Electrical tape Hellermann Tyton 712-00503

Hellermann Tyton 712-00503 electrical tape is a general-purpose insulating tape designed for professional and DIY electrical work. The tape is 50 m long, 19 mm wide and 0.31 mm thick, providing a balanced combination of coverage and flexibility. It offers reliable insulation and protection for wiring, cable joints and terminations and is formulated to resist moisture and many common chemicals, allowing use in a range of indoor and outdoor environments.

Advantages

The tape provides consistent dielectric insulation and mechanical protection while remaining flexible enough to conform to irregular shapes and tight bends. Its thickness and width deliver reliable coverage for splices and cable bundles without excessive bulk. Resistance to moisture and chemicals reduces the risk of degradation in damp or contaminated conditions. The product is compatible with common cable types and can be applied by hand or with standard tape dispensers.

Suitable for

• Insulating electrical splices and terminations
• Bundling and securing cable runs
• Temporary repairs and protective wrapping for wires
• Indoor and outdoor installations where moisture resistance is required

Key specifications

• Length: 50 m
• Width: 19 mm
• Thickness: 0.31 mm
• Material characteristics: moisture-resistant and chemical-resistant insulating film
• Flexibility: conforms to irregular shapes and tight bends

How to use

Ensure surfaces are clean, dry and free from oil or heavy contamination before application. Start wrapping at one end of the splice or cable, overlapping each turn by approximately half the tape width to create a continuous insulating layer. Apply moderate tension while wrapping to eliminate air gaps and ensure good adhesion; smooth the tape with your fingers to promote full contact. For outdoor or long-term applications, extend the wrap beyond the exposed area and overlap onto intact insulation to form a reliable seal.

Usage recommendations

Store the tape in a cool, dry place away from direct sunlight and sources of heat. Use within the manufacturer's recommended storage period to preserve adhesive performance. For permanent joints or high-voltage applications, follow applicable electrical codes and consider complementary protective measures such as heat-shrink tubing or mechanical connectors.
