Junction box Raytech SUPER-BLOCK-IN-OUTW IP68 — gel-sealed connection enclosure for cables

Raytech SUPER-BLOCK-IN-OUTW is an IP68-rated gel-sealed junction box designed to provide a compact, weatherproof enclosure for electrical and signal cable splices. The unit uses a silicone gel filling to encapsulate and insulate cable joints, preventing ingress of water, dust and corrosive elements. Its robust outer body and watertight sealing make it suitable for outdoor, buried and exposed installations where a small, maintenance-free connection point is required.

Advantages

The gel-sealed design ensures long-term protection against moisture and contaminants without the need for mechanical seals or additional potting. The enclosure is rated to IP68 for complete immersion resistance when properly installed. A compact footprint and simple cable entry scheme allow rapid installation in confined or crowded spaces. The silicone gel provides electrical insulation and prevents oxidation of conductors, extending the service life of splices in harsh environments.

Suitable for

• Outdoor branch and spur connections for power and low-voltage circuits
• Telecom cable splices and signal line terminations
• Underground or ducted installations requiring immersion resistance
• Temporary or permanent connections in industrial and utility networks

Key specifications

• Ingress protection: IP68 when correctly installed
• Sealing medium: silicone gel for encapsulation and insulation
• Application: power, telecom and low-voltage cable splices
• Installation environment: outdoor, buried, ducted and exposed locations
• Body: robust weather-resistant enclosure suitable for immersion

How to use

Prepare cable ends by stripping insulation to the appropriate length for the chosen splice method. Place the prepared splice inside the enclosure and position cables through the designated entry points. Add or allow the silicone gel to flow around the joint ensuring complete encapsulation of conductors and insulation. Close the enclosure following manufacturer guidance to achieve the IP68 seal. Verify that cable routing and closure are correct before backfilling or exposing the box to wet conditions.

Usage recommendations

Use compatible splice types and follow accepted electrical practices for conductor preparation and connection. Ensure the enclosure is installed on stable, dry substrate and that the gel completely covers the splice to maintain IP68 performance. For buried installations, avoid placing heavy loads directly over the enclosure and comply with local codes for cable depth and protection.
