Connection Box Raytech JOULE-MP IP68 — gel-filled electrical junction enclosure

Raytech JOULE-MP IP68 is a gel-filled connection box designed for electrical junctions and splices. The enclosure provides IP68-rated protection against dust and long-term water immersion and uses a silicone gel filling to insulate and seal cable joints. Its compact, robust housing is intended for outdoor and underground use, offering maintenance-free sealing and long-term protection of splices from moisture, corrosion and environmental contaminants.

Advantages

The gel-filled design ensures complete encapsulation of cable joints, eliminating air gaps and reducing the risk of corrosion. An IP68-rated casing provides reliable protection against dust and prolonged submersion in water, while the silicone gel remains stable over a wide temperature range and resists aging. Installation requires no additional potting compound or special tools, and the enclosure supports a variety of cable diameters through flexible entry points.

Suitable for

• Outdoor power cable joints and splices
• Underground cable connections in conduits or direct burial
• Telecommunications and low-voltage distribution where moisture protection is required
• Temporary or permanent installations requiring maintenance-free sealing

Key specifications

• Ingress protection: IP68 for dust-tight performance and prolonged immersion
• Filling material: silicone-based insulating gel for corrosion and moisture resistance
• Application: encapsulation of cable joints and splices for electrical and low-voltage systems
• Installation environment: suitable for outdoor, underground and wet locations
• Operating temperature range: suitable for typical outdoor temperature variations (gel remains stable across wide range)

How to use

Prepare cable conductors and splice them according to standard electrical practice, ensuring clean, mechanically secure connections. Open the enclosure and place the splice inside the gel-filled compartment, positioning conductors to avoid stress on the joint. Close the enclosure following the manufacturer's closure method to ensure a complete seal; the silicone gel will flow to surround the splice, providing insulation and moisture exclusion. After closing, verify the enclosure is intact and, if buried, install at the appropriate depth and location according to installation regulations.

Usage recommendations

Before installation, check that cable sizes and joint types are compatible with the enclosure dimensions and gel volume. Avoid contaminating the gel with solvents or oils, and do not puncture the gel-filled compartment. For buried installations, follow local codes for depth and backfill material. Periodic visual inspection is suggested where accessible, although the product is designed for maintenance-free operation.
