Tesa gasket bronze P sealing tape 9 mm x 25 m for joints and flanges

Tesa Gasket Bronze P sealing tape is a 9 mm wide, 25 m long bronze-coloured strip designed to form flexible gaskets for joints, flanges and pipe connections. The compressible, conformable material fills irregularities at mating surfaces to improve sealing performance against liquids and gases. Intended for use in construction, HVAC, plumbing and maintenance tasks, the tape offers an easy-to-apply solution when traditional cut gaskets are impractical or when on-site adjustments are required.

Advantages

The tape provides a continuous, flexible gasket that adapts to uneven surfaces and small imperfections, reducing the risk of leaks. Its bronze colour helps with visual identification during installation and inspection. The narrow 9 mm width allows use in tight gaps and along small flanges or pipe joints, while the 25 m roll length supplies enough material for multiple small repairs or longer runs. The product is compatible with common sealant and assembly practices used in building services and maintenance work.

Suitable for

• Sealing flange faces and bolted joint interfaces
• Forming gaskets for pipe connections and small-diameter fittings
• On-site gasket repairs and retrofit sealing in HVAC systems
• Temporary or permanent sealing where a compressible strip is needed

Key specifications

• Width: 9 mm
• Length: 25 m
• Colour: bronze
• Form: compressible, conformable sealing tape
• Typical applications: joints, flanges and pipe connections in construction and building services

How to use

Clean and dry the mating surfaces before applying the tape to ensure good contact. Cut the required length from the roll and press the tape into the joint or onto the flange face, ensuring continuous contact along the entire sealing area. Trim any excess flush with the mating surface. Assemble the joint or tighten fasteners according to equipment specifications so the tape is compressed to form a sealing interface. For pipe connections, orient the tape so it fills the intended gap and avoid over-compression that could displace the material.

Usage recommendations

Use the tape in combination with appropriate flanges, gaskets or sealants when specified by system requirements. Verify compatibility with the fluids and temperatures present in the installation; for critical or high-pressure systems, follow applicable industry standards and consider engineered gasket materials if necessary.
