SKU CH-NZSC-S202S

Kit of 160 heat-shrink solder-seal butt connectors covering AWG 22-18 with low-melting solder rings (118-138 °C), built-in solder paste and waterproof adhesive lining

  • Product colorBlack
  • Waterproof seal with extended adhesive rings for better moisture resistance
  • Solder paste and brush included to improve connectivity and reduce cold joints
  • Flexible solder ring compresses for secure single-handed installation
  • Low-melting-point solder (118–138 °C) cuts heating time and protects tubing
  • Lead-free components certified to ROHS, ISO 9001:2008, SGS and CE standards

Kit Contents and Use

The Intashi kit supplies 160 heat-shrink solder-seal connectors sized for AWG 22-18 wire. Each sleeve contains a low-melting-point solder ring with adhesive lining and a central separation barrier that aligns the two conductors. The pack also includes solder paste and a brush for pre-tinning strands. It suits automotive, marine and general electrical repairs where a sealed, insulated joint is required.

Thermal Behaviour

The solder ring melts between 118 and 138 degrees Celsius, so a standard heat gun shrinks the tubing and flows the solder in a short heating cycle. This lower temperature reduces the risk of damaging the outer insulation during installation. The connectors are passive components; they draw no power and generate no noise in service.

Accessory Impact

The supplied solder paste and brush let the installer coat strands before insertion, which cuts the chance of cold joints and improves electrical continuity. The transparent tubing allows visual confirmation that the solder has flowed fully and that no conductor is exposed, helping to prevent arc faults. The separation barrier ensures equal insertion depth from both ends without measuring.

Questions about this item

How do I install the heat-shrink solder sleeves and what step often causes a bad joint?

Strip wires to equal length using the built-in separation barrier, insert both ends, apply the supplied solder paste with the brush, then heat evenly until the low-melting-point ring flows at 118-138 °C and the adhesive rings seal; skipping the paste or uneven heating creates cold joints.

What maintenance or replacement will the connectors need later?

The sleeves are single-use, lead-free solder rings that form a permanent, waterproof seal once heated; no periodic maintenance is required, but any damaged connection must be cut out and replaced with a new sleeve from the 160-piece kit.

What limit appears first during sustained high-current use?

The low-melting-point solder ring reflows between 118 and 138 °C, so continuous current that raises the joint above this range will melt the connection before the heat-shrink tubing degrades.
