Fully Sealed Robust Structure: Features an integrated fully sealed design that achieves zero cable exposure after crimping. The precision-engineered 3:1 heat shrink tubing, combined with an optimized adhesive formula, forms an IP67-rated waterproof seal when heated, completely blocking moisture ingress—far surpassing competing products' butt-seam designs (which are prone to cracking and lack waterproof certification).
Pure Copper Core: Constructed from tinned pure red copper, offering 40% higher conductivity and significantly superior oxidation and corrosion resistance compared to ordinary brass terminals. Ensures stable current transmission, extends the service life of electrical systems, and fundamentally reduces connection failure risks.
Smart-Compartment Toolbox: Innovative removable compartment design allows each terminal type to be stored separately. Retrieve individual connectors without carrying the entire toolbox, keeping the workspace organized. The high-quality sealed case remains orderly even when overturned and supports refills for repeated use.
Multi-Environment Certification: Certified for marine and automotive electrical standards, with flame-retardant and waterproof properties suitable for underground and damp environments. Compatible with AWG 16-14 wire gauges, ideally adapted for wiring in vehicles, vessels, household circuits, and scientific projects.
All-Scenario Connection Kit: Includes ring, fork, spade, butt, and other terminal types to cover common electrical engineering applications. The heat shrink tubing utilizes military-grade puncture-resistant material, providing abrasion and shock resistance for enhanced connection stability in harsh conditions such as vehicle vibrations and marine turbulence.
