About This

Built For Heat Shrink Waterproof Connections: Purpose-built for heat shrink butt connectors & heat shrink terminals. The full section formed by the oval crimping can effectively prevent the wire from falling off. Compared with concave pit pressure, it can better prevent corrosion and oxidation, doesn’t cut through the insulation on your connectors to keep them water tight.
Full-Cycle Ratchet = Consistent & Repeatable Crimps: Full-cycle ratcheting mechanism ensures every crimp is completed to spec before release, reducing loose joints, pull-outs and rework—especially helpful for beginners and field repairs. The ratchet design also secures the wire connector while inserting the wire into the crimp.
Covers The Most-Used Wire Sizes (22–10 AWG): Three color-marked crimp cavities for common heat shrink terminal ranges (red/blue/yellow). Works across 22–10 AWG (0.5–6.0 mm²) for automotive, RV and boat electrical projects.
High-Quality Crimp Plier: The clamp head is heat treated with medium carbon steel, higher strength ensures durability. And the jaws are treated with black oxidation, which can ensure long-term corrosion resistance.
Portable And Save Effort: 9-inch long handle design wire crimper, when crimping large square terminals, save effort. Ratcheting leverage design reduces hand strain during repetitive crimping, making it a dependable tool for wiring harness builds, maintenance and DIY upgrades.
Versatile Wire Crimper: This insulated terminal crimper suitable for various DuraSeal splices, pvc, nylon pre-insulated terminals and butt splices.
