Simple & Secure Installation in 6 Steps
A perfect seal is easy to achieve. Follow these steps for a connection that lasts.
01
Prepare the Wires
Strip approximately 1/2 inch (12 mm) of insulation from each wire. For stranded wires, twist the strands together tightly. Ensure copper is clean and straight.
02
Align and Insert Wires
Hold the stripped wire ends evenly together. Push them firmly into the silicone-filled cap until they bottom out.
03
Twist to Secure
Grip the outer shell and twist it clockwise onto the wires. The internal spring will bite into the conductors, creating a secure mechanical and electrical connection. Continue until hand-tight.
04
Confirm the Connection
Gently tug on each wire individually. A proper installation will prevent any wire from pulling loose.
05
Engage the Waterproof Seal
This step seems to be missing from the original text but is crucial for this style of connector. If your model has a secondary sealing cap, press it firmly over the connector body until it snaps into place. [If this is not the case for your models, this step can be removed].
06
Final Check
Visually inspect the connector to ensure wires are fully seated and the seal is engaged. The connection is now waterproof, corrosion-resistant, and ready for installation.

Frequently Asked Questions (FAQ)
What makes Tonful wire nuts truly waterproof (IP68)?
Our connectors use a three-point defense: a durable outer shell, precision-engineered threads, and a pre-filled silicone sealant. This combination displaces air and moisture, creating a seal rated IP68 for continuous submersion.
Can I use these for direct burial underground?
Yes. All our waterproof models shown here are UL Listed for direct burial applications, making them code-compliant for underground splices.
What's the difference between "water-resistant" and "waterproof"?
“Water-resistant” might handle a splash, but “waterproof” means it can be fully submerged. Our IP68-rated connectors are designed for continuous immersion, providing the highest level of protection.
Are Tonful waterproof wire nuts reusable?
To guarantee a perfect waterproof seal, our gel-filled connectors are designed for a single, permanent installation. Reusing them can compromise the integrity of the silicone sealant.
Can I use these with both solid and stranded wire?
Yes, our wire nuts are designed with a flexible internal spring that securely grips both solid and stranded copper conductors within the specified wire range.
