Dual Cavity Butt Connector Mould 22-18AWG | Auto & Marine

Dual Cavity Butt Connector Mould – 22-18AWG | Weatherproof Electrical Sealing for Auto, Marine & More

Create perfectly sealed, weatherproof wire connections every time with this Dual Cavity Butt Connector Mould. Designed for 22-18AWG (22-18ga) wires, this aluminum alloy mold is ideal for automotive wiring, boat electrical systems, home electrical repairs, and any application where a reliable, corrosion-resistant splice is essential. Say goodbye to exposed connections — this mold makes professional-grade sealed joints fast, easy, and repeatable.

Key Features

• Dual Cavity Design: Mold two butt connector joints simultaneously for faster work on multi-wire projects.
• Compatible with 22-18AWG Wire: Perfect for small-gauge electrical wiring used in automotive, marine, and general electrical applications.
• Durable Aluminum Alloy Construction: Built to last and easy to clean — resists heat and wear from repeated use.
• Weatherproof & Anti-Corrosive Results: Sealant injected through the mold creates a watertight, corrosion-resistant connection that holds up in harsh environments.
• Easy to Use: Simple 4-step process — strip, crimp, mold, and seal. No special expertise required.
• Versatile Application: Great for automotive wiring harnesses, boat/marine electrical, trailer wiring, RV repairs, and general DIY electrical work.

How to Use

1. Strip wire ends: Strip the insulation from wire ends and insert into the butt connector.
2. Crimp the connector: Use a crimping tool to firmly secure the wire inside the butt connector.
3. Prepare and place in mold: Lightly brush the mold cavities with oil (engine oil or cooking oil both work) to prevent sticking. Insert the crimped wire splice into the mold and close it securely.
4. Inject sealant: Inject flame-retardant sealant through the mold's filling port. Wait approximately 30 seconds, then open the mold — your sealed connection is complete!

Note: Always brush oil (engine oil or cooking oil) on the mold before each use to prevent the sealant from sticking. Use flame-retardant glue/sealant for best results.

Frequently Asked Questions

Q: What wire gauge is this butt connector mould compatible with?

A: This dual cavity butt connector mould is designed specifically for 22-18AWG (22-18ga) wire. It is ideal for small-gauge automotive, marine, and general electrical wiring projects.

Q: What type of sealant should I use with this butt connector mold?

A: It is recommended to use a flame-retardant sealant or glue for the best and safest results. Always brush oil (engine oil or cooking oil) on the mold cavities before use to prevent the sealant from bonding to the mold and making removal difficult.

Q: Can this mould be used for boat and marine electrical work?

A: Yes! This butt connector mould is specifically designed for use in automotive, marine/boat, and general electrical applications. The sealed connections it creates are weatherproof and anti-corrosive, making them ideal for the moisture-heavy environments common in marine wiring.

Q: Is the mould reusable?

A: Absolutely. The durable aluminum alloy construction means this mould can be used repeatedly. Just remember to apply a light coat of oil before each use to keep the mold in good condition and ensure easy release after the sealant cures.
