The Twist Seal is a reliable and user-friendly alternative to traditional lead seals and sealing wire. This seal is ideal for gas, electricity, and water meters and consists of a transparent body, a plastic-coated galvanized steel wire (300 mm), and a colored plastic locking cylinder. When the yellow cylinder is twisted, both wire ends are securely clamped inside the housing, making removal impossible without visible damage. After sealing, the yellow tab is broken off to prevent tampering. Each Twist Seal is laser-marked with a unique number for easy registration and enhanced security.
Tamper evidence through transparent housing
The clear body of the Twist Seal provides full visibility of the locking mechanism. Any tampering attempt is immediately noticeable. The internal cylinder rotates in only one direction, ensuring the seal cannot be loosened or reopened without breaking.
Tamper prevention via break-off tab
Once the seal is locked, the yellow tab on the outer housing must be broken off. This prevents any undetected adjustments and guarantees the integrity of the seal during long-term use.
300 mm plastic-coated steel wire for durability
The built-in galvanized steel wire has a length of 300 mm and a 1 mm diameter, coated with plastic for added flexibility and corrosion resistance. This design ensures reliability even in humid or industrial environments.
Modern, tool-free sealing solution
Unlike traditional lead seals that require a tool and separate wire, the Twist Seal can be applied completely by hand. This saves time and increases safety. The unique serial number also enables easy and secure tracking—something not possible with conventional lead seals.
Applications: meters and technical installations
The Twist Seal is suitable for sealing gas, water, and electricity meters, as well as technical cabinets or equipment containing sensitive components. Thanks to the thin 1 mm wire, it fits easily through narrow openings. Note: The installation of seals on utility meters may only be carried out by certified professionals in consultation with the network operator.
Unique numbering and imprint
Each Twist Seal is marked with the standard text “TSN SEAL” and a unique sequential number. Navacqs and the manufacturer guarantee that each combination is produced only once, ensuring traceability and preventing fraud.
