Silicone Sleeves
Silicone sleeves for neon tubes provide reliable electrical and mechanical protection for connections and electrodes. They ensure dielectric insulation for high-voltage contacts and protect them against moisture, dust, and oxidation. Thanks to their high elasticity and temperature resistance, they guarantee safe installation and a long service life for illuminated lettering and neon contours in indoor and outdoor environments.

List of products
The liner serves as a protection against dangerous contact voltage and must be covered with all connections.
Type I sleeve - Straight cable outlet from the back of the sleeve.
Type II sleeve (reverse) - Reverse cable lead around the electrode, the sleeves are suitable for lines where the tubes are together.
FAQ – Frequently Asked Questions
What are silicone sleeves used for in neon signs and signmaking?
Silicone sleeves are protective and insulating components placed over the ends or joints of neon tubes, electrodes, and wiring. Their primary role is to protect sensitive connections from moisture, dust, weather conditions, and to provide electrical insulation for high-voltage parts. This significantly extends the lifespan of the entire lighting installation.
What are the main advantages of using silicone for these sleeves?
Silicone stands out for its high flexibility, long service life, and extreme resistance to temperature fluctuations, UV radiation, and aging. Unlike ordinary plastics, it does not harden, crack, or lose its sealing properties even when used outdoors in demanding weather conditions.
How do I choose and correctly install a silicone sleeve?
When choosing, it is crucial to select the correct diameter and shape of the sleeve that precisely matches the dimensions of the tube or electrode to form a tight and secure joint. Installation is very simple—the sleeve is simply slipped over the prepared joint or tube end, where, thanks to its elasticity, it holds firmly and performs its protective and insulating functions.
