Sealing tape 3M HT-0020-0032-7, black, heat-resistant to 130°C, 4.5 m × 19 mm

Sealing tape 3M HT-0020-0032-7 is a black, heat-resistant adhesive tape designed for sealing joints, cable entries and insulating surfaces exposed to elevated temperatures. Supplied as a 4.5 m roll with a 19 mm width, the tape provides a compact profile suitable for confined spaces and offers reliable adhesion on common substrates used in electrical and HVAC installations.

Advantages

This sealing tape resists temperatures up to 130°C while maintaining adhesion and dimensional stability. Its narrow 19 mm width and 4.5 m length make it convenient for detailed work and repair tasks in tight areas. The black finish provides a discreet appearance and helps hide joints and cable runs. The tape's backing and adhesive system are selected to deliver consistent performance on plastics, metal and cable sheaths typically found in maintenance and installation work.

Suitable for

• Sealing small joints and gaps in HVAC systems
• Insulating and securing cable entries and splices
• General maintenance and repair where heat resistance is required

Key specifications

• Color: black
• Heat resistance: up to 130°C
• Length: 4.5 m
• Width: 19 mm
• Format: single roll

How to use

Ensure the surface is dry, clean and free of dust, oil and loose particles before application. Measure and cut the required length, then press the tape firmly onto the substrate to achieve full contact and good adhesion. Overlap adjacent turns slightly when wrapping cables or sealing seams to form a continuous barrier. For curved or irregular surfaces, apply in short segments and smooth each segment to avoid air pockets. Allow the adhesive to set under normal conditions before subjecting the repair to mechanical stress or elevated temperatures.

For best results, store the tape in a cool, dry place away from direct sunlight and apply at temperatures recommended for adhesive activation. Avoid using the tape on surfaces contaminated with silicone or heavy oils. If long-term outdoor exposure is required, consider additional protective measures since prolonged UV exposure can affect appearance and adhesive life.
