Custom Cleaning Brush
6mm PA66 Tube Brush
6mm 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
6 mm brush diameter targets small tubes and ports — The head maintains contact in narrow internal passages.
PA66 bristles provide resilient general-purpose scrubbing — The filament removes oil, dust, and loose residue.
Radial fill cleans around the complete bore — Bristles surround the twisted stem.
Rigid and semi-flexible stem options — The brush can suit straight or gently curved passages.
Looped or capped tip options reduce surface damage — The core can be kept away from the tube wall.
Working length, filament stiffness, stem, tip, handle, and connection can be matched to the tube.
Product Overview
6mm 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 6 mm, Brush head length 60 mm, and Handle length 140 mm. This is a tube-style brush design for controlled contact inside internal passages. The specified interface is fixed. PA66 Nylon are the principal material directions in the current specification. The brush should provide enough reach and control without making the user press the bristles too hard against the surface.

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 6 mm, Brush head length 60 mm, and Handle length 140 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. The same material can feel very different depending on filament diameter, free trim, and fill density.
When to use another solution
For 6mm 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.
