Schaefer Brush 43536 Spiral Tube Brush 1-1/4 in Stainless Steel

Product Description

The SCHAEFER BRUSH 43536 is a double stem, double/single spiral tube brush designed for cleaning the interior of tubes, pipes, and bore passages. The brush features stainless steel bristles and a stainless steel brush body, making it suitable for use in wet, corrosive, or high-residue environments where carbon steel would degrade. At 1-1/4 inches in diameter and 7-1/4 inches overall length with a 4-1/2 inch brush section, this tool is sized for standard tube and pipe cleaning tasks. It connects via a 1/4 inch NPSM male fitting, allowing it to mount to standard brush extension rods or cleaning handles. HVAC technicians, plumbers, and maintenance professionals use this brush for routine tube cleaning and maintenance procedures.

This tube brush is suited for cleaning heat exchanger tubes, condenser tubes, evaporator coils, pipe bores, and similar cylindrical passages found in residential and commercial HVAC, refrigeration, and plumbing systems. The double stem spiral construction holds bristle fill securely and maintains brush shape through repeated passes. The 1/4 inch NPSM male connection makes it compatible with standard brush rod extensions used in most tube cleaning setups. It is sold individually.

Installation Notes

Installation and use of this brush is typically performed by licensed HVAC technicians, plumbers, or trained maintenance personnel. Always shut down and lock out the associated equipment before inserting any brush or cleaning tool into tubes or pipe passages. Attach the brush securely to an appropriate extension rod rated for the connection size before use. Avoid forcing the brush through passages significantly smaller than the rated brush diameter, as this can damage bristles and reduce cleaning effectiveness.
