Product Highlights

  • All-in-One Solder & Seal: Low-temperature solder ring melts to fuse wire conductors while outer sleeve shrinks for a watertight bond.
  • IP67 Waterproof Protection: Dual-walled polyolefin tubing with hot-melt internal adhesive rings seals against water and corrosion.
  • Transparent Visual Inspection: Clear tubing allows 360-degree inspection of soldered wire strands and insulation overlap.
  • Multi-Gauge Compatibility: Color-coded sizes (S21 Red 22-16 AWG, S31 Blue 16-12 AWG, S41 Yellow 12-10 AWG).

NEED TO KNOW

FREQUENTLY ASKED QUESTIONS

Quick answers to common questions about fitment, installation, delivery and product use.

How do I install solder sleeve connectors?
Strip wire ends ~8mm, slide them into the sleeve so the stripped strands overlap under the solder ring, and apply heat using a heat gun until the solder melts and the tubing shrinks.
Can I use a lighter instead of a heat gun?
A heat gun with a deflector nozzle is recommended to provide uniform 360-degree heat without scorching the polyolefin sleeve.
Are these suitable for marine and automotive engine bays?
Yes, their IP67 watertight seal resists moisture, engine oil, vibration, and salt corrosion.

Product Details

Description

Waterproof Heat Shrink Solder Sleeve Butt Connectors (IP67 Sealed)

Solder, insulate, and waterproof wire splices in a single step with Waterproof Heat Shrink Solder Sleeve Connectors. Featuring a low-temperature internal solder ring and dual hot-melt adhesive rings inside a polyolefin heat shrink tube, these connectors create an IP67 watertight electrical connection.

All-in-One Solder & Seal Technology

As heat is applied, the center solder ring melts to fuse the stripped wire strands together, while the outer sleeve shrinks and hot-melt glue rings seal the wire insulation, preventing moisture ingress and wire corrosion.

Key Features

  • All-in-One Solder & Seal: Melts solder around conductors while shrinking polyolefin tubing for a waterproof seal.
