Schaefer Brush 93531 Tube Brush 15/16 in Stainless Steel

Product Description

The SCHAEFER BRUSH 93531 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore passages. The brush measures 15/16 inches in diameter with an overall length of 6.25 inches and a brush length of 4 inches. Stainless steel bristles provide corrosion resistance and durability when working in harsh environments or with residue that would degrade softer bristle materials. The male connection end allows the brush to be chucked into a drill or threaded onto a standard extension rod. This tool is used by HVAC technicians, plumbers, and maintenance professionals for bore cleaning and surface prep tasks.

This tube brush is suited for cleaning heat exchanger tubes, condenser tubes, boiler tubes, and similar small-diameter pipe or tubing found in residential and light commercial mechanical systems. The stainless steel construction makes it appropriate for use on stainless, copper, and steel tubing surfaces where a more aggressive clean is needed. The single spiral configuration delivers consistent bristle contact along the full brush length, making it effective for removing scale, flux residue, light oxidation, and debris from tube interiors.

Key Features

• Double stem construction provides rigidity and consistent bristle tension throughout the bore
• Single spiral pattern ensures uniform contact with tube interior walls
• Stainless steel bristles resist corrosion and maintain stiffness under repeated use
• Male connection end is compatible with standard drill chucks and brush extension rods
• Compact 6.25-inch overall length suits tight-access installations

Compatibility

Designed for use in tubes and small-bore pipe applications requiring a 15/16-inch diameter brush. Suitable for HVAC, plumbing, and general maintenance cleaning tasks where stainless steel bristle material is required.

Installation Notes

This brush is installed by HVAC technicians, plumbers, and maintenance trades. Power down and de-energize any associated equipment before inserting the brush into heat exchanger or condenser tubing. When using with a drill, operate at a controlled speed to avoid bristle flare or stem fatigue. Wear appropriate eye protection when power-driving any tube brush.
