Tesa rubber sealing tape D-profile H0538900 for 3–7 mm gaps, 0.009 x 25 m

Tesa rubber sealing tape D-profile H0538900 is a flexible sealing solution designed to close gaps between 3 and 7 mm. The product is supplied as a continuous rubber strip with a D-shaped cross-section and an adhesive backing, measuring 0.009 x 25 m. It forms a consistent, compressible seal for doors, windows and other joints, helping to reduce drafts, dust penetration and moisture ingress while improving thermal and acoustic insulation in renovation and maintenance applications.

Advantages

The D-profile rubber tape provides reliable elasticity and shape retention, adapting to uneven surfaces and maintaining contact under repeated compression. Its self-adhesive backing allows for straightforward, tool-light installation on clean, dry surfaces. The material resists typical household wear and contributes to reduced energy loss and lower noise transfer through gaps. The compact dimensions make it suitable for discreet installation along frames and sashes.

Suitable for

• Sealing gaps around doors and windows with 3–7 mm clearances
• Weatherproofing renovation work and routine maintenance
• Reducing drafts, dust ingress and minor moisture penetration
• Improving thermal and acoustic insulation at frame joints

Key specifications

• Profile type: D-shaped rubber seal
• Gap capacity: 3–7 mm
• Dimensions: 0.009 m (thickness) x 25 m (length)
• Backing: self-adhesive for surface mounting
• Material: flexible rubber with compressible cross-section

How to use

Measure the gap to confirm compatibility with the 3–7 mm range. Clean and dry the surface thoroughly to remove dust, grease and loose paint; use an appropriate cleaner and allow full drying. Cut the required length from the roll, peel off the adhesive liner and press the tape firmly into position along the frame or joint, ensuring continuous contact and avoiding air pockets. Trim excess material with a sharp blade and apply even pressure along the installed length to secure the adhesive bond. Allow the adhesive to set before subjecting the seal to heavy mechanical stress.

Recommendations

For best results, install at temperatures recommended for pressure-sensitive adhesives (typically above 10 °C). Replace any old or damaged seals before applying the tape to ensure proper adhesion. Avoid installing on wet or contaminated surfaces and test a small area if bonding to painted or delicate finishes. Periodically inspect the seal for compression set or wear and replace when no longer effective.
