Schaefer Brush 42602 Nylon Tube Brush 4.5x1 Inch Single Spiral

Product Description

The SCHAEFER BRUSH 42602 is a single-spiral nylon tube brush designed for cleaning and deburring the interior of tubes, pipes, and fittings. The brush measures 4.5 inches in working length with a 1-inch brush diameter and a 7-inch overall length. Nylon fill material with a 0.018-inch filament diameter provides effective scrubbing action while resisting corrosion and chemical exposure. The 0.25-inch stainless steel shank mounts securely to a drill or flexible drive for powered or hand operation. HVAC, plumbing, and refrigeration technicians commonly use this style of brush to clean coil headers, condenser tubes, and copper fittings before brazing or soldering.

This tube brush suits residential and light commercial service applications where tube or pipe interior cleaning is required prior to connection, repair, or inspection. It is well matched for use on copper, PVC, and similar tubing found in HVAC refrigerant lines, hydronic systems, and plumbing rough-in work. The 1-inch brush diameter and 7-inch overall length allow access into tight or recessed tube ends without the need for an extension.

Installation Notes

Tube brushes of this type are installed by HVAC technicians, plumbers, and pipefitters using a hand drill or flexible drive. Ensure the work area is de-energized and refrigerant or water systems are depressurized before cleaning tube interiors. Insert the shank into a standard drill chuck and run at low to moderate speed to avoid filament wear. Follow applicable codes such as the IFGC or IPC for any pipe preparation steps required before joining.
