100-piece AWG 22-18 connector kit

This kit supplies one hundred solder-seal wire connectors sized for AWG 22 to 18 conductors. Each piece combines a solder ring with dual adhesive-lined heat-shrink tubing so a single heat-gun pass completes a sealed joint. The product is aimed at automotive, marine and general electrical repair where a fast, insulated splice is required.

Transparent heat-shrink with IATF 16949:2016 listing

The clear tubing lets you verify solder flow and wire position before the joint cools, supporting visual inspection without magnification. Two hot-melt adhesive rings per connector bond to the insulation, creating a moisture and abrasion barrier suited to harsh environments. The exclusive sleeve material resists premature shrinkage so the solder melts before the tubing contracts.

No crimp tools or separate solder needed

Because the solder is pre-loaded inside the sleeve, you only need a heat gun — no crimper, flux or hand-soldering iron. This reduces the tool count for field repairs and speeds up work in tight spaces where conventional crimp barrels are hard to position. The connectors are produced under ISO 9001:2008, RoHS, SGS and CE compliance programmes.

Questions about this item

What wire gauges does the AWG 22-18 connector accept?

The connector is rated for AWG 22 to 18 wires, covering the range printed on the pack.

What physical space is needed to fit the heat-shrink sleeve?

The sleeve shrinks to a tight seal around the joint, so only enough room for the unshrunk tube and a heat gun nozzle is required.

How do you install these without crimping, and what step do people miss?

Strip the wires, insert them into the sleeve, apply heat until the solder ring melts and the adhesive rings flow, then let it cool undisturbed — skipping the cool-down often leaves a weak joint.
