Custom Cleaning Brush
Narrow Tube Brush
Narrow 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
Slim cylindrical head enters restricted passages — The brush cleans tubes and ports with limited internal diameter.
Radial bristles provide complete wall contact — Twisted-wire construction cleans around the circumference.
Flexible and rigid stem options — Different cores suit straight and gently curved tubes.
Filament selected for residue and surface — Nylon, PBT, or polypropylene can be specified according to moisture, chemical exposure, and tube sensitivity.
Protected tip options — Loops and caps reduce scratching and snagging.
Sized to the narrow passage — Diameter, working length, filament, stem, tip, and connection can be customized.
Product Overview
Narrow 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. The brush is built around a tube or bore structure for internal-wall cleaning. The specified interface is threaded removable / fixed. PBT, Polypropylene PP, and Nylon PA are the principal material directions in the current specification. The handle and head proportions should let the user reach the area while keeping brush pressure under control.

Application Areas
Narrow Tube Brush is primarily mapped to Tube & Pipe Cleaning. Before switching to a new application, make sure the surface, debris path, and finish requirement are clearly defined.
- Narrow 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 PBT, Polypropylene PP, and Nylon PA according to the behavior of chips, oil, and coolant, 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 Narrow 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 Narrow 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 Narrow 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 Narrow Tube Brush?
The primary options are PBT, Polypropylene PP, and Nylon PA. The final choice follows surface sensitivity, residue adhesion, wet or dry use, temperature, chemicals, conductivity, and required cutting action.
When is Narrow Tube Brush not the best cleaning method?
Narrow 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 Narrow 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 PBT, Polypropylene PP, and Nylon PA, quantity, and the existing interface or sample.
