Schaefer Brush 43719 Condenser Tube Brush 11/16 in Nylon

Product Description

The SCHAEFER BRUSH 43719 is a single stem spiral condenser tube brush designed to clean the interior walls of condenser tubes in HVAC and refrigeration equipment. With a 11/16 inch brush diameter and a 6-1/4 inch overall length, it reaches into standard condenser tube bores to remove scale, biofilm, and debris that restrict heat transfer. The brush body and bristles are constructed from nylon, making it resistant to corrosion and compatible with wet cleaning environments. The 12-24 female threaded connection allows it to attach to standard extension rods for deeper reach into tube sheets. HVAC technicians and refrigeration service pros use this brush during routine condenser maintenance and coil cleaning procedures.

This brush is suited for residential and light commercial HVAC systems, chiller tube bundles, and heat exchanger condenser tubes where interior tube cleaning is required. The spiral stem design works the nylon bristles against tube walls as the brush is advanced and rotated, dislodging fouling without scratching copper or steel tube interiors. It is appropriate for use during seasonal maintenance, system recommissioning, or troubleshooting reduced system efficiency caused by tube fouling.

Compatibility

Designed for use in condenser tubes accepting an 11/16 inch diameter brush with a 12-24 female threaded connection. Suitable for copper, steel, and coated tube interiors commonly found in residential and commercial HVAC condenser and heat exchanger assemblies.

Installation Notes

HVAC technicians and refrigeration mechanics should disconnect and lock out power to the system before accessing tube sheets or condenser bundles. Thread the brush onto a compatible 12-24 male extension rod before inserting into the tube bore. Advance and rotate the brush with steady, even strokes to avoid bending the stem. Follow applicable safety and environmental guidelines for collection and disposal of dislodged debris and cleaning fluids.
