Cable accessory HellermannTyton 416-14047, polyolefin black, diameter 3.2 cm, pack of 300

HellermannTyton 416-14047 is a black polyolefin cable accessory designed as a thermoplastic end cap with adhesive lining. With an outer diameter of 3.2 cm and supplied in a pack of 300 pieces, this product is intended for sealing, protecting and finishing cable ends in low-voltage installations. The construction is suitable for use on polymeric and paper insulated cables, including those with lead jackets and metallic armouring such as aluminium or steel. The adhesive-backed polyolefin provides a heat-shrinkable, weather-resistant closure that secures the cable termination against moisture and mechanical wear.

Advantages

The thermoplastic adhesive lining ensures a reliable seal after heat shrinking, while the polyolefin material gives mechanical robustness and resistance to environmental factors. The standardised 3.2 cm diameter simplifies selection for cables of matching size, and the bulk pack of 300 items supports larger installations or stocking for repeated maintenance. Compatibility with both polymeric and paper insulated, lead-jacketed and armoured cables allows use across diverse wiring systems.

Suitable for

• Sealing and protecting ends of low-voltage power cables
• Cable terminations in electrical distribution and control panels
• Industrial wiring where mechanical protection and moisture sealing are required
• Field splicing and finishing of polymeric or paper insulated cables with lead jackets or metal armouring

Key specifications

• Material: polyolefin with thermoplastic adhesive lining
• Color: black
• Diameter (nominal outer): 3.2 cm
• Heat-shrinkable ratio: up to 3:1 (thermally activated shrinkage)
• Pack quantity: 300 pieces
• Intended voltage range: low-voltage cable applications

How to use

Select an end cap with adequate diameter to fit over the cable and any armouring or lead jacket. Position the sleeve over the cable end so the adhesive-lined section covers the exposed insulation and jacket. Apply controlled heat using a suitable heat gun or shrinker, moving the heat source evenly to activate shrinkage and melt the adhesive. Continue heating until the sleeve has uniformly contracted and the adhesive forms a continuous seal around the jacket and insulation. Allow the assembly to cool before mechanical handling.

Recommendations

For reliable performance, follow manufacturer guidelines for shrink temperatures and heating distance. Pre-clean cable surfaces of contaminants and ensure any sharp edges on armour are de-burred or covered to avoid damaging the sleeve. Use appropriate personal protective equipment during shrink application and verify the final seal visually and, where required, with moisture or electrical insulation checks.
