Pull Tight Seals

Pull tight seals are the most multifunctional seals Navacqs offers. They are available in various versions, such as smooth, serrated, or flat sealing tails. These seals are easy to apply and can be pulled tight for a secure closure. Once removed, they cannot be reused. Due to their design variety, they are suitable for both light and heavy-duty applications, ranging from mail shipments to freight transport and medical use.

About pull tight seals

Pull tight seals are used to detect unauthorised access to items such as containers, fire extinguishers, medical kits, and transport units. They are indicative seals – meaning they don’t form a physical barrier but clearly show if they have been broken. Depending on the application, you can choose between seals with high or low breaking strength. This ensures the right solution for safety, traceability, or access control.

Every seal is unique

Each pull tight seal from Navacqs is unique thanks to a combination of company logo or custom text and a sequential number. This imprint is produced only once, making copying or reuse impossible. Both Navacqs and the manufacturer guarantee the exclusivity of the imprint. This prevents fraud and ensures the reliability and traceability of each seal.

Indicative seals

Pull tight seals belong to the category of indicative seals. They signal whether an item has been opened but are not designed to resist forced entry. Their purpose is to indicate, not to block. This makes them ideal for situations where quick visual inspection is needed, such as in transport, healthcare, or logistics – making them highly effective in daily use.

Breaking strength

The breaking strength of pull tight seals ranges from 4 to 40 kg. Seals with lower breaking strength are suitable for emergency uses, such as fire hose reels or medical equipment, and can be broken by hand. Stronger seals (10–25 kg) are more resistant to force and are often used for trucks, containers, drums, and roll cages. The appropriate strength depends on the desired level of control and application.

Seal tail

Navacqs supplies pull tight seals with different types of tails. A smooth tail is ideal for use where snagging must be avoided. Serrated tails (also called rat tails) provide extra grip when tightening. Flat tails combine strength and ease of use, making them suitable for heavy-duty applications. The choice of tail influences both handling and breaking strength of the seal.

Applications

Pull tight seals are suitable for a wide variety of uses. They are used to seal trucks, IBC containers, mailbags, collection boxes, medical equipment, and more. In warehouses, logistics, transport, and healthcare they offer fast and visible control. Thanks to the variety in design and strength, there is always a suitable seal for every environment and requirement.
