What’s Inside the Complete Kit
-
220PCS solder seal wire connectors (10–26 AWG): low-melt butt connectors with solder that flow and seal in seconds.
-
220PCS 3:1 adhesive-lined heat shrink tubing: black/red, 45 mm, six essential sizes for snug strain relief.
-
Dual-temperature 350 W heat gun: 482°F / 752°F (250°C / 400°C) heat gun for heat shrink tubing—even heating for flawless results.
Why It Works Better (and Faster)
Our solder seal wire connector design combines a tin solder ring with inner adhesive. Heat once and the wire connectors solder themselves while the tubing seals—no separate solder sticks needed. The result is a soldered connector that’s waterproof, corrosion-resistant and vibration-proof—ideal for marine, automotive, trailers, motorcycles, and DIY.
Highlights
-
One-step soldering connectors + sealing
-
Durable heat shrink solder bond that resists pull-out
-
Clean, low-resistance soldered wire connectors every time
Dual-Temp Heat Gun = Perfect Shrinks
Whether you call it a heat gun for shrink wrap tubing, shrink tube heat gun, or hot air gun for heat shrink tubing, the included 350 W tool delivers quick, even heat. Use the 482°F setting for small gauges; switch to 752°F for heavier wires and fast heat shrink soldering on larger joints.
High-Quality 3:1 Heat Shrink Tubing
Our adhesive-lined sleeves out-perform tape and generic tubing. The 3:1 recovery grips tight, wicks adhesive around the joint and adds strain relief—great with wire soldering connectors or alongside your existing solderless electrical connectors where extra insulation is needed.

Built for Real-World Jobs
From bilge pumps to brake lights, this kit covers it. Techs and hobbyists use it as a compact wire connector solder station for clean field repairs—no bench iron required. Pair with your favorite crimper when you need solderless connectors; use our solder on connectors when you need a permanent, sealed join.
How to Use (30-Second Workflow)
-
Insert stripped wires into the butt connector with solder.
-
Heat center ring until solder flows; continue until the clear tube fully shrinks.
-
Let cool; tug-test. You now have a sealed heat shrink electrical connector.
