Set of 160 thickened copper ring terminals plus 80 double-wall self-adhesive heat-shrink tubes designed for reliable, long-lasting electrical connections. Why this kit matters Maximum conductivity: Thickened copper eyelets deliver low-resistance connections for efficient power transfer and reduced heat buildup. High-temperature durability: Reinforced copper construction resists deformation and corrosion under elevated temperatures for dependable performance in demanding environments. Protected, sealed connections: Included double-wall, self-adhesive heat-shrink tubes provide strong insulation and moisture protection, extending the life of each joint. Faster, safer installation: Closed pad design streamlines crimping and mounting; the built-in inspection window lets you verify correct wire insertion before crimping. Key features Material: Thickened copper ring terminals for improved conductivity and mechanical strength. Insulation: 80 double-wall self-adhesive heat-shrink tubes included for moisture sealing and electrical insulation. Compatibility: 160 ring terminals sized for wire gauges from 2 to 10/12 Gauge (covers a wide range of common wiring needs). Installation aids: Closed pad layout for simplified crimping and an inspection window to confirm proper conductor placement. Practical applications Automotive: Ideal for battery, starter, alternator and ground connections where low resistance and high-temperature resistance matter. Marine and RV: Heat-shrink seals and corrosion-resistant copper help protect connections exposed to moisture and vibration. Electrical panels and equipment: Use in fuse boxes, control panels and industrial machinery for reliable, serviceable terminations. What you get 160 copper ring terminals in assorted sizes compatible with 2 to 10/12 Gauge wire 80 double-wall, self-adhesive heat-shrink tubes for each crimped connection Notes for best results Strip wire to the correct length and use the inspection window to confirm insertion before crimping. Apply heat evenly to the shrink tube to activate the adhesive liner and ensure a proper seal. This kit provides the conductivity, heat resistance and protective sealing needed for secure electrical connections across automotive, marine and general electrical applications.
