Schaefer Brush 93702 Condenser Tube Brush Nylon

Product Description

The SCHAEFER BRUSH 93702 is a single stem spiral condenser tube brush designed for cleaning the interior of condenser tubes, heat exchanger tubes, and similar small-bore tubing found in HVAC and refrigeration equipment. The brush measures 0.25 inches in diameter with an overall length of 4.5 inches, including a brush length of 3 inches. Nylon bristles are used throughout, making this brush compatible with a wide range of tube materials without risk of scratching or corrosion. The 8-32 male threaded connection allows attachment to standard brush extension rods for reaching deeper into tube assemblies. HVAC technicians and refrigeration service professionals install this brush as part of routine condenser maintenance and tube cleaning procedures.

This condenser tube brush is suited for residential and light commercial HVAC and refrigeration service work where small-diameter tube cleaning is required. The spiral configuration helps dislodge scale, biofilm, and debris from the inner walls of condenser tubes during seasonal maintenance or equipment reconditioning. The 8-32 male threaded end allows the brush to be threaded onto compatible extension rods, enabling technicians to clean tubes that cannot be accessed by hand alone. It is typically used by licensed HVAC technicians and refrigeration mechanics performing coil and heat exchanger service.

Installation Notes

This brush is installed and used by licensed HVAC technicians and refrigeration mechanics during routine maintenance or equipment service. Before cleaning any tube bundle or heat exchanger, shut down and lock out the system per applicable safety procedures.
