Reliable Solder-Seal Connections for Everyday Wiring
Built for Cleaner, More Reliable Wire Repairs
Five practical features for everyday electrical projects.
💧 Waterproof & Reliable Connection
Moisture, corrosion, and vibration can weaken exposed wire repairs. These heat shrink solder butt connectors form a sealed joint for more dependable connections.
🎨 Color-Coded Size Variety
Stop sorting through mismatched parts. Four color-coded AWG ranges make it easier to select the right connector for each splice.
🛠️ Wide Application Use
One organized kit supports wire repairs, extensions, and connections across a range of vehicle, marine, RV, and home electrical projects.
🔥 High-Quality Polyethylene Material
Durable polyethylene heat shrink tubing surrounds a precision solder ring that melts when heated to form a strong mechanical and electrical bond.
🧰 Organized & Portable Storage
Keep commonly used connectors and tubing together in one labeled storage box, so the parts you need are easier to find during a project.

Small box with compartments for different wire sizes. I already tried one, and it melts evenly; the connections are almost perfectly bonded. The risk is when applying heat with a lighter (even though it doesn't require much time), so you have to be careful. Excellent product. It's only suitable for small wires. Perfect for automotive electricians. I'll buy it again because I prefer those few seconds with the lighter to the risk of a bad wire splice. I recommend it.

Love this product because it holds up to the standard that most suppliers cant even match, also does good job with little things when it’s important.
