Schaefer Brush 93713 Condenser Tube Brush 9/16 in Nylon

Product Description

The SCHAEFER BRUSH 93713 is a single stem spiral condenser tube brush designed for cleaning the interior of condenser tubes, heat exchangers, and similar cylindrical passages in HVAC and refrigeration equipment. Built with nylon bristles, it removes scale, biofilm, and debris from tube walls without abrading softer metals. The brush measures 9/16 inch in diameter and 6.25 inches overall, with a brush and scraper length of 4 inches. The male connection end allows it to attach to standard extension rods for deeper reach. HVAC technicians and refrigeration mechanics reach for this tool during routine condenser maintenance and system clean-outs.

This brush is suited for residential and light commercial HVAC applications where condenser tube cleaning is part of scheduled preventive maintenance or system restoration. It fits tubes sized for a 9/16 inch brush diameter, making it appropriate for smaller-bore condenser and chiller tube bundles. The nylon bristle construction is compatible with copper, aluminum, and other non-ferrous tube materials commonly found in split-system and packaged cooling equipment.

Key Features

Compatibility

Designed as an OEM-style cleaning accessory for condenser tubes and heat exchanger tube bundles requiring a 9/16 inch diameter brush.

Installation Notes

Condenser tube brushes are typically used by HVAC technicians and refrigeration mechanics during planned maintenance or corrective service. Before brushing, shut down and lock out the unit per OSHA lockout/tagout procedures and relieve any system pressure where applicable. Insert the brush into the tube with steady, even strokes and avoid forcing an oversized brush into an undersized tube, as this can damage tube walls. Pair with appropriate extension rods when tube depth exceeds the brush overall length.
