Nastro isolante Tesa 4163-07-07, bianco, 50 mm × 33 m

Tesa insulating tape 4163-07-07 in white is an adhesive-backed electrical tape measuring 50 mm × 33 m designed for insulation, protection and bundling of cables and electrical connections. The tape provides a wide coverage area that speeds up wrapping and reduces the number of joins needed on larger-diameter cables. It is formulated for general electrical maintenance, repairs and installations in workshops, homes and professional environments where a reliable, non-conductive tape is required.

Advantages

The tape combines a conformable backing with stable adhesive performance to ensure secure adhesion to various cable surfaces and insulation materials. Its 50 mm width allows efficient coverage of joints and connectors, while the 33 m roll length offers multiple uses before replacement. The white colour enables visual identification, neat finishes and easy masking of labels or markings underneath. The material offers basic resistance to abrasion and moisture typical for standard electrical tapes intended for indoor and covered outdoor use.

Suitable for

• Insulating electrical splices and joints
• Bundling and securing cable runs
• Temporary repairs on damaged insulation
• Marking and colour-coding where a white tape is required
• General maintenance in workshops, households and light industrial settings

Key specifications

• Width: 50 mm
• Length: 33 m
• Colour: white
• Type: adhesive electrical insulating tape
• Typical use: insulation, bundling, protection of cables and connectors

How to use

Ensure surfaces are clean, dry and free from oil, dust or loose particles before application. Start the wrap slightly overlapping the beginning of the area to be insulated, then stretch the tape lightly and apply with consistent tension while rotating the cable or moving the roll to produce an even, overlapping layer. For joints and splices, overlap each turn by approximately half the tape width to create a uniform insulating layer. Use scissors or a sharp cutting tool to trim the end and press the final edge down to secure adhesion.

Recommendations

Use this tape for indoor electrical work and covered outdoor applications. For high-temperature environments, long-term outdoor exposure, or applications requiring specific flame-retardant or high-voltage ratings, choose a tape specified for those conditions. Store rolls at room temperature away from direct sunlight and abrasive surfaces to maintain adhesive performance.
