Product Overview
The Flexible Brush Seal is a staple-set strip brush designed for sealing applications where a rigid brush profile cannot easily follow curved, irregular or uneven surfaces. Nylon bristle tufts are securely fixed into a flexible rubber profile using metal staples, creating a durable brush seal that can bend and conform to different installation shapes.
Compared with conventional metal channel strip brushes, the flexible backing provides greater installation freedom and can be supplied in long continuous lengths. The bristle density, trim height, profile shape and overall dimensions can be customized according to the required sealing performance and mounting conditions.
This flexible rubber profile brush is commonly used for dust, splash and debris control on industrial equipment, vehicles, production lines and other applications requiring an adaptable sealing edge.
Product Features
- Flexible Rubber Profile – The flexible backing can bend around curved, irregular and uneven surfaces, allowing the brush seal to adapt to installation areas where rigid metal channel brushes are difficult to use.
- Staple-Set Construction – Nylon bristle tufts are mechanically secured into the rubber profile with staples for reliable retention and stable performance during use.
- Adjustable Bristle Density – Available with 1, 2 or 3 rows of bristle tufts to provide different levels of sealing density according to the application.
- Multiple Profile Shapes – Different rubber profile configurations, including F profile and h-shaped profile, are available to suit different mounting structures.
- Long Continuous Lengths – The standard supply length is 25 meters per continuous strip, allowing customers to cut the brush to the required length during installation. Longer continuous lengths can also be manufactured upon request.
- Custom Bristle Height – Bristle trim height can be customized up to 600 mm for different sealing gaps and equipment requirements.

Materials
Flexible Rubber Profile: The backing is made from flexible rubber, allowing the brush to bend and follow curved, irregular or uneven mounting surfaces. Different profile shapes and dimensions can be customized according to the installation structure.
Nylon Bristles: Nylon bristles provide good flexibility, resilience and wear resistance for industrial sealing applications. Bristle height, density, color and arrangement can be customized according to the required sealing performance.
Metal Staples: The nylon bristle tufts are mechanically fixed into the rubber profile using metal staples. This staple-set construction provides secure bristle retention while maintaining the flexibility of the overall brush.
Applications
Flexible brush seals are suitable for applications where a conventional rigid strip brush cannot easily follow curved, uneven or irregular mounting surfaces. The flexible rubber profile can conform to different shapes while the nylon bristles provide a continuous brush barrier for sealing, splash control and debris protection.
- Data Centers and Server Racks – Used around cable openings, floor penetrations and equipment gaps to help control airflow, dust and debris.
- Trucks and Buses – Installed around wheel areas and body openings as a flexible splash guard to help reduce mud, water spray and road debris.
- Agricultural Machinery – Used on sprayers and other agricultural equipment for flexible shielding, spray control and debris protection.
- Production Lines and Machinery – Suitable for sealing along curved, irregular or moving equipment edges where rigid strip brushes are difficult to install.
- Custom Industrial Sealing – Can be adapted to enclosures, guards, openings and other applications requiring a long, flexible brush barrier.

Quality Control
Each flexible brush seal is inspected during production to ensure consistent dimensions, bristle density and secure tuft retention. We pay particular attention to the connection between the nylon bristle tufts and the flexible rubber profile, as reliable bristle retention is essential for long-term sealing performance.
Bristle pull tests are performed to check the holding strength of the staple-set tufts and help ensure that the bristles remain securely fixed in the rubber profile during normal use.
Frequently Asked Questions
What is a flexible brush seal?
A flexible brush seal is a strip brush with bristle tufts fixed into a flexible rubber profile. Unlike a rigid metal channel strip brush, the flexible backing can bend and follow curved, irregular or uneven surfaces, making it suitable for applications where a rigid brush is difficult to install.
What is the difference between F profile and h-shaped profile brush seals?
The main difference is the cross-sectional shape of the flexible rubber profile and how it fits the mounting structure. F profile and h-shaped profile brush seals are designed for different installation configurations. Profile dimensions can also be customized to match the customer’s equipment or mounting requirements.
Can the flexible brush seal be cut to the required length?
Yes. The standard supply length is 25 meters per continuous strip, and customers can cut the brush to the required length during installation. Longer continuous lengths can also be manufactured upon request.
How are the bristles fixed into the rubber profile?
The nylon bristle tufts are mechanically secured into the flexible rubber profile using metal staples. This staple-set construction provides reliable tuft retention while allowing the complete brush seal to remain flexible.
Can the bristle height and density be customized?
Yes. Bristle trim height, tuft density and the number of bristle rows can be customized according to the sealing gap and application requirements. We can manufacture flexible brush seals with 1, 2 or 3 rows of bristle tufts, with trim heights up to 600 mm.
