• Adhesive Lining with Heat Shrink: Heat shrink tubing with adhesive lining provides a water-tight seal, protects against moisture, and adds an extra layer of strain relief for long-lasting, durable connections.
• Easy Installation: Simply strip the wires, insert into the connector, and crimp for a solid connection.
• Wide Compatibility: Works with various wire sizes and applications for secure electrical connections.
• Pure Copper with Tin Plating: Offers excellent conductivity and corrosion resistance for long-term use.
• Brazed Barrel: Ensuring uniform crimping and resistance to vibration.
• Clear Crimp Points: Designed for straightforward wire placement and crimping.

• Marine Applications: Heat shrink crimp terminals are a must-have in marine electrical systems, where moisture, saltwater, and environmental exposure lead to corrosion and electrical failure. The adhesive-lined heat shrink tubing forms a waterproof seal that prevents rust, providing long-term, reliable connections for boat wiring and other marine electronics.
• Underground Wiring: Ideal for underground electrical installations such as outdoor lighting and irrigation systems, heat shrink terminals offer exceptional moisture resistance. The heat-activated adhesive creates an airtight seal, protecting connections from water, dirt, and other contaminants, ensuring a durable solution for underground cables and outdoor electrical wiring.
• Well Pump Wiring: For well pump systems, heat shrink terminals ensure watertight and pressure-resistant connections. The adhesive lining seals out water, providing long-lasting protection from corrosion and ensuring the reliability of well wiring for years, even in fluctuating pressure environments.
• Chemical-Exposed Environments: In settings where electrical connections come into contact with chemicals, oils, or other corrosive substances, heat shrink crimp terminals provide superior chemical resistance. The durable tubing acts as a protective barrier, safeguarding connections in chemical processing plants, oil refineries, and other harsh industrial environments.
• Outdoor Installations: For outdoor electrical installations like solar panels, generators, or any system exposed to weather extremes, heat shrink crimp terminals offer a weather-resistant, UV-protected solution. They shield connections from rain, sunlight, and temperature fluctuations, ensuring long-lasting durability for outdoor use.

Heat shrink crimp terminals are engineered to provide secure, long-lasting electrical connections with superior protection. These terminals feature adhesive-lined heat shrink tubing, made from 3M Type MW adhesive-lined, translucent, semi-rigid polyolefin, which creates a waterproof, airtight seal when heated. This high-performance material ensures maximum durability and reliability in various harsh environments, including marine, industrial, and underground applications.

Key Material Benefits of Heat Shrink Crimp Terminals

• High-Quality Polyolefin Tubing: The semi-rigid polyolefin material used in heat shrink terminals offers excellent heat-shrink properties. It forms a tight, protective seal around the wire connection, providing long-lasting durability and resistance to moisture, chemicals, and mechanical stress. The translucent tubing allows for easy inspection of crimp points, ensuring a secure electrical bond.
• Adhesive-Lined for Waterproofing: The adhesive lining inside the heat shrink tubing activates when heated, creating a watertight barrier. This feature makes these terminals ideal for use in marine electrical systems, underground wiring, and environments exposed to water, oil, or chemicals. The adhesive also strengthens the connection, reducing the risk of corrosion and environmental damage.
• Versatility in Harsh Environments: Heat shrink crimp terminals are widely used in marine, automotive, and industrial applications, where protection from the elements is critical. The combination of polyolefin tubing and adhesive lining provides excellent resistance to mechanical stress, making them perfect for high-vibration environments and high-stress electrical systems.
• High Temperature and Cold Resistance: These terminals offer superior performance across a wide range of temperatures. The heat shrink polyolefin material is designed to withstand extreme heat, while also offering protection in cold environments where insulation is critical. The tubing helps to dissipate heat and prevent overheating, ensuring the longevity of electrical connections.
• Environmental Protection: Unlike non-insulated terminals, heat shrink crimp terminals provide comprehensive environmental resistance, shielding connections from moisture, chemicals, UV exposure, and mechanical wear. This makes them ideal for outdoor use, well pump wiring, and other applications where connections need to be protected from harsh conditions.
• Cost-Effective Durability: While heat shrink terminals may have a higher upfront cost than non-insulated options, their enhanced protection and durability minimize maintenance and replacement costs over time. The combination of adhesive lining and polyolefin tubing ensures that each crimped connection remains secure, even in challenging conditions, leading to a long-lasting, cost-effective solution.
