The Sealing Wire 50/30 Spool is the most commonly used sealing wire in the Navacqs range. It consists of two intertwined steel strands, providing extra grip and strength. When used with lead seals and sealing pliers, it offers a highly reliable sealing method. The 50/30 wire is made of galvanized steel, has a breaking strength of 7 kg, and is suitable for applications such as gas, electricity, and water meters. It is available in bundles of 100 meters and 400 meters.
The name 50/30 refers to the composition of the wire: a 0.5 mm steel core wrapped with a 0.3 mm outer wire. This double-strand structure ensures excellent grip, locking the wire firmly inside the lead seal once crimped with pliers. Once sealed, the wire cannot be moved or reused, effectively preventing tampering, a risk often present with smooth steel or cord.
The sealing wire is supplied on compact bundles that are easy to handle and transport. The wire can be cut to any required length. The 90-meter bundle is convenient for regular use, while the 360-meter version is ideal for high-volume applications. Additionally, pre-cut wire bundles of 1,000 pieces are available in lengths of 20, 30, or 40 cm.
Sealing Wire 50/30 is used together with lead seals and a sealing press. Both ends of the wire are threaded through the seal, which is then crimped closed with pliers. The braided texture prevents the wire from being pulled back, ensuring a secure, tamper-evident seal.
The wire is made from galvanized steel, resistant to moisture and corrosion. With a breaking strength of 7 kg, it offers sufficient durability for seals that must not be opened by hand. A lighter version, Sealing Wire 20/20, has a breaking strength of 1.7 kg and is suitable for low-tension or emergency applications.
With its thin 1.1 mm diameter, this sealing wire is ideal for securing gas, electricity, and water meters, as well as technical or industrial equipment. Installation may only be performed by certified technicians in consultation with the network operator. For applications where sealing pliers are not desired, the Twist Seal is a suitable alternative. Note: Private individuals are not permitted to replace seals in meter cabinets without prior authorization from the network operator.

Sealing wire on a reel is chosen when the required length varies per application. You cut the wire to size yourself, making it suitable for both short and longer seals.
For fixed lengths or repetitive work, bundles are more practical, but a reel offers more flexibility on site.
Sealing wire 50/30 has a breaking strength of around 7 kg. This means the wire can't be broken by hand, but can be cut with tools.
The combination of a core wire (0.5 mm) and a wrapped wire (0.3 mm) means the wire clamps firmly inside the seal.
This prevents the wire from being pulled back after sealing.
The sealing wire is threaded through the openings of a seal. The ends are then fed through the seal and crimped shut with sealing pliers.
Once crimped, the wire is fixed in place and can no longer be shifted or pulled back.
Steps:
cut the desired length
thread the wire through the seal
crimp the seal shut with sealing pliers
