The Mini Seal 140 is a compact plastic security seal specifically designed for securing the safety pin of fire extinguishers. With an ultra-thin sealing tail of only 1.7 mm in diameter, the seal can easily pass through the narrow hole of the safety pin. It has a low breaking strength of just 2 kg, allowing it to be quickly and easily broken by hand in an emergency. The Mini Seal 140 is available from stock in four bright colors: red, yellow, blue, and green.
The Mini Seal 140 is designed to be removed instantly in the event of an emergency. With a breaking strength of only 2 kg, it is the weakest seal in the Navacqs range. It is comparable to the Extin 2 Seal, which has a slightly higher strength of 6 kg. Thanks to this low resistance, the seal can be broken manually without any tools, ensuring quick access when needed.
The Mini Seal 140 features an exceptionally thin sealing tail of 1.7 mm, making it suitable for applications where space is limited. The smooth surface allows for easy application without damaging the surrounding area. This makes it ideal for fire extinguishers but also useful wherever a light, narrow seal is required.
This seal is specifically developed for securing the safety pins of fire extinguishers. When the pin is removed to operate the extinguisher, the seal automatically breaks, clearly indicating whether the extinguisher has been used. During annual inspections by certified companies, the seal is replaced as proof of approval and readiness.
Despite its small size, the Mini Seal 140 features a large flag measuring 25 by 20 mm. This makes the seal clearly visible even from a distance. The flag offers ample space for customization, such as adding a company name, logo, or certification mark, which is ideal for fire safety and inspection companies.
The Mini Seal 140 is supplied as standard without imprint or numbering but can be customized on request. Printing with a logo or sequential numbering is available from 1,000 pieces and can be ordered in red, yellow, blue, or green.
The Mini Seal 140 is a practical, reliable, and user-friendly security seal that combines safety with convenience.
You can make the Mini Seal 140 even more distinctive by adding your own custom print. It is possible to include your logo or company name on the seal. Below are the customization options:

A seal for a fire extinguisher needs to be thin, fit easily through the safety pin, and be breakable by hand immediately. A light plastic seal with a low breaking strength is used for this.
The Mini Seal 140 is suitable thanks to its thin 1.7 mm seal tail and low breaking strength of 2 kg. This is the lightest seal for fire extinguishers. It stays in place until use, but breaks immediately when the safety pin is pulled out.
Key features:
thin seal tail
low breaking strength
opens by hand
A seal for a fire extinguisher must not delay use and needs to make it visible whether the extinguisher has been used. That's why the seal needs to be light, flexible and easy to break.
The Mini Seal 140 meets this with a breaking strength of 2 kg and a narrow tail. This ensures the safety pin can be removed without resistance in an emergency.
Points to watch:
breaking strength (low)
diameter of the seal tail
free movement of the safety pin
The Mini Seal 140 is a plastic pull-tight seal (a seal you insert through an opening and pull tight) with a breaking strength of 2 kg, specifically for fire extinguishers. The seal has no unique number. It's used to see at a glance whether the fire extinguisher has already been used or opened.
The thin 1.7 mm seal tail fits through the safety pin of a fire extinguisher. The large flag makes it visible whether the seal is intact after inspection.
Applications:
safety pins of fire extinguishers
objects with very small openings
A Mini Seal 140 without numbering is used when only visual inspection is needed, without registration per seal. The goal is to quickly see whether a fire extinguisher has been checked and remains unused.
In situations where no records are kept per seal, a simple seal without numbering is sufficient and practical to use.
Typical situations:
visual inspection after servicing
locations without a registration requirement
applications with large numbers of seals
A Mini Seal 140 has a breaking strength of 2 kg. This is the lowest breaking strength in the range, meaning the seal can be broken by hand immediately.
The low breaking strength comes from the thin 1.7 mm seal tail. This keeps the seal in place during normal use, but lets it break without force when the safety pin is removed.
Comparison:
Mini Seal 140: 2 kg
Extin 2: around 5 kg
