Complete set of 250/100 heat shrink solder seal wire connectors Why you need this kit Makes reliable, longlasting splices faster and easier than loose soldering or crimponly methods. The builtin solder ring forms a solid electrical joint while the heatshrink sleeve seals and insulates the connection. Prevents moisture intrusion and corrosion with a heatactivated, weatherresistant seal — ideal where durability matters. Designed for professionallevel repairs across automotive, marine, and household applications where dependable connections are essential. Key benefits and features Combined solder and shrink action: builtin solder ring melts when heated to create a secure electrical bond; the outer sleeve simultaneously shrinks to lock and insulate the splice. Waterproof and corrosionresistant: heatactivated shrink tubing produces a tight, weatherproof seal around the joint for outdoor or damp environments. Professional quality performance: engineered for reliable connection strength in automotive, marine, and household electrical repairs. Function and compatibility: suitable for electrical connections and wire splicing needs across typical wiring systems; compatible with standard heat sources such as a heat gun or propane torch. Kit size: supplied as a complete set of 250/100 heat shrink solder seal wire connectors for multiple repairs and projects. Typical applications Automotive: or extend wiring for stereos, lighting, sensors, and harnesses where vibration and exposure require durable splices. Marine: reconnect bilge pump leads, navigation lights, and other boat wiring that must resist moisture and corrosion. Household: fix appliance leads, lighting circuits, or patch extension cords and household wiring safely with insulated, sealed joints. How it solves common problems Eliminates weak or exposed splices by creating both a mechanical and electrical connection in one step. Reduces failure from moisture, salt, or corrosion with a shrinktoseal outer sleeve. Saves time on repeated soldering and taping by combining soldering and insulation into a single heated application. Basic use instructions Strip wire ends, insert into the connector so conductors meet in the solder ring, and apply heat evenly until the solder ring melts and the sleeve contracts. Allow to cool to form a sealed, insulated connection. Reliable, professional results for automotive, marine, and household wiring repairs without unnecessary complexity.
