IP68 Waterproof Junction Box – 1kV Submersible Cable Seal
IP68 Waterproof Junction Box – Submersible Cable Potting Seal
Protect your underground or outdoor cable connections with this heavy-duty IP68-rated waterproof junction box. Engineered with potting compound filling technology, this submersible cable seal enclosure completely encases cable connection points, keeping moisture, water, and environmental contaminants out — ideal for buried installations, garden lighting, LED strips, landscape wiring, and outdoor electrical projects.
Made in Mainland China.
Key Features
- IP68 Waterproof Rating: Full submersion protection achieved through potting compound filling technology that creates a complete, watertight seal around cable connection points.
- Superior Insulation: High-grade potting compound and junction box housing deliver excellent insulation resistance, reducing the risk of leakage and protecting both personnel and equipment.
- Corrosion-Resistant Shell: Constructed from modified PP (polypropylene) plastic with acid and alkali resistance for extended service life in harsh or buried environments.
- Quick & Easy Installation: Simply pull off the partition strip on the aluminum foil bag to mix the potting compound — no splashing, no overflow, no mess.
- High Compressive Strength: Sturdy, impact-resistant housing withstands external force compression and ground pressure, keeping internal connections secure and intact.
- 1kV Voltage Rating: Suitable for standard low-voltage cable sealing applications including LED light strips, garden and landscape wiring, and buried cable runs.
- Transparent Design: Clear housing lets you visually verify the potting compound fill without disassembly.

Frequently Asked Questions
Q: What does IP68 rated mean for this waterproof junction box?
A: IP68 is the highest standard for waterproof protection, indicating the junction box can withstand continuous submersion in water beyond 1 meter depth for extended periods. The potting compound filling technology completely seals all cable connection points, making this box fully suitable for buried underground and submerged outdoor applications.
Q: Is this junction box suitable for LED light strip outdoor installations?
A: Yes — this IP68 waterproof junction box is specifically designed to protect cable connection points for LED light strips, garden lighting, and landscape wiring that are exposed to rain, irrigation, or direct burial underground. Its 1kV voltage rating covers standard low-voltage LED strip wiring.
Q: How do I use the potting compound to seal the junction box?
A: Simply pull off the partition strip on the included aluminum foil bag to combine the two-part potting compound. Place your cable connections inside the box, pour the mixed compound in, and allow it to cure. The formula is designed for no-splash, no-overflow installation, making it easy even for first-time users.
Q: What size junction box do I need?
A: Two sizes are available. The small box measures 180 × 40 × 45 mm (approx. 7.09 × 1.57 × 1.77 in) and weighs 175g — suitable for compact cable joins. The large box measures 270 × 55 × 55 mm (approx. 10.63 × 2.17 × 2.17 in) and weighs 365g — better for thicker cables or multiple-wire connections.
Q: Can this junction box handle acidic or alkaline soil conditions?
A: Yes. The housing is made from high-quality modified PP (polypropylene) plastic, which offers excellent resistance to acids and alkalis, making it well-suited for direct burial in a variety of soil types without degradation over time.
