Applications
HSC-H is engineered for applications requiring maximum clarity and flexibility. It features an E/MAA ionomer sleeve with superior transparency and elasticity, lined with a high-bond hot-melt adhesive. The adhesive forms a strong bond with PVC/PE wire insulation and metals, creating a waterproof, corrosion-resistant seal. Its exceptional elasticity and puncture resistance ensure reliable strain relief even in harsh vibration environments. More durable and easier to inspect than conventional connectors, HSC-H lowers total installation costs.
Features and Benefits
• 3:1 Shrink Ratio: Accommodates a wide range of wire sizes with a tight seal.
• Crystal Clear Visibility: Industry-leading transparency allows for precise visual inspection of the crimp and wire insertion.
• High Elasticity & Toughness: Superior elongation prevents splitting during crimping and resists mechanical damage over time.
• Strong Adhesive Bond: Advanced hot-melt adhesive bonds aggressively to PVC, PE, and metals for a waterproof seal.
• Wide Temp Range: Operates reliably from -40°C to 105°C, ensuring flexibility even in cold environments.
Notes
• Match each wire gauge to the corresponding color-coded butt splices. For complete material specifications, please contact us to request the data sheet.
• Custom sizes and colors are available on request. Specifications may change without notice, and minimum order quantities (MOQ) can differ from standard pack counts.
