Custom Cleaning Brush
20mm P320 AO Tube Brush
20mm P320 AO Tube Brush is built for Heat Exchanger Tube Internal Cleaning 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
20 mm brush diameter suits small process tubes and bores — The head maintains full-wall contact.
P320 aluminum-oxide filament provides finer abrasive action — The brush can clean, deburr, and lightly finish without the coarse cut of lower grits.
Flexible abrasive bristles conform to minor bore variation — Contact remains less rigid than a honing stone.
Radial fill distributes finishing around the circumference — The complete inner wall is treated.
Fine abrasive grade supports controlled surface refinement — Useful where heavy stock removal is not required.
Working length, AO grit, filament size, stem, tip, and connection can be customized.
Product Overview
20mm P320 AO 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 20 mm, Brush head length 100 mm, and Handle length 200 mm. This product uses a tube or bore-brush structure for cleaning inside holes, pipes, and narrow passages. The specified interface is threaded removable. Aluminum Oxide Abrasive Nylon 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.

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 20 mm, Brush head length 100 mm, and Handle length 200 mm against the complete working envelope before finalizing the brush.
Contact material
Choose from Aluminum Oxide Abrasive Nylon according to the behavior of chips, oil, and coolant, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. To set the right stiffness, confirm the filament diameter, free trim, and density as well as the material.
When to use another solution
For 20mm P320 AO 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.
