Schaefer Brush 93704 Condenser Tube Brush 3/8 in Nylon

Product Description

The SCHAEFER BRUSH 93704 is a single stem spiral condenser tube brush designed for cleaning the interior of condenser tubes in HVAC and refrigeration systems. The brush measures 3/8 inch in diameter with a 6-1/4 inch overall length and a 4-inch brush length. Nylon bristles provide effective scrubbing action to remove deposits, scale, and debris from tube walls without damaging soft copper or aluminum tubing. The 8-32 male threaded connection allows the brush to attach to standard extension rods for deeper tube access. HVAC technicians and refrigeration mechanics use this tool during routine condenser maintenance and coil cleaning service calls.

This condenser tube brush is suited for residential and light commercial HVAC and refrigeration equipment where tube-and-shell or tube-type condenser coils require periodic mechanical cleaning. It is particularly useful during seasonal maintenance, equipment reconditioning, and efficiency restoration work where fouled condenser tubes are reducing heat transfer. The nylon bristle construction makes it appropriate for use on softer tube materials where wire bristles could cause abrasion or scoring.

Key Features

• 3/8 inch brush diameter fits standard condenser tube bore sizes
• Nylon bristles resist corrosion and are safe for use on copper and aluminum tubing
• 4-inch brush length provides thorough coverage per stroke
• 6-1/4 inch overall length with 8-32 male threaded connection for use with extension rods
• Spiral stem construction maintains bristle contact with tube walls during rotation

Compatibility

Designed as a standard OEM-style condenser tube cleaning brush for use in HVAC and refrigeration systems with tube bores compatible with a 3/8 inch brush diameter.

Installation Notes

This brush is used by HVAC technicians and refrigeration mechanics during condenser maintenance. Shut down and de-energize the equipment before accessing condenser tubes for cleaning. Attach the brush to a compatible extension rod using the 8-32 male threaded connection, and use steady in-and-out strokes to clear tube deposits. Flush tubes with water or an approved coil cleaner after brushing to remove loosened debris.
