Waterproof Electrical Connection Protection for Demanding Environments
Techno Gel Gum is a two-component insulating and sealing compound designed to protect power cable, telecom cable, and electronic circuit connections from moisture, corrosion, vibration, and environmental exposure.
With IP68 protection in proper casings, Techno Gel Gum helps create a strong waterproof barrier around electrical connections exposed to water, humidity, dust, and demanding outdoor conditions. By sealing and insulating the connection, it helps reduce the risk of corrosion, electrical faults, and premature connection failure.
Its unique formulation combines the characteristics of gel and rubber, offering the flexibility of gel with the toughness and dry surface characteristics of rubber. The result is a re-enterable sealing compound that supports long-term protection while still allowing access for maintenance or inspection.
Its vibration-resistant structure can also act as a mechanical damper, helping protect connections from movement, vibration, and mechanical stress.

Choose the Right Raytech Product
Use this guide to compare Raytech waterproof electrical protection products by application, serviceability, and installation method.
Magic Gel
Best for: general waterproof potting and electrical insulation.
Choose Magic Gel when you need a dielectric gel for filling an enclosure, junction box, or electrical connection while keeping future access possible.
Magic Power Gel
Best for: reusable waterproof protection.
Choose Magic Power Gel when future access and reusability matter. It is a strong option when the connection may need to be opened and resealed later.
Techno Gelgum
Best for: vibration damping and mechanical hold.
Choose Techno Gelgum when the connection is exposed to movement, vibration, mechanical stress, or demanding submerged conditions. Even suitable for high depths under water.
Magic Rubber
Best for: stronger mechanical structure.
Choose Magic Rubber when you need more structure than a soft gel, but do not want to permanently encapsulate the connection with hard epoxy.
Magic Gel Sprint
Best for: fast curing waterproof potting and electrical insulation.
Choose Magic Gel Sprint when you need a re-enterable dielectric gel with a faster curing time for quicker installations or faster return to service.
Ray Gel
Best for: transparent or UV-resistant waterproof protection.
Choose Ray Gel when you need a low-viscosity dielectric gel with transparent or UV-resistant protection for electrical connections, junction boxes, or installations exposed to UV.
Wonder Gel
Best for: overhead and hard-to-reach junction boxes.
Choose Wonder Gel when you need a ready-to-use cartridge gel for overhead, vertical, or hard-to-reach junction boxes where pouring is difficult or not practical.
Prefilled Gel Boxes
Best for: wire connectors and terminal blocks.
Choose prefilled gel boxes when you want a ready-to-use solution for protecting wire connectors or terminal blocks without mixing, pouring, or curing.
