Heat Shrink Butt Connectors – Waterproof 250-Piece Set
See what customers say about shopping with FactoryFast.
Product Description
Join stripped wires quickly with these heat shrink butt connectors using a heat gun instead of separate crimping tools or a soldering iron. Choose from four colour-coded sizes for wire ranges between 0.25–0.34 mm² and 4–6 mm², then apply heat to shrink the sleeve and melt the internal solder around the join.
These waterproof wire connectors from Randy & Travis Machinery carry an IP67 rating and combine heat-shrinkable tubing, hot-melt adhesive, copper and a low-temperature solder sleeve. With 250 connectors packed in a storage box, you can keep several sizes on hand for home, vehicle and other general wiring projects while choosing the required size by colour.
Key Features
-
250-Piece Colour-Coded Connector Assortment
The set includes four connector sizes identified by white, red, blue and yellow colouring. This makes it easier to locate the appropriate size while working across different wiring projects. -
Heat-Activated Solder Seal Connection
Each sleeve contains a low-temperature solder section positioned around the wire join. Applying heat melts the solder while shrinking the surrounding tubing around the connection. -
IP67 Waterproof-Rated Sleeves
The connectors carry an IP67 waterproof rating once correctly installed. Hot-melt adhesive works with the heat-shrink tubing to seal around the joined wires. -
3:1 Heat Shrink Ratio
The heat-shrinkable tubing has a 3:1 shrinkage ratio. It contracts around the wire connection as evenly applied heat activates the sleeve. -
Four Wire Size Ranges Included
The assortment covers 0.25–0.34 mm², 0.5–1.0 mm², 1.5–2.5 mm² and 4–6 mm² wire sizes. Different quantities are supplied across each range to support a variety of common wiring tasks. -
Wide Operating Temperature Range
The specified operating range extends from -55 °C to 125 °C. This gives the connectors clearly defined temperature parameters for suitable installations. -
Storage Box Included
All 250 solder seal connectors are supplied in a dedicated storage box. The case helps keep the different colour-coded sizes separated and accessible between jobs.
