Weiler 21246 Steel Hand Tube Brush 1/8 Inch Single Spiral

Product Description

The WEILER 21246 is a single-spiral steel hand tube brush designed for cleaning the interior of small-diameter tubes, ports, and passages. The brush head measures 1 inch in length with a 1/8 inch brush diameter, making it suited for tight bores and restricted access points. Steel fill wire at 0.003 inches in diameter provides firm scrubbing action against deposits, scale, and debris without requiring power tools. The galvanized steel shank measures 3/32 inches in diameter and terminates in a loop handle for manual operation. Overall length is 6 inches. This brush is used by HVAC technicians, plumbers, machinists, and maintenance professionals who need precise, hand-controlled tube cleaning.

This brush is suited for cleaning small-bore tubing, orifices, heat exchanger ports, refrigerant line fittings, and similar confined passages found in residential and light commercial HVAC systems, plumbing assemblies, and mechanical equipment. The 6 inch overall length gives enough reach into tube ends while the loop handle allows controlled torque during manual scrubbing. The single spiral fill pattern concentrates bristle contact along the tube wall for consistent cleaning action in straight-bore applications.

Installation Notes

This brush is operated by hand and requires no power tools or chucks. Before cleaning any tube or port on an active system, shut off and isolate the system in accordance with applicable service procedures for the equipment type. Avoid forcing the brush through bends or restrictions smaller than the rated brush diameter, as this can damage bristles and reduce cleaning effectiveness. Dispose of dislodged debris and cleaning media per local shop safety practices.
