Weiler 21104 Stainless Steel Hand Tube Brush 2x0.5in

Product Description

The WEILER 21104 is a single-spiral hand tube brush designed for cleaning the interior surfaces of tubes, pipes, and small-bore fittings. The brush head measures 2 inches long with a 1/2 inch diameter, and the overall assembly extends 8 inches in length, giving technicians adequate reach into confined passages. Bristles are stainless steel wire at 0.004 inches in diameter, providing durable scrubbing action without shedding material that could contaminate a system. The 1/8 inch galvanized steel shank and loop handle make it easy to work by hand in tight service areas without additional tooling.

This tube brush is suited for HVAC, plumbing, and refrigeration service work where tube and fitting bores need to be cleaned before brazing, flaring, or reassembly. It is also used in light industrial maintenance to clear scale, debris, or oxidation from small-diameter tubing. The compact brush head fits standard tube sizes commonly encountered in residential and light commercial installations. Trade professionals including HVAC technicians, plumbers, and pipefitters will find this brush useful during routine service calls and installation prep.
