Aluminium seal leads are stronger and more durable than traditional lead versions. They are often used together with stainless steel sealing wire, forming a combination that is resistant to moisture, corrosion, and harsh weather conditions. This makes aluminium seal leads ideal for long-term sealing applications, both indoors and outdoors. They are compatible with the NZT-1P sealing plier and stainless steel sealing wire and are supplied in bags of 1,000 pieces.
Unlike traditional soft lead seals, these seal leads are made from durable aluminium. The material offers excellent resistance to humidity, saltwater, and extreme temperatures, making it suitable for use in demanding environments such as ships, offshore platforms, and outdoor installations. Aluminium is also more robust than lead, which makes these seals harder to deform or damage.
To complete the seal, sealing wire is required. While galvanized steel wire can be used, stainless steel sealing wire is strongly recommended for long-term or outdoor applications. The combination of aluminium seal leads and stainless steel sealing wire ensures a corrosion-resistant, tamper-proof seal that remains secure even under tough conditions.
Each bag contains 1,000 aluminium seal leads. The compact and lightweight packaging makes them easy to transport and convenient to store. The quantity provides sufficient supply for continuous sealing work in the field or workshop.
Aluminium seal leads are particularly suitable for use in humid locations such as water meter rooms or areas exposed to rain and seawater. They offer long-lasting protection and make tampering immediately visible. These seals are an excellent choice for utility meters, containers, and industrial installations that require durable and weather-resistant sealing.

Aluminium seals are used when the seal needs to stay in place for a long time and withstand load and weather conditions.
Unlike plastic seals, aluminium seals are harder and less prone to deformation. This keeps them intact better during prolonged use outdoors or in industrial environments.
They're used for:
outdoor installations
damp spaces
industrial applications
Aluminium seals are harder than lead seals and more resistant to moisture and wear.
Lead is softer and easier to crimp shut, but deforms faster and is less suitable for prolonged outdoor use.
Aluminium requires slightly more force to crimp, but stays intact better afterward.
Yes, aluminium seals are suitable for outdoor use and damp environments. The material withstands rain, condensation and temperature fluctuations.
This keeps them usable for:
water meters
outdoor installations
applications in industry or offshore
Aluminium seals are often combined with stainless steel sealing wire because both materials withstand moisture and corrosion.
This combination means the entire seal is suitable for prolonged use outdoors or in wet conditions.
With standard steel wire, the wire can start to rust, making it less strong.
Aluminium seals are harder and stronger than plastic seals. This makes them more suitable for long-term applications and situations where the seal is under tension.
Plastic seals are mainly chosen for their colour and recognizability, while aluminium is used when durability and mechanical strength matter more.
