• Secure Connection for 12-10 AWG Wire: Color-coded yellow for easy identification, these terminals ensure a solid and reliable crimp for larger 12 to 10 gauge wires. • Waterproof Environmental Seal: Featuring adhesive-lined polyolefin tubing, a simple application of heat shrinks the tubing and melts the adhesive, creating a durable, waterproof, and corrosion-resistant barrier. • Crystal Clear for Inspection: The transparent heat shrink tubing allows for visual confirmation that the wire is properly crimped and positioned before the final seal, guaranteeing a perfect connection. • Fully Insulated for Safety: The connector provides full insulation over the male tab connection point, preventing electrical shorts and protecting the connection from dirt, moisture, and contaminants.
