Custom Cleaning Brush
Cannula Cleaning Brush
Cannula Cleaning Brush is built for medical instrument and channel cleaning where the brush must enter or follow instrument joints, lumens, and channels. Head size, working length, stem flexibility, and fill are selected to loosen protein residue, lubricant, and detergent film without losing access or control.
Product Features
Very small diameter for narrow lumens — Fine cylindrical heads enter cannulas and small medical passages.
Radial bristles clean the full internal wall — The brush removes residue around the complete circumference.
Controlled tip finishing — Rounded, looped, or protected ends reduce scratching and perforation risk.
Stem stiffness matched to the cannula — Rigid or flexible constructions can suit straight and gently curved devices.
Size identification and controlled packaging — Diameter markings and pack format can help match the brush to the intended cannula.
Made to the cannula — Lumen diameter, working reach, brush-section length, stem stiffness, filament, tip, handle, and packaging can be specified.
Product Overview
Cannula Cleaning Brush uses a working section shaped around the available opening, depth, and internal profile. It contacts instrument joints, lumens, and channels to remove protein residue, lubricant, and detergent film; 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 must match channel diameter and length while avoiding exposed sharp ends and trapped filament.
Key dimensions start with Brush head diameter 1–6 mm, Brush head length 10–35 mm, and Handle length 178–305 mm. The brush uses a bore-cleaning structure matched to the diameter, depth, and access path. The specified interface is threaded removable / fixed. PA6 Nylon, PA612 Nylon, and Nylon PA are the principal material directions in the current specification. Set the handle and head proportions around the working distance, access angle, and the level of contact control required.

Application Areas
Cannula Cleaning 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.
- Cannula 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 instrument joints, lumens, and channels, the available access, and manual operation. Confirm Brush head diameter 1–6 mm, Brush head length 10–35 mm, and Handle length 178–305 mm against the complete working envelope before finalizing the brush.
Contact material
Choose from PA6 Nylon, PA612 Nylon, and Nylon PA according to the behavior of protein residue, lubricant, and detergent film, 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 Cannula Cleaning Brush, use another cleaning method when protein residue, lubricant, and detergent film cannot be released by controlled filament contact, when instrument joints, lumens, and channels cannot tolerate the selected contact material, or when the access path prevents safe engagement and residue removal.

Frequently Asked Questions
How should Cannula 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 lumen diameter, working reach, and Brush section, choose the fill from the material and residue table, and match the mounting interface and operating condition.
Which dimensions define Cannula Cleaning Brush?
The primary dimensions are lumen diameter (1–6 mm), working reach (178–305 mm), and Brush section (10–35 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 Cannula Cleaning Brush?
The primary options are PA6 Nylon, PA612 Nylon, and Nylon PA. The final choice follows surface sensitivity, residue adhesion, wet or dry use, temperature, chemicals, conductivity, and required cutting action.
When is Cannula Cleaning Brush not the best cleaning method?
Cannula 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 Cannula Cleaning Brush?
Send the part or machine drawing, photos of internal wall, thread, blind hole, cross hole, taper, pipe, membrane housing, and narrow cavity, lumen diameter, working reach, Brush section, and Stem diameter, the residue description, wet or dry conditions, motion or use method, temperature, preferred PA6 Nylon, PA612 Nylon, and Nylon PA, quantity, and the existing interface or sample.
