Compliant with all electrical standards, Perfect for marine and automobile applications, whether you are working on your boat, Vehicle, Home or scientific project ## Why choose this product **Reliable Connections for Demanding Environments** — Haisstronica heat shrink butt connectors are engineered for durability and performance. The tinned copper core ensures excellent conductivity, while the thick barrel and high-quality heat shrink tubing with hot melt adhesive create a robust, waterproof seal. This prevents wire slippage and protects against corrosion, making them ideal for marine, automotive, and outdoor applications where moisture and vibration are common. Unlike basic connectors, these meet stringent ROHS, ISO, SGS, and CE standards, offering peace of mind for critical wiring jobs. **Ideal for DIY & Professional Installs, Not for Mains** — This kit is perfect for DIY enthusiasts, car audio installers, boat owners, and anyone needing to make secure, waterproof wire splices in low-voltage systems. The color-coding and clear gauge markings (22-10 AWG) make them user-friendly. However, these connectors are rated for 12V DC and are not suitable for high-voltage AC mains wiring. For mains electrical work, always consult a qualified electrician. If you need connectors for high-amperage or mains voltage, look for specialized industrial-grade products. ## How to use 1. Strip approximately 1/4 inch (6mm) of insulation from the ends of the wires you need to connect. Ensure the stripped ends are clean and free of damage. — Prepare Wires 2. Insert one stripped wire end into each side of the butt connector. Use a proper crimping tool to firmly crimp the barrel onto both wires, ensuring a secure mechanical connection. — Insert and Crimp 3. Using a heat gun (not a direct flame), apply heat evenly to the tubing over the crimped area. Heat until the tubing shrinks tightly around the wires and the internal adhesive flows out, creating a seal. — Apply Heat ## Product details | Field | Value | |---|---| | Core Material | Tinned Copper | | Insulation Material | Nylon | | Tubing Material | Polyolefin | | Sealant | Hot Melt Adhesive | | Application | Marine, Automotive, Home Wiring, Stereo Installation, Scientific Projects | | Usage Instructions | Strip wire ends, insert into connector, crimp firmly with a suitable tool, and heat tubing with a heat gun until adhesive flows and seal forms. | | Cost per use | 330 connectors total — ₹11.61 per connector | | Shelf life after opening | 24 months (typical for electrical components) | | Contraindications | Not for AC mains voltage wiring; not for use with wire gauges outside specified ranges. | | Allergens / common irritants | None commonly reported for this product type. | | Brand | haisstronica | | Model Number | HX1045 | | Color | Red, Blue, Yellow, White | | Material | Tinned Copper Core, Nylon Insulation, Polyolefin Tubing | | Quantity | 330 Pieces | | Wire Gauge Compatibility | 26-24 AWG (48 pcs), 22-16 AWG (150 pcs), 16-14 AWG (100 pcs), 12-10 AWG (32 pcs) | | Maximum Voltage | 12V DC | | Temperature Rating | 257°F (125°C) | | Shrinkage Ratio | 3:1 | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### How to choose the right wire gauge for these butt connectors? Each connector is color-coded and marked with its compatible wire gauge range (AWG). Red typically fits 22-18 AWG, Blue fits 16-14 AWG, Yellow fits 12-10 AWG, and White fits 26-24 AWG. Match your wire's gauge to the connector's specification for a secure crimp. ### Are these heat shrink butt connectors waterproof? Yes, these connectors feature a 3:1 heat shrink ratio with an inner lining of hot melt adhesive. When heated with a heat gun, the adhesive melts and seals the connection, providing a waterproof and corrosion-resistant joint suitable for marine and automotive use. ### What is the maximum voltage and temperature these connectors can handle? These haisstronica butt connectors are rated for a maximum of 12V DC and a temperature of 257°F (125°C). They are designed for low-voltage DC applications like automotive, marine, and home electronics, not for high-voltage AC mains wiring. ### Can I use these for mains electrical wiring in India? No, these connectors are specifically rated for low-voltage DC applications (up to 12V) and are not suitable for AC mains voltage wiring in India or elsewhere. For mains wiring, always use connectors designed for that purpose and consult a qualified electrician. ### How to buy original haisstronica heat shrink butt connectors in India?
