Custom Cleaning Brush
25mm PTFE Chemical Tube Brush
25mm PTFE Chemical 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 cleans chemical-service tubing — The brush is sized for compact internal passages.
PTFE filament provides broad chemical resistance — Suitable for aggressive acids, solvents, and process fluids.
Low-friction bristles release sticky residue more easily — The fill slides over the tube wall without metal contact.
Radial construction cleans the complete inner circumference — Bristles surround the stem.
Corrosion-resistant stem and tip options — PTFE-coated, polymer, or stainless components can be selected.
Working length, PTFE filament size, stem material, tip, and connection can be customized.
Product Overview
25mm PTFE Chemical 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 100 mm, and Handle length 220 mm. This is a tube-style brush design for controlled contact inside internal passages. The specified interface is threaded removable. PTFE Filament 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.

- Match contact to surface risk: Minor
- Use with Acidic Cleaner / Alkaline Cleaner / Organic Solvent
- Confirm interface and clearance before production.
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 100 mm, and Handle length 220 mm against the complete working envelope before finalizing the brush.
Contact material
Choose from PTFE Filament according to the behavior of chips, oil, and coolant, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. Brush stiffness depends on the material plus filament diameter, free trim length, and fill density.
When to use another solution
For 25mm PTFE Chemical 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.
