Flexible Nylon Strip Brush | Cut to Length Door & Conveyor Seal

Flexible Strip Brush — Nylon Seal Brush Strip with PVC Backing

Product Introduction

Gaps under doors, along machine ways and beside conveyor belts are hard to seal with rubber. They let in dust, light and drafts, but they also need to keep moving parts and workpieces passing through. That is exactly what a flexible nylon strip brush is built for.

This strip brush packs dense nylon filaments into a PVC backing channel. The filaments flex on contact and spring back, sweeping the gap clean instead of blocking it. The result is a dust-tight, light-tight seal that still lets doors slide, belts run and parts move.

Supplied by the meter and cut to length on request, it fits door bottoms, CNC way covers, conveyor frames, escalator entries and cabinet edges without custom tooling. Filament color in black, transparent/white, red or custom shades; backing channel color can be matched to your equipment.

Advantages

• Sweeps, doesn't block — Flexible nylon filaments bend around obstructions and recover, sealing while parts pass.
• Dense tuft packing — Even bristle density along the full length means no weak spots in the seal.
• Nylon that lasts — PA6 / PA66 / PBT filament resists oil, moisture and abrasion under continuous use.
• PVC backing holds shape — Rigid channel keeps bristles aligned; no splaying or pull-out over time.
• Cut to length on site — No need to order exact pre-cut sizes; trim, drill and screw on installation day.
• Color-matched options — Black, white, red filament and backing to blend into the machine or door

FAQ

Q1: How do I measure the right strip brush length?

Measure the full edge you need to seal — door bottom, machine opening or conveyor side. The brush is supplied by the meter and cut to your exact size, so order slightly longer if you want a margin for trimming on site.

Q2: Can I screw the strip brush directly to a door?

Yes. The PVC backing can be drilled and screwed directly, or riveted, along the edge. For high-wear or sliding applications, sliding the backing into an aluminum holder is recommended.

Q3: What bristle length do I need?

Bristle trim length depends on the gap size. As a rule, the bristle should extend about 10–15 mm past the gap to make firm contact. Send us your gap dimension and we will recommend the trim length.

Q4: Will the nylon bristles flatten over time?

Nylon has good memory and springs back after compression. For heavy continuous contact, choose a stiffer filament (higher denier or PA66) rather than the soft standard grade.

Q5: Can I get a UV-resistant version for outdoor use?

Yes. Standard nylon is fine indoors; for outdoor or sunlight exposure, specify UV-stabilized nylon or PBT filament when ordering.
