HellermannTyton Heat Shrink Tubing 28mm to 4.7mm Black 3:1 HFT-A

The HellermannTyton 151-28469 is a high-quality heat shrink tubing from the HFT-A series, designed for professional electrical insulation, mechanical protection, cable bundling, and strain relief. With a supplied internal diameter of 28 mm and a recovered internal diameter of 4.7 mm, this tubing offers a 3:1 shrink ratio, making it ideal for a wide range of applications. Made from cross-linked polyolefin, it is flexible, flame retardant (self-extinguishing), and UV resistant (black colour). It operates reliably in temperatures from -55°C to +135°C and requires a minimum shrink temperature of +90°C.

Advantages

This heat shrink tubing provides excellent dielectric strength (>20 kV/mm) and good chemical resistance against common fluids and solvents. It meets RoHS and UL 224 VW-1 standards, ensuring safety and compliance. The black colour offers UV protection, extending the life of the installation in outdoor or harsh environments.

Suitable for

• Electrical insulation of wires and cables
• Mechanical protection for connectors and terminals
• Cable bundling and organization
• Strain relief for cable assemblies
• Automotive, industrial, and marine applications
