Flexible Strip Brush — Nylon Seal Brush Strip with PVC Backing

Product Introduction

A flexible strip brush is a continuous linear brush made by packing dense nylon filaments into an extruded PVC backing channel. The backing keeps every bristle row aligned and prevents pull-out, while the flexible bristle tufts bend and recover to maintain even contact along the whole edge.

Unlike a rigid rubber seal, a flexible brush strip seals by sweeping. It allows moving parts, belts or workpieces to pass through while still blocking dust, light and drafts. This is why flexible strip brushes are the standard choice for door sealing, machine way protection and conveyor light cleaning.

This product uses uniform nylon filament tufts anchored firmly inside a PVC/PP backing strip. The bristle filling is dense and even along the full length, giving consistent contact pressure from end to end. Filament color is available in black, transparent/white, red and custom shades; the backing channel can also be color-matched to your equipment shell.

Advantages

• Flexible sweeping seal — Nylon filaments bend and spring back, sealing gaps without blocking material flow.
• Dense, even filling — Consistent contact pressure along the full length for reliable dust and light blocking.
• Wear-resistant nylon — PA6 / PA66 / PBT options resist oil, moisture and most mild chemicals.
• Rigid PVC backing — Dimensionally stable, easy to cut, drill, screw or slide into a holder on site.
• Color matching — Filament and backing in black, white, red or custom colors.
• Cut to length — Produced by the meter; bristle diameter and trim length configurable.

FAQ

Q1: What is a flexible strip brush used for?

A flexible strip brush seals gaps and blocks dust along doors, machine enclosures, conveyor frames and sliding tracks. It also lightly cleans conveyor belts, guides products and acts as a weather strip.

Q2: Why is it called a flexible brush strip?

Because the nylon filaments bend and recover under contact pressure. It sweeps rather than blocks, allowing moving parts or workpieces to pass through while still sealing the gap.

Q3: What are the bristles made of?

The bristles are nylon filaments, usually PA6 or PA66. They are elastic, wear-resistant and resistant to oil and moisture for continuous light-contact use.

Q4: Can the flexible strip brush be cut to length?

Yes. It is produced in continuous lengths and can be cut to your exact required size on site. Backing profile, bristle diameter and bristle length can also be customized.

Q5: How do I install it?

The PVC backing channel can be screwed, riveted or slid into a matching holder along the edge to be sealed. It can also be cut and drilled directly on site.

Q6: Is it suitable for outdoor use?

Nylon filament is weather and UV resistant to a degree. For long-term outdoor exposure, UV-stabilized or PBT filament can be recommended — please confirm your working condition when ordering.
