Sealing
Technical definition
Sealing using industrial brushes is a technical solution designed to close or protect spaces between moving or fixed elements in machinery, industrial installations, or infrastructures. This function is based on the use of dense filaments that form a flexible barrier capable of limiting the passage of dust, particles, light, or contaminants between two areas.
Unlike other rigid sealing systems, such as rubber seals, industrial brushes help maintain tightness without impeding the movement of mechanical components. The flexibility of the filament allows it to adapt to irregularities, vibrations, or displacements of the system without generating excessive friction or premature wear.
On the other hand, they have a limited sealing capacity for air and liquids since it must not be forgotten that it is an industrial brush with filaments and therefore, there will always be a small gap between them.
Brush sealing is widely used in industrial machinery, transport systems, technical doors, protection cabins, and material handling equipment. Thanks to their adaptability and durability, sealing brushes contribute to helping improve the energy efficiency of equipment, reducing the entry of contaminants, and protecting production processes.
Types of brush for industrial sealing
The brushes used for sealing applications can adopt different configurations depending on the type of installation, the space to be protected, and the environmental conditions of the process.
| Brush type | Main application | Recommended filament | Format |
|---|---|---|---|
| Strip sealing brush | Sealing of doors, machinery and gaps between machines | Polypropylene, PBT, PA | Plastic strip |
| Cylindrical sealing brush | Sealing in rollers or rotating equipment | Nylon, polypropylene | Custom-made |
| Flat sealing brush | Protection of panels and surfaces | Nylon (polyamide) | Rectangular or square base |
Strip sealing brushes
Strip brushes are the most common solution for sealing applications in industrial environments. They are made up of filaments fixed in a slender, elongated plastic profile, which allows their installation on doors, guides, panels, or machinery structures.
Their function is to create a flexible barrier that limits the passage of dust, air, or particles between two areas. This type of brush is frequently used in industrial doors, material transport equipment, or machinery protection systems.
The density of the filament and its length are adjusted according to the space to be sealed and the working conditions.
Cylindrical sealing brushes
Cylindrical brushes can also be used for sealing applications in rotating machinery or systems where there are moving elements that require protection.
The filament surrounds the axis of the brush forming a continuous barrier that limits the passage of dust or residues into the equipment. This solution is used in transport machinery, material handling equipment, or systems where rollers pass through separation zones.
Flat sealing brushes
Flat brushes are used when it is necessary to seal wide surfaces or industrial panels. This type of brush allows covering large areas creating a flexible barrier between two surfaces.
They are frequently used in protection cabins, isolation systems, or industrial equipment where it is required to control the air flow or the entry of particles.
Applications by sector
Sealing using industrial brushes is used in numerous sectors where it is necessary to protect equipment, prevent the entry of contaminants, or improve the insulation of installations.
Food industry
In food production facilities, sealing brushes are used to limit the entry of dust or contaminants into machinery and processing areas.
They are also used in industrial doors or transport systems to maintain proper hygienic conditions within the facilities.
Packaging industry
In automated packaging lines, sealing brushes help prevent the entry of dust or residues into sensitive equipment, which contributes to maintaining the quality of the final product.
They are also used to seal openings in machinery and protect mechanical components.
Glass industry
In glass handling processes, sealing brushes allow protecting the equipment against glass particles or dust generated during the manufacturing process.
This helps to prolong the useful life of the machinery and improve working conditions.
Transport and logistics industry
In logistics centers and automated goods transport systems, sealing brushes are used to protect conveyor belts, automatic doors, and handling equipment against the entry of dust or dirt.
Energy and industrial machinery
In industrial equipment and energy systems, sealing brushes help protect components against the entry of particles, improve the tightness of the equipment, and reduce energy losses caused by leaks.
Technical selection of the sealing brush
The selection of an industrial brush for sealing applications must be made taking into account various technical factors related to the working environment and the function it must fulfill.
One of the most important aspects is the size of the space to be sealed. The length and density of the filament must be adjusted to adequately cover the gap without generating excessive friction.
It is also necessary to consider the relative movement between the surfaces to be sealed. In applications with moving elements, the brush must allow displacement without suffering premature wear.
The environmental conditions of the process also influence the selection of the filament material. In environments with the presence of humidity, chemicals, or high temperatures, specific materials with greater specialization may be required.
In certain industrial applications, regulatory requirements related to hygiene, safety, or compatibility with food must also be taken into account.
Finally, the fixing system of the brush must adapt to the structure of the machinery to guarantee a safe and durable installation.

FAQ
What are industrial sealing brushes used for?
Sealing brushes are used to close spaces between machinery elements or industrial installations, preventing the passage of dust, air, particles, or contaminants.
What type of brush is used to seal industrial doors?
Strip brushes with aluminum profiles are one of the most common solutions for sealing industrial doors, as they allow covering the space between the door and the floor or the frame.
Do sealing brushes allow the movement of equipment?
Yes. The flexibility of the filaments allows maintaining the seal while the mechanical components move, which makes them especially useful in industrial machinery.
Can sealing brushes be custom-made?
Yes. Industrial sealing brushes are usually custom-made to adapt to the dimensions of the machinery and the specific requirements of each application.
Are brushes suitable for sealing liquids or gases?
They are not the most suitable equipment for this since they offer a limited seal. The brush is made up of filaments, there will always be a gap between them, so they have a limited sealing capacity.
