Sealing tape Tesa PRO 62822 — self-vulcanizing butyl rubber, 10 m × 19 mm, black

Tesa PRO 62822 is a self-vulcanizing sealing tape made from butyl rubber, supplied in a 10 m roll with a 19 mm width and a black finish. The tape bonds to itself without requiring adhesive activation, forming a flexible, continuous seal that resists moisture and adapts to irregular surfaces. It is designed for indoor and outdoor sealing tasks where a conforming, long-lasting barrier against water and air infiltration is needed.

Advantages

The tape forms a cohesive, vulcanized joint after application, eliminating the need for additional adhesives. Its butyl rubber composition provides elasticity and durability across temperature variations, while the black surface offers UV resistance suitable for exposed installations. The narrow 19 mm width allows use in confined spaces and precise sealing work, and the 10 m length reduces the number of splices for long runs.

Suitable for

• Sealing cable entries and conduit connections
• Waterproofing roof flashings and small repairs
• Overlapping plumbing joints and pipe penetrations
• Temporary or permanent sealing of seams and joints in building envelopes

Key specifications

• Material: self-vulcanizing butyl rubber
• Roll length: 10 metres
• Width: 19 millimetres
• Colour: black
• Application: indoor and outdoor sealing

How to use

Ensure the surfaces to be sealed are clean, dry and free of loose material, oils or dust. Unroll the tape and wrap it tightly around the joint or penetration, overlapping successive turns to achieve a continuous layer. Apply tension during wrapping so the tape bonds to itself and vulcanizes over time to form a single, cohesive seal. Trim the tape with a suitable cutting tool after applying the required number of turns.

Usage recommendations

For best performance, apply at moderate temperatures and allow adequate overlap when wrapping around irregular profiles. Use on sound substrates and avoid stretching the tape beyond recommended handling to maintain seal integrity. Where permanent exposure to strong solvents or extreme mechanical abrasion is expected, consider additional protective measures.
