Custom Cleaning Brush
38mm PA612 Boiler Tube Brush
38mm PA612 Boiler 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
38 mm head targets boiler and process tubes — The brush maintains circumferential contact.
PA612 bristles provide resilient wet cleaning with lower moisture uptake than common nylon — Stiffness stays more consistent.
Polymer fill removes soot, dust, and light deposits without metal wire contamination — Suitable for routine maintenance.
Radial bristles clean the complete internal wall — The head works around the bore.
Threaded rod connections support deep access — Extension systems can reach long tubes.
Working length, PA612 filament, stem, thread, tip, and rod system can be customized.
Product Overview
38mm PA612 Boiler 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 38 mm, Brush head length 150 mm, and Handle length 300 mm. The design follows a tube and bore-brush format for radial contact on internal surfaces. The specified interface is threaded removable. PA612 Nylon are the principal material directions in the current specification. The stroke, guide clearance, and flexible length must be checked against the complete movement envelope.

Selection Guidance
Structure fit
Match the tube & pipe bore brush geometry to internal walls, threads, and blind holes, the available access, and reciprocating motion. Confirm Brush head diameter 38 mm, Brush head length 150 mm, and Handle length 300 mm against the complete working envelope before finalizing the brush.
Contact material
Choose from PA612 Nylon according to the behavior of chips, oil, and coolant, 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 38mm PA612 Boiler 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.
