Custom Cleaning Brush
25mm PA66 Tube Brush
25mm PA66 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
25 mm head matches common small pipe and tube interiors — The brush cleans the full circumference.
PA66 bristles provide resilient general-purpose scrubbing — Suitable for oil, dust, slime, and loose deposits.
Radial fill reaches around the tube wall — Twisted construction avoids one-sided cleaning.
Rigid, flexible, and threaded stem options — The brush can suit hand or machine use.
Protected end options reduce scratching — Looped or capped tips can be supplied.
Working length, filament stiffness, stem, tip, handle, and connection can be customized.
Product Overview
25mm PA66 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 25 mm, Brush head length 120 mm, and Handle length 220 mm. The design follows a tube and bore-brush format for radial contact on internal surfaces. The specified interface is fixed. PA66 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 25 mm, Brush head length 120 mm, and Handle length 220 mm against the complete working envelope before finalizing the brush.
Contact material
Choose from PA66 Nylon according to the behavior of chips, oil, and coolant, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. Material is only one part of stiffness; filament diameter, exposed length, and density must also be confirmed.
When to use another solution
For 25mm PA66 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.
