Dual Cavity 22–18 AWG Butt Connector Mold, Aluminum Wire Splice Mold for 22–18 AWG Butt Splices, Used with Solder Seal Sticks to Create Sealed Electrical Connections for Automotive & Marine

The SpliSeal Dual Cavity Butt Connector Mold is a reusable aluminum tool designed to help form sealed butt splice connections for 22–18 AWG electrical wiring. Built for precision and repeatable use, this mold supports the creation of consistent splice enclosures when used with compatible SpliSeal Sealant Sticks, sold separately. Machined from solid aluminum, the mold provides durability, heat resistance, and dimensional stability during repeated use. The dual-cavity design allows users to form enclosed 1-to-1 or 1-to-2 wire splice connections, supporting clean and uniform sealing for electrical repair and wiring projects. This mold is intended for use in automotive, marine, trailer, and general electrical applications where sealed splice connections are needed. When used correctly with appropriate SpliSeal sealing materials, it helps protect wire splices from moisture, vibration, and environmental conditions commonly encountered in these settings. Compact and easy to store, the SpliSeal Dual Cavity Mold fits conveniently in toolkits or workshops and is suitable for both professional technicians and experienced DIY users. This product is a forming tool only and does not include solder, sealant sticks, glue guns, or heating equipment.

• DUAL CAVITY 22–18 AWG BUTT CONNECTOR MOLD: This mold is designed specifically for forming sealed butt splice connections for 22–18 AWG wire sizes. The dual cavity layout supports creating consistent 1-to-1 or 1-to-2 wire splice seals when used with compatible solder or sealant sticks, ensuring a professional grade finish for smaller gauge wiring projects.
• PRECISION-MACHINED ALUMINUM CONSTRUCTION: Machined from solid aluminum, this butt connector mold offers durability, heat resistance, and dimensional accuracy. The rigid metal body supports repeated use while maintaining consistent cavity shape for reliable electrical splice sealing, making it a long lasting tool for automotive technicians and marine electronics experts.
• RELIABLE SEALING OF SPLICE CONNECTIONS: Designed for use with non-insulated connectors and SpliSeal sealant sticks, this mold facilitates the creation of sealed splice connections. Sealant sticks, connectors, and heating tools are sold separately.
• AUTOMOTIVE, MARINE & ELECTRICAL APPLICATIONS: Suitable for electrical wiring projects in automotive, marine, trailer, and general electrical repair environments. Supports creating sealed splice connections for 22–18 AWG wiring exposed to vibration, moisture or outdoor conditions when properly sealed with the recommended potting polymer and heating equipment.
• COMPACT, REUSABLE TOOL FOR WIRE SPLICING: The compact round mold design allows for easy storage and transport in tool kits or professional workshops. Built for reuse, it supports repeated splice forming without deformation when used according to recommended procedures, providing a cost effective alternative to traditional one-time use heat shrink tubing methods.
