Wire Splice Jig 10 Gauge – Hands-Free Hot Glue & Silicone Waterproofing System

Waterproofing wire connections shouldn’t be messy or frustrating.

The Wire Splice Jig 10 Gauge – Hands-Free Hot Glue & Silicone Waterproofing System securely holds wires in perfect alignment while you seal inline connections using hot glue or silicone. This eliminates shifting and twisting while adhesives cure, helping you achieve clean, durable, and professional-looking waterproof joints.

For best results, the jig should be used with a light lubricant or mold release applied to the contact surfaces before use. This prevents adhesive from bonding to the jig and allows for easy removal once the glue or silicone has cured.

Each component in the kit supports the full workflow — from initial wire alignment to final encapsulation — keeping the splice centered and stable throughout the process. The result is consistent coverage, improved durability, and a cleaner finish every time.

Compact and workshop-ready, this kit is ideal for automotive wiring, marine applications, outdoor electronics, trailers, lighting, and general repairs. Whether you’re a professional installer or a hands-on DIYer, this system makes waterproof wire splicing faster, cleaner, and more reliable.

Tip: Soldering the connection before sealing and using a light mold release will help ensure the strongest, cleanest result.

🔌 Solder First (Recommended)

Create a solid electrical connection before sealing

For best performance, solder wire connections prior to applying hot glue or silicone.

🧴 Apply Mold Release

Lightly coat jig surfaces before use

Prevents hot glue or silicone from sticking to the jig for clean removal.

🔧 Align Wires

Position wires inside the jig

Keeps wires straight, centered, and stable during sealing.

🔒 Clamp Securely

Close jig to hold splice in place

Holds the connection steady while adhesive is applied.

🔥 Apply Glue or Silicone

Encapsulate the wire connection

Apply hot glue or silicone evenly for waterproof protection.

⏳ Allow to Cure

Let adhesive fully set

Prevents movement for a clean, durable seal.

✅ Remove Finished Splice

Open jig and remove connection

Clean release when mold release or lubricant is used.
