Haisstronica 180PCS Solder Seal Wire Connectors

SKU CH-C1MB-WYTNE

A 180-piece assortment of heat-shrink solder-seal connectors that melt to form waterproof, insulated butt splices for automotive and marine wiring

  • Product colorBlack
  • Rock-solid joints from high-purity solder rings that flow and adhere fully when heated
  • Waterproof seal created by hot-melt adhesive that melts and wraps each connection
  • Clear inspection window via EVA heat-shrink tubing for visual confirmation of solder penetration
  • 180-piece assortment covering five colour-coded sizes for versatile wire gauges
  • Abrasion-resistant EVA tubing protects the joint for long-term reliability in harsh environments

180-piece solder seal connector kit

This kit supplies 180 heat-shrink butt splices with integrated solder rings and hot-melt adhesive lining. Each connector creates a watertight, mechanically strong joint when heated, eliminating the need for separate crimping and taping steps. The assortment covers five colour-coded sizes for quick identification on the job.

Capacity and headroom for wiring tasks

The 180-piece count supports multiple vehicle or marine rewiring projects before replenishment. Five size ranges accommodate common automotive wire gauges, while the adhesive-lined tubing seals against moisture and vibration. Very large gauge cables or high-current bus bars exceed the kit's terminal capacity and require larger lugs.

Upgrade from crimp-only or tape-sealed joints

Technicians moving from standard crimp connectors plus electrical tape gain a single-step, sealed connection that resists corrosion and pull-out. The transparent heat-shrink sleeve allows visual confirmation of solder flow, reducing rework. Buyers needing hundreds of terminals for production-line volume will find the 180-piece pack insufficient.

Questions about this item

Will these 180 solder-seal connectors work with the older crimping tool I already own?

They are heat-shrink solder seal connectors, so you apply heat rather than crimp; your existing crimping tool is not needed for the connection itself.

How can I verify the 180 connectors have sealed properly after heating?

The transparent EVA heat-shrink tube lets you see the solder melt and flow around the wires, and the hot-melt adhesive will appear as a continuous ring when the joint is fully sealed.

The pack lists 180 pieces — does it include a heat gun or only the connectors?

Only the 180 solder-seal wire connectors are supplied; a suitable heat source such as a heat gun or lighter must be purchased separately.
