Schaefer Brush 42606 Nylon Tube Brush 2 in Single Spiral

Product Description

The SCHAEFER BRUSH 42606 is a single-spiral nylon tube brush designed for cleaning and deburring the interior of tubes, pipes, and cylindrical passages. The brush measures 2 inches in diameter and 4.5 inches in brush length, with a 7-inch overall length that provides reach into confined passages. A 0.25-inch stainless steel shank mounts directly to a drill or flex-shaft driver. The nylon fill material with a 0.022-inch filament diameter offers chemical resistance and moderate abrasion for clearing debris, scale, and residue from tube interiors without scratching softer base materials. HVAC technicians, plumbers, and refrigeration mechanics use this brush for routine tube maintenance and inspection prep.

This tube brush is suited for residential and light commercial applications where tube or pipe interior cleaning is required. Common uses include cleaning heat exchanger tubes, copper refrigerant line ends, condensate drain line fittings, and plumbing pipe bores prior to soldering or fitting installation. The 2-inch diameter and 7-inch overall length make it practical for standard trade tubing sizes encountered in HVAC and plumbing service work.

Compatibility

Designed as an OEM-style replacement and general-service tube brush suited for cleaning 2-inch nominal diameter tube and pipe interiors in HVAC, refrigeration, and plumbing applications.

Installation Notes

This brush is installed by a technician or mechanic using a hand drill, cordless driver, or flex-shaft tool fitted with a standard chuck accepting a 0.25-inch shank. Before brushing any tube that is part of an active system, shut down the equipment and isolate or depressurize the line per applicable IFGC, IPC, or NEC requirements for the system type. Operate at low to moderate drill speed to avoid filament distortion or premature wear. Inspect filaments before each use and replace the brush if fill material shows significant deformation or loss.
