Introduction to SpliSeal
What is SpliSeal?
SpliSeal is a revolutionary wiring seal kit, originally developed and manufactured in the United States, and now available in Australia through our team at 313 Marine. These kits tackle corrosion and electrical failure using a cutting-edge potting polymer that ensures waterproof and weatherproof sealing. Whether you're a marine technician, trailer enthusiast, or vehicle electrician, SpliSeal delivers a professional-grade connection in under 60 seconds.
Why Sealing Wiring Matters for Australians
Australia’s diverse and often harsh weather conditions—from saltwater exposure on the coast to extreme dust in the outback—demand superior sealing solutions. Unsealed wiring can result in system failures, short circuits, or costly repairs. SpliSeal provides a rugged, waterproof seal that stands up to these environmental challenges, making it an essential tool for boat owners, trailer operators, and auto electricians across the country.

How to Use a SpliSeal Kit Step-by-Step
Setup and Safety
Always begin by wearing protective gear and ensuring a clean, dry workspace. Prepare your wire by stripping it clean, then choose the correct mould size and set up your glue gun.
Moulding and Sealing Process
Place the connector in the mould, insert the wire, and inject heated sealant using the glue gun. The mould ensures a tight fit while the sealant encases the wire for optimal protection.
Tips for a Flawless Finish
Use wire cleaner to remove debris before sealing. Ensure even heat distribution with the glue gun, and allow time for the sealant to fully cure before handling the wiring.
