Schaefer Brush 43484 Spiral Tube Brush 3/4 in 6-1/4 in Oal

Product Description

The SCHAEFER BRUSH 43484 is a single stem spiral tube brush designed for cleaning the interior walls of tubes, pipes, and bores in maintenance and service applications. The brush head is constructed from silicone carbide impregnated nylon bristles, which provide abrasive scrubbing action suitable for removing deposits, scale, and debris from interior surfaces without the corrosion concerns associated with wire brushes. The overall length is 6-1/4 inches with a brush working length of 4 inches and a 3/4-inch brush diameter. A 12-24 female threaded connection allows attachment to compatible extension rods or handles for reach into confined passages.

This tube brush is suited for HVAC, plumbing, and general industrial maintenance tasks where internal bore cleaning is required. Typical applications include cleaning heat exchanger tubes, condenser tubes, drain lines, and small-diameter pipe sections. The silicone carbide impregnated nylon construction makes it appropriate for use on metal, plastic, and coated tube interiors where wire bristles could cause surface damage. It is sold individually and is handled by service technicians, maintenance mechanics, and facilities personnel as part of routine cleaning operations.

Compatibility

Designed for use with threaded extension rods and handles featuring a 12-24 male thread. Suitable as a replacement or supplemental brush for tube and bore cleaning setups requiring a 3/4-inch diameter spiral brush with a female 12-24 connection.

Installation Notes

A licensed or qualified service technician should ensure the system or equipment being cleaned is fully de-energized and depressurized before inserting any brush into internal passages. Thread the 12-24 female connection securely onto a compatible male-threaded rod or handle before use to prevent separation during cleaning strokes. Inspect bristle condition before each use and replace the brush if bristles are worn, splayed, or missing, as degraded bristles reduce cleaning effectiveness and may leave debris in the bore.
