Schaefer Brush 14652 Brass Wire Tube Brush 3x7/8 in

Product Description

The SCHAEFER BRUSH 14652 is a single-spiral brass wire tube brush built for cleaning the interior of tubes, ports, and fittings where a standard brush cannot reach. The brush head measures 3 inches long with a 7/8-inch diameter, and the overall assembly extends 27 inches to give technicians the reach needed to service deep passages without obstruction. Fill material and shank are both brass, making this brush compatible with work on softer metals and surfaces where steel bristles would cause damage. Wire diameter of 0.006 inches provides firm yet controlled scrubbing action. Plumbers, HVAC technicians, and refrigeration service pros typically reach for this tool when clearing scale, flux residue, or debris from tube interiors.

This brush suits residential and light commercial service applications where access to tube bores, heat exchanger ports, coil passages, or similar confined channels is required. The 27-inch overall length makes it practical for reaching deeply recessed fittings or cleaning through assembled components without full disassembly. The 3/8-inch shank diameter allows use with compatible drill chucks or hand holders for powered or manual operation.

Compatibility

Installation Notes

No power shutdown is required for brush-only cleaning tasks, but all system pressure should be relieved and fluid isolated before inserting any brush into active plumbing or refrigerant lines. When using with a power drill, select a low speed setting to avoid distorting the spiral or bending the shank. Inspect the brush before each use for splayed or broken wires that could dislodge inside a tube. Follow all applicable safety protocols for the system being serviced.
