Genaral Solder Sleeve Wire Splices
Genaral Solder Sleeve Wire Splices
Application
Our Solder Sleeve Wire Splices feature an all-in-one design that integrates a pre-fluxed solder preform, heat-shrink insulation, and environmental sealing rings into a single, easy-to-install unit. This design eliminates the need for soldering irons, allowing for simultaneous soldering, insulating, and sealing with just a heat gun. The transparent sleeve permits immediate visual verification of the solder joint quality. By streamlining the workflow, this solution significantly reduces installation time and guarantees process consistency across automotive, rail transit, and high-precision industrial wiring harnesses.
Series Overview
• SST-SXR Series: Polyolefin outer sleeve, 125°C (257°F), the solder rings meet environmental protection requirements, standard sealing, low-temperature solder ring melts at 118°C—ideal for heat-sensitive electronics
• SST-R Series: Polyolefin outer sleeve, 125°C (257°F), the solder rings meet environmental protection requirements, standard sealing, solder ring melts at 138°C
• SST-S Series: Polyolefin outer sleeve, 125°C (257°F), standard sealing, 138°C solder melt
• SST-W Series: Polyolefin outer sleeve, with integrated shield wire, 125°C (257°F), standard sealing, 138°C solder melt
Features and Benefits
• Four series tailored to distinct temperature and sealing demands
• Clear sleeve for hassle-free placement and visual quality control
• Low- and standard-temperature solder options (118 °C / 138 °C) for sensitive or high-duty circuits
• Encapsulated Protection: Heat-shrink sealing provides robust insulation, mechanical reinforcement, and superior corrosion resistance in one step.
• Field-Proven Reliability: Trusted performance across automotive, rail transit, and high-precision industrial equipment worldwide.
Color
White, Red, Blue, Yellow, Green, Purple, Orange
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 "CS" 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.
