Custom Cleaning Brush
Silicone Tube Brush
Silicone Tube Brush is built for bore, tube, and port where the brush must enter or follow internal walls, threads, and blind holes. Head size, working length, stem flexibility, and fill are selected to loosen chips, oil, and coolant without losing access or control.
Product Features
Soft silicone contact for delicate tubing — Molded fingers clean without stiff bristle ends.
Nonporous surface rinses easily — Silicone releases residue with fewer places for debris to lodge.
Flexible head compresses through openings — The brush adapts to tube diameter and curved passages.
Heat- and chemical-resistant options — Silicone hardness and stem materials can be selected for the cleaning environment.
Metal-free head designs — The working section can avoid exposed wire contact.
Customized to the tube — Head diameter, finger profile, working length, hardness, stem, handle, and color can be developed.
Product Overview
Silicone Tube Brush uses a working section shaped around the available opening, depth, and internal profile. It contacts internal walls, threads, and blind holes to remove chips, oil, and coolant; 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. Brush diameter, working length, tip form, and stem flexibility must match the complete passage.
Key dimensions start with Brush head diameter 3.2–50.8 mm, Brush head length 25–127 mm, and Handle length 152–406 mm. This is a tube-style brush design for controlled contact inside internal passages. The specified interface is threaded removable / fixed. Silicone, PBT, and Polypropylene PP are the principal material directions in the current specification. Choose the handle, neck, and head size so the operator can reach the surface without overloading the bristles.
Technical Specifications

| Contact surface | internal walls, threads, blind holes, cross holes, tapers, ports, and curved passages |
| Residue class | chips, oil, coolant, scale |
| Access and motion | brush diameter, working length, tip form, and stem flexibility must match the complete passage |
| Cleaning duty | bore, tube, port on internal walls, threads, blind holes, cross holes |
| Variant configuration | Silicone Tube Brush: tube construction with Silicone, PBT, Polypropylene PP fill for bore, tube, port, and internal-passage cleaning on internal walls, threads, blind holes, cross holes. |
Application Areas
Silicone Tube Brush is primarily mapped to Tube & Pipe Cleaning. For a new use case, check the surface material, debris flow, and finish requirement before fixing the brush design.
- Silicone Tube 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 internal walls, threads, and blind holes, 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 Silicone, PBT, and Polypropylene PP according to the behavior of chips, oil, and coolant, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. Stiffness is not decided by the material name alone. Filament diameter, free trim length, and density also matter.
When to use another solution
For Silicone Tube Brush, use another cleaning method when chips, oil, and coolant cannot be released by controlled filament contact, when internal walls, threads, and blind holes cannot tolerate the selected contact material, or when the access path prevents safe engagement and residue removal.

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