Custom Cleaning Brush
PBT Cleaning Brush
PBT Cleaning Brush is built for material-specific custom brush construction where the brush must enter or follow the specified part surface, edge, and bore. Head size, working length, stem flexibility, and fill are selected to loosen dust, oil, and particles without losing access or control.
Product Features
Stable Stiffness During Wet Cleaning — PBT’s low water absorption helps the bristles maintain consistent contact inside tubes and passages.
Full-Circumference Internal Contact — Radial fill cleans the complete wall of pipes, nozzles, bottles, and cylindrical components.
Good Rinse and Drying Behavior — The filament releases water more readily than highly absorbent fibers and supports repeated wash cycles.
Chemical-Resistant Option for Process Cleaning — PBT can be selected for detergents and many industrial fluids after actual compatibility is confirmed.
Rigid or Flexible Stem Options — The brush can be built for straight bores, gentle bends, blind holes, or long internal passages.
Made to the Passage — Brush diameter, working length, PBT filament size, stiffness, stem, tip, handle or thread can be customized.
Product Overview
PBT Cleaning Brush uses a working section shaped around the available opening, depth, and internal profile. It contacts the specified part surface, edge, and bore to remove dust, oil, and particles; 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 brush geometry must be defined together with filament diameter, trim, density, wet or dry condition, and the required interface.
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. PBT are the principal material directions in the current specification. The handle, neck, and head geometry should make the target easy to reach while keeping contact pressure manageable.
Technical Specifications

| Variant configuration | PBT Cleaning Brush: tube construction with PBT fill for material-specific custom brush construction on the specified part surface, edge, bore, panel. |
Application Areas
PBT Cleaning Brush is primarily mapped to Tube & Pipe Cleaning. Before changing the application, review the contact surface, debris removal path, and acceptable surface condition.
- PBT Cleaning 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 the specified part surface, edge, and bore, the available access, and manual operation. 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 PBT according to the behavior of dust, oil, and particles, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. Choose stiffness by looking at filament size, free trim length, and density together with the material.
When to use another solution
For PBT Cleaning Brush, use another cleaning method when dust, oil, and particles cannot be released by controlled filament contact, when the specified part surface, edge, and bore cannot tolerate the selected contact material, or when the access path prevents safe engagement and residue removal.

Frequently Asked Questions
How should PBT Cleaning 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 PBT Cleaning 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 PBT Cleaning Brush?
The primary options are PBT. The final choice follows surface sensitivity, residue adhesion, wet or dry use, temperature, chemicals, conductivity, and required cutting action.
When is PBT Cleaning Brush not the best cleaning method?
PBT Cleaning 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 PBT Cleaning 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 PBT, quantity, and the existing interface or sample.
