Nylon Copper Sealing Wire – 1 mm, Spiral
Nylon copper sealing wire combines a nylon core with a copper spiral, so it stays both sturdy and extremely flexible. Because the nylon core softens the wire's surface, it will not accidentally injure the user during handling — a clear advantage over all-metal wires. As a result, your team can seal quickly and comfortably, even at high volume.
The wire measures 1 mm in diameter, and a 0.6 mm nylon core carries a 0.3 mm annealed copper spiral wound around it. Moreover, the copper element keeps it spark-free, so it suits refineries and fuel-handling sites especially well. It also threads smoothly and locks securely once you fit the seal.
In addition, it works with all types of wire security seals, including twist seals and meter seals for electricity, gas and water. At LPX Trade, we dispatch it quickly from Liepāja, Latvia, and we deliver across the Baltics and the wider European Union.

- Transport and logistics
- High-volume sealing where safe handling matters
- Any setting that needs a flexible, user-friendly wire
Frequently asked questions
What makes nylon copper sealing wire different?
A nylon core replaces the usual metal core, so the wire feels softer and will not accidentally injure the user. Yet the copper spiral still keeps it spark-free and secure.
What diameter and shape does it have?
It measures 1 mm in total diameter and takes a spiral form. Specifically, a 0.6 mm nylon core carries a 0.3 mm annealed copper wire wound around it at 66 coils per 100 mm.
Is it safe for fuel handling?
Yes. Because copper does not spark, it suits refineries and fuel-handling environments where steel wire would pose a risk.
Which seals does it work with?
It works with all types of wire security seals, including twist seals and meter seals for electricity, gas and water.
