Custom Cleaning Brush
Flexible Rod Brush
Flexible Rod Brush is built for duct, vent, and chimney where the brush must enter or follow duct walls, dryer vents, and flues. Head size, working length, stem flexibility, and fill are selected to loosen lint, soot, and dust without losing access or control.
Product Features
Flexible shaft follows curves and offsets — The brush reaches pipes, ducts, channels, and hidden passages.
Radial head cleans the full internal wall — Bristles surround the core for circumferential contact.
Different rod lengths and connections — Sectional, continuous, threaded, and quick-connect systems can be supplied.
Filament selected for residue and surface — Nylon or polypropylene can be specified for routine wet or dry passage cleaning.
Protected tip options — Loops and caps reduce snagging and scratching.
Flexible-rod set matched to the route — Diameter, rod length, flexibility, fill, tip, connection, and kit contents can be customized.
Product Overview
Flexible Rod Brush uses a working section shaped around the available opening, depth, and internal profile. It contacts duct walls, dryer vents, and flues to remove lint, soot, and dust; the access path and minimum clearance determine whether the brush needs a rigid stem, a flexible extension, a tapered head, or a stepped cleaning section. The flexible rod, brush diameter, joint, working length, and bend radius must reach the complete passage without separating.
Key dimensions start with Brush head diameter 3.2–50.8 mm, Brush head length 25–127 mm, and Handle length 152–406 mm. The design follows a tube and bore-brush format for radial contact on internal surfaces. The specified interface is threaded removable / fixed. Nylon PA and Polypropylene PP are the principal material directions in the current specification. The stroke, guide clearance, and flexible length must be checked against the complete movement envelope.

Application Areas
Flexible Rod Brush is primarily mapped to Tube & Pipe Cleaning. Before applying the brush to another process, verify the surface, the route for removed debris, and the final finish target.
- Flexible Rod Brush is best suited to tube, pipe, bore, hole, thread, cannula, housing, membrane, and internal-passage cleaning.
- The twisted-in-wire, flexible-rod, pull-through, fan-tip, or powered bore brush follows internal wall, thread, blind hole, cross hole, taper, pipe, membrane housing, and narrow cavity while the fill displaces scale, rust, chips, burrs, oil, coolant, deposits, powder, and biological residue.
- Use this configuration when the available access supports radial filament contact inside a bore, tube, hose, channel, nozzle, or drilled passage.
Selection Guidance
Structure fit
Match the tube & pipe bore brush geometry to duct walls, dryer vents, and flues, the available access, and reciprocating motion. Confirm Brush head diameter 3.2–50.8 mm, Brush head length 25–127 mm, and Handle length 152–406 mm against the complete working envelope before finalizing the brush.
Contact material
Choose from Nylon PA and Polypropylene PP according to the behavior of lint, soot, and dust, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. Brush stiffness depends on the material plus filament diameter, free trim length, and fill density.
When to use another solution
For Flexible Rod Brush, use another cleaning method when lint, soot, and dust cannot be released by controlled filament contact, when duct walls, dryer vents, and flues cannot tolerate the selected contact material, or when the access path prevents safe engagement and residue removal.

Frequently Asked Questions
How should Flexible Rod Brush be selected?
Start with tube, pipe, bore, hole, thread, cannula, housing, membrane, and internal-passage cleaning, internal wall, thread, blind hole, cross hole, taper, pipe, membrane housing, and narrow cavity, and scale, rust, chips, burrs, oil, coolant, deposits, powder, and biological residue. Then set brush diameter, Brush section, and Overall length, choose the fill from the material and residue table, and match the mounting interface and operating condition.
Which dimensions define Flexible Rod Brush?
The primary dimensions are brush diameter (3.2–50.8 mm), Brush section (25–127 mm), and Overall length (152–406 mm). Also provide the minimum clearance, working envelope, trim or engagement, and the existing holder, shaft, stem, thread, or handle.
Which filament or contact material is used for Flexible Rod Brush?
The primary options are Nylon PA and Polypropylene PP. The final choice follows surface sensitivity, residue adhesion, wet or dry use, temperature, chemicals, conductivity, and required cutting action.
When is Flexible Rod Brush not the best cleaning method?
Flexible Rod Brush is not the first choice for pigs, flushing, ultrasonic, chemical descaling, blasting, or a flexible cable system for long, sharply curved, or heavily scaled passages.
What information is required to quote Flexible Rod Brush?
Send the part or machine drawing, photos of internal wall, thread, blind hole, cross hole, taper, pipe, membrane housing, and narrow cavity, brush diameter, Brush section, Overall length, and Filament diameter, the residue description, wet or dry conditions, motion or use method, temperature, preferred Nylon PA and Polypropylene PP, quantity, and the existing interface or sample.
