Seachoice Marine Heat Shrink Butt Connectors 22-18 AWG Red

Seachoice marine heat shrink butt connectors, also called heat shrink butt splices or waterproof wire splice connectors, join two wires end to end. They are made for boat wiring and other harsh, wet environments. Each connector is crimped, then heated to form a sealed, insulated splice.

Key Features:

• Marine-grade construction: Made for wiring exposed to moisture, salt and vibration.
• Tin-plated copper barrel: The seamless tube is 99.9% pure copper with tin plating for strong current flow and corrosion resistance.
• 3:1 shrink ratio tubing: The proprietary nylon/polyolefin tubing has an adhesive lining. It shrinks to a tight, sealed fit around the wire.
• Clear tubing: You can inspect the wire and crimp after installation.
• Faster shrink times and better abrasion resistance than standard insulated splices.
• Easy installation: Insert the wire, crimp the connector, then apply heat for a complete environmental seal.

These connectors suit boat, trailer, automotive, RV and other 12V wiring repairs and installations where a durable, waterproof connection matters.
