Terminals – Butt Splice (Waterproof)

Waterproof butt splice terminals are designed to create a strong, sealed, and corrosion‑resistant connection between two cables. They’re the go‑to choice for marine, trailer, and automotive environments where moisture, vibration, and salt exposure can quickly destroy standard connectors.

Key Features

• Fully waterproof design with adhesive‑lined heat‑shrink
• Tinned copper barrel for maximum corrosion resistance
• High‑strength crimp for secure cable joining
• Colour‑coded insulation for easy cable size identification
• Ideal for harsh environments including marine, off‑road, and trailer wiring
• Provides a long‑lasting, vibration‑proof seal

Why Choose Waterproof Butt Splices?

• Prevents water intrusion into the cable
• Protects against corrosion and electrolysis
• Ensures a reliable electrical connection even in wet or submerged areas
• Perfect for bilge pumps, trailer lights, battery systems, and general marine wiring

Common Applications

• Boat wiring repairs and upgrades
• Trailer rewiring (boat trailers, box trailers, caravans)
• Automotive and 4x4 electrical systems
• Joining cables in exposed or high‑moisture locations
• Any application where a standard butt splice won’t survive the environment
