Schaefer Brush 14612 Brass Wire Tube Brush 3x7/8 in

Product Description

The SCHAEFER BRUSH 14612 is a long-handle brass wire tube brush designed for cleaning the interior of tubes, pipes, and fittings in HVAC, plumbing, and refrigeration applications. The brush section measures 3 inches in length with a 7/8-inch diameter, and the overall length reaches 15 inches, giving technicians extended reach into confined tubing without additional tooling. Both the fill material and shank are brass, making this brush compatible with copper and other soft-metal tubing where steel bristles could cause scoring. The single-spiral construction delivers consistent scrubbing action along the full bore length. Wire filament diameter is 0.006 inches, providing firm but controlled abrasion suitable for light scale, flux residue, and debris removal.

This tube brush suits residential and light commercial service work where interior tube or bore cleaning is required before soldering, flaring, or fitting installation. HVAC technicians use it to prep copper refrigerant lines and heat exchanger tubes. Plumbers reach for it when cleaning pipe bores prior to sweat connections. The 15-inch overall length and 3/8-inch shank diameter allow it to be chucked into a drill or used by hand, depending on access and surface requirements.

Installation Notes

Shut off and depressurize any line or system before inserting the brush into tubing. Licensed HVAC technicians and plumbers should follow applicable codes when working on refrigerant or potable water systems. When using a drill for powered operation, start at low speed to maintain control and prevent filament flare. Inspect the brush for bent or missing fill wires before each use and replace if the brush diameter or shape is compromised.
