Overview
TONFUL Electric HSWN closed-end solder sleeve connectors combine a transparent heat-shrink sleeve with a copper spring, solder ring and colored end closure. Compare four catalog models by combined copper cross section, sleeve dimensions and end-closure color. The transparent sleeve encloses a copper spring, solder ring, sealing insert and colored glass end closure.
Features
- Closed-end design: the tinted glass ball forms the end closure.
- Internal connection components: a square copper-wire spring and fluxed solder ring are enclosed by the sleeve.
- Sealing inserts: glue rings are part of the original connector construction.
- Color identification: choose the model using its glass end-closure color and copper-section range.
- Visual inspection: the transparent sleeve allows the internal assembly to be viewed.

Selection Guide
Compare the combined copper cross section with the exact HSWN model. Confirm the conductor combination, heating instructions and installation conditions before assembly. Send the mating-part reference or assembly drawing for selection assistance.
Applications
Enclosed wire-end connections and compatible multi-wire assemblies in equipment harnesses, maintenance work and OEM wiring projects. Confirm wet-location suitability, conductor combinations and the required protection level for the exact model and finished assembly.
Ordering Information
Provide the full HSWN model reference, combined copper cross section and conductor arrangement, order quantity and intended application. Include packaging, labeling and delivery requirements for OEM and wholesale enquiries.
