RayTech MAMMUT-GEL IP68 2-Pole Gel Junction Box for Cable Connections up to 4 mm², 450V/24A, Outdoor & Underground

Electricians working on outdoor lighting or underground cable runs need a junction box that can handle moisture, dirt, and the occasional submersion. The RayTech MAMMUT-GEL IP68 junction box seals 2-pole connections in a non-toxic silicone gel that never hardens, so you can re-open and re-work the joint as needed. With a 450 V / 24 A rating and support for 1.5–4 mm² cables, it is a practical choice for garden, pond, and buried installations.

Key specifications

• IP68 protection: dust-tight and submersible up to 1 m
• 2-pole straight or branch connection
• Cable cross-section: 1.5 mm² to 4 mm²
• Cable diameter range: 6.5 mm to 12 mm
• Rated voltage: 450 V; rated current: 24 A
• Re-enterable, non-toxic silicone-based gel
• Polypropylene (PP) housing, halogen-free and UV resistant
• Operating temperature: -20 °C to +90 °C
• Certifications: CE, EN 50393

Why choose it

The gel-filled design eliminates the need for resin mixing or heat-shrink sleeves. Simply strip the cables, insert them into the terminals, and close the lid — the gel flows around the connection and cures to a waterproof seal. If you need to modify the circuit later, the gel remains soft and can be re-entered without damaging the box or the cables. The compact PP housing withstands UV exposure and soil chemicals, making it suitable for direct burial or outdoor mounting.

Ideal use cases

• Outdoor lighting junctions (garden, path, deck)
• Underground cable splices for irrigation or pumps
• Submersible connections in ponds or fountains (up to 1 m)
• Re-workable joints in maintenance-prone installations

Good to know

The gel is non-toxic and remains flexible over time, allowing multiple re-entries without loss of protection. The box is halogen-free, so it emits no corrosive gases in case of fire, and its UV-resistant PP body ensures long service life even in direct sunlight.
