration.
  • Marine wiring in bilges, consoles, and engine compartments where moisture resistance is critical.
  • Industrial machinery, control cabinets, and outdoor electrical installations requiring sealed butt connections.
