Sealing tape Tesa 4042448099402 brown for 2–5 mm gaps, 0.009 x 1 m

Tesa sealing tape in brown is a narrow, compressible rubber strip designed to close gaps between 2 and 5 mm. Supplied as a 0.009 x 1 m roll, this sealing tape creates a flexible seal for windows, doors and joints to reduce drafts and limit moisture ingress. The product is intended for straightforward DIY repairs and routine maintenance where a slim, resilient seal is required.

Advantages

The tape is made from a compressible elastomer that conforms to uneven surfaces and maintains contact under light pressure, providing a consistent sealing function in narrow gaps. Its slim profile and 1 m roll length make it easy to handle and cut to size for precise application. The brown colour blends with wooden frames and darker surfaces, and the material resists typical household conditions encountered in window and door installations.

Suitable for

• Sealing narrow gaps between window frames and sashes (2–5 mm)
• Reducing drafts around exterior and interior doors
• Filling joints in furniture or cabinetry where a thin compressible seal is needed
• Temporary or permanent sealing of small openings to limit moisture and dust ingress

Key specifications

• Material: compressible rubber/elastomer
• Colour: brown
• Gap range: suitable for 2–5 mm clearances
• Dimensions: 0.009 m thickness × 1 m length (roll)
• Form: compressible strip supplied on a roll for cutting to length

How to use

Ensure the surfaces to be sealed are clean, dry and free of loose debris or dust. Measure the gap and cut the required length from the roll. If necessary, compress the strip slightly and insert it into the gap so that it fills the clearance evenly; trim excess material flush with the surface. For best results, press the tape into place along the full length of the joint to ensure consistent contact and sealing performance.

Usage recommendations

Store the roll in a cool, dry place away from direct sunlight. For long-term exterior use, inspect seals periodically and replace if the material shows signs of hardening, cracking or permanent deformation. When applying the tape to painted or sensitive surfaces, test a short sample area first to confirm compatibility.
