HellermannTyton HIS-A 3:1 tubo termorretrátil com revestimento adesivo, transparente, 3 mm/1 mm, 10 m caixa distribuidora 308-10303

Electrical connections exposed to moisture, corrosion, and mechanical stress need reliable insulation and sealing. The HellermannTyton HIS-A heat shrink tubing solves this with a dual-wall design: an outer cross-linked polyolefin jacket and an inner adhesive lining that melts during shrinking to create a waterproof, strain-relieved seal.

Who is it for

This tubing is ideal for electricians, panel builders, automotive technicians, and maintenance engineers who need to protect splices, connectors, and wire harnesses in demanding environments. The transparent colour allows visual inspection of the underlying connection after shrinking.

Main features

• 3:1 shrink ratio recovers to one-third of its original diameter, conforming tightly to irregular shapes.
• Adhesive lining provides environmental sealing and mechanical strain relief.
• Supplied in a convenient dispenser box for easy storage and length cutting.
• Transparent wall permits inspection of the sealed connection.

Tips

For best results, use a heat gun set to the recommended shrink temperature and apply heat evenly around the tubing until the adhesive flows and the tubing fully recovers. Ensure the surface is clean and dry before application.
