Application
The SST-H series is engineered for applications requiring enhanced mechanical strength. It features a one-piece design integrating a flux-coated solder ring within a colored double-wall heat shrink sleeve. Upon heating, the solder bonds the wires while the dual-wall tubing shrinks to provide a waterproof seal. Distinguished by its superior tensile strength and abrasion resistance, the SST-H series also features color-coding for instant wire gauge identification, simplifying installation and ensuring connection reliability.
Features and Benefits
• 3:1 Shrink Ratio: Accommodates a wide range of wire gauges.
• High Tensile Strength: Double-wall structure provides robust mechanical protection and pull-out resistance.
• Waterproof Sealing: Hot-melt adhesive lining blocks moisture and corrosion.
• Color-Coded: Full-sleeve coloring indicates wire size for fast, error-free selection.
Color
Clear, Red, Blue, Yellow
Notes:
• Custom sizes and colors are available upon request. Technical specifications are subject to change without prior notice. Minimum order quantities (MOQ) may differ from standard packaging quantities.
• If your application calls for a product that combines both crimping and a solder-ring, choose our "STBT" Series.
• For complete material specifications, please contact us to request the data sheet.
• When different wire gauges are required on the two ends of the splice, opt for the "CA" Series.
