Junction box Raytech SUPER-BLOCK-3 IP68 gel-filled connection enclosure

Raytech SUPER-BLOCK-3 is a gel-filled connection enclosure designed to protect inline splices and terminations in demanding environments. The unit provides an IP68-rated waterproof and dustproof seal around cable joints, using a non-hardening insulating gel that maintains flexibility and dielectric protection over time. The compact enclosure accommodates various cable sizes and configurations, enabling secure electrical and cable connections for outdoor, underground and marine installations.

Advantages

The gel-filled design ensures continuous moisture exclusion and electrical insulation without hardening or shrinking, reducing the risk of stress on conductors and seals. IP68 protection guarantees long-term resistance to water ingress and dust, making the enclosure suitable for submerged or buried applications. The enclosure's construction supports straightforward installation and reliable environmental sealing while preserving access to cable joints if future maintenance is required.

Suitable for

• Outdoor power and signal cable splices exposed to weather
• Buried or ducted cable joints requiring moisture protection
• Marine and coastal installations with saltwater exposure
• Temporary or permanent inline terminations needing flexible insulation

Key specifications

• Protection class: IP68 for waterproof and dustproof sealing
• Filling: non-hardening insulating gel for long-term moisture exclusion
• Application: indoor/outdoor, underground and marine use
• Compatibility: accommodates a range of cable diameters and splice configurations
• Material properties: resilient enclosure body designed for mechanical protection and environmental resistance

How to use

Prepare cable ends and complete electrical connections or splices following standard electrical safety practices. Place the mated conductors and any required insulating tape or spacers into the enclosure body, then fill or position the non-hardening gel around the joint as specified by the manufacturer's instructions. Close the enclosure and ensure a secure seal to achieve IP68 protection. Verify the integrity of joints and seals before burying or exposing the enclosure to water or severe weather.

Usage recommendations

Use suitable personal protective equipment and follow applicable electrical codes during installation. Select the appropriate enclosure orientation and cable entry arrangement for strain relief and to minimize water pooling. For long-term submerged installations, periodically inspect surrounding infrastructure; if maintenance is required, the gel allows joint access without damaging the insulating medium.
