One-Step Solder & Seal – Our solder seal wire connectors melt solder and shrink tubing in a single heat step, creating a secure, waterproof, corrosion-resistant joint. Faster, cleaner and more reliable than twist caps or tape. Seamless Shop Fit – Compact stripper + color-coded, gauge-marked connectors keep your cart tidy and your workflow efficient—perfect for small benches, mobile service vans, and on-site repairs. Upgrade Your Results – Prep perfectly with the automatic wire stripper, then finish with heat-shrink solder connectors for “like-solder” strength and a clear, sealed finish that stands up to vibration and moisture. Made for Every Skill Level – Beginners love the self-adjusting action and color cues; pros appreciate repeatable results, time savings, and consistent pull strength. Quality & Assurance – RoHS/CE compliant connectors, ISO-managed production, free shipping, 30-day risk-free trial, and a 2-year warranty. Key Features Self-adjusting automatic wire stripper covers AWG 22–10; integrated cutter & crimper Heat-treated alloy blades for sharp, long-lasting performance Heat-shrink solder connectors with adhesive lining for waterproof, corrosion-resistant seals Thick copper barrels for high conductivity; color-coded with AWG marks for fast selection Ideal for automotive, marine, trailer wiring, household/electronics, and DIY harness building Quiet, smooth action suited to home or mobile service without disturbing others How to Use Strip – Set the wire in the jaws; squeeze once for a clean, accurate strip. Join – Overlap the conductors and insert into the correct butt connector size. Heat & Seal – Apply a heat gun until solder flows and the tube shrinks; adhesive beads form a clear waterproof seal. Verify – Light tug test for mechanical security and continuity. Use for repairs, upgrades, and new installs 3–4 times a week (or as needed), and pair with tidy routing and proper strain relief for best results. Why This Set? Because reliable wiring needs both perfect prep and a sealed connection. This bundle pairs a precision wire stripping tool with solder-and-seal connectors so you get faster installs, higher conductivity, fewer callbacks—and a cleaner, professional finish that justifies a premium project price.
