The NSS-530 Padlock Seal combines a stainless steel shackle with a high-strength plastic housing, creating a compact and exceptionally strong seal. Thanks to its robust construction and convenient design, it is ideal for securing lockers, storage boxes, rental equipment, and other valuable goods. Each seal is supplied with a unique, sequential number that is produced only once, ensuring full traceability and tamper evidence.
Safety and reliability are key features of the NSS-530 Padlock Seal. The housing is made from Polyacetal (POM), a material known for its strength, dimensional stability, and low friction properties. It performs exceptionally well in moving parts and applications exposed to mechanical stress or frequent use. The shackle is manufactured from high-quality stainless steel with a diameter of only 1.2 mm. Despite its small size, it provides remarkable strength, especially when combined with the durable POM housing.
While the seal is designed for maximum strength and security, it is also easy to apply. The NSS-530 can be locked with a single click. Once closed, it cannot be opened by hand. A cutting tool is required to remove the seal, as it has a breaking strength of 40 kg. For applications where a lower breaking strength is sufficient, Navacqs also offers fully plastic alternatives such as the One Piece Padlock Seal and the PL5 Padlock Seal, which can be opened manually.
The NSS-530 Padlock Seal is ideal for securing lockers, storage boxes, and containers with valuable contents. Its strong stainless steel shackle prevents unauthorized access, making it highly suitable for environments where both security and durability are essential. It can also be used to seal rental items such as helmets or clothing. The compact form and easy application make it a practical and secure solution for a wide range of uses.
Each NSS-530 Padlock Seal is standardly printed with the text “SEALED” and a unique sequential number. Both Navacqs and the manufacturer guarantee that every combination is produced only once. This provides traceability and helps detect or prevent tampering and fraud.
It is possible to make the NSS-530 Padlock Seal even more distinctive by adding a custom print. For example, you can include your company name or logo on the seal. The table below lists the specific customization options available for the NSS-530 Padlock Seal.

The NSS-530 padlock seal is one of the strongest padlock seals thanks to the combination of a polyacetal housing and a 1.2 mm stainless steel shackle, with a breaking strength of 40 kg. This makes it a seal that can't be opened by hand and can only be removed with tools.
The high breaking strength comes from the steel shackle instead of a fully plastic build. Plastic padlock seals typically have a breaking strength of around 6 kg and can be broken by hand.
This type is used when the seal must not be openable by hand, for example on crates with valuable contents or lockers. The seal prevents anyone from removing it without tools.
A padlock seal with a stainless steel shackle, such as the NSS-530, has a metal closure and a breaking strength of 40 kg, while a plastic padlock-style seal is made entirely of plastic and typically has a breaking strength of around 6 kg. Plastic variants can be opened by hand; the NSS-530 can't.
The difference lies in material and application. Plastic seals are used for quick access, for example on first aid kits. The NSS-530 is used when unauthorized opening needs to be actively prevented.
The choice depends on whether the seal needs to be opened quickly by hand (for example for first aid) or should only be removable with tools to prevent unauthorized access.
A padlock seal with a stainless steel shackle is used when a seal not only needs to show tampering, but also needs to offer physical resistance to opening. The steel shackle prevents the seal from being removed by hand.
Typical applications are situations with an increased risk of unauthorized access or theft.
Examples:
lockers with personal or valuable contents
crates and transport boxes
rental items such as helmets or clothing
In these situations, a plastic seal isn't sufficient due to its low breaking strength.
The NSS-530 padlock seal has a breaking strength of 40 kg. This means a pulling force of around 40 kilograms is needed to break the seal, which in practice isn't achievable without tools.
The strength comes from the combination of a polyacetal housing and a 1.2 mm thick stainless steel shackle. These materials withstand mechanical load and repeated use of the locking mechanism.
This keeps the seal intact under normal use and transport.
No, the NSS-530 padlock seal can't be opened by hand. Because of the stainless steel shackle and 40 kg breaking strength, cutters or similar tools are needed to remove the seal.
This prevents users or unauthorized persons from opening and reclosing the seal unnoticed. Breaking it always leaves visible damage.
This makes the NSS-530 suitable for applications requiring controlled access.
