Schaefer Brush 43731 Condenser Tube Brush 15/16 in

Product Description

The SCHAEFER BRUSH 43731 is a single stem spiral condenser tube brush designed for cleaning the interior walls of condenser tubes in HVAC and refrigeration equipment. The brush features a nylon bristle construction on a spiral stem, delivering effective mechanical scrubbing action to remove scale, biofilm, and debris buildup from tube surfaces. It measures 15/16 inch in diameter and 6-1/4 inches overall length, with a 4-inch brush section and a 12-24 female threaded connection for use with standard extension rods. HVAC technicians and refrigeration service pros reach for this brush during routine condenser tube maintenance to restore heat-transfer efficiency.

This brush is suited for residential and light commercial HVAC applications where condenser tubes require periodic mechanical cleaning. The 15/16 inch diameter fits standard condenser tube bore sizes commonly found in shell-and-tube heat exchangers and condenser assemblies. The 12-24 female threaded connection allows the brush to be threaded onto compatible extension rods for reaching deeper tube passes. It is sold individually and is appropriate for use during scheduled preventive maintenance or corrective cleaning service calls.

Installation Notes

Installation and use of this brush should be performed by a qualified HVAC or refrigeration technician. Before cleaning condenser tubes, shut down the associated system and relieve any system pressure per standard lockout/tagout procedures. Thread the brush onto a compatible 12-24 extension rod and insert it into the tube bore with steady, controlled strokes. Avoid forcing the brush into tubes that are significantly undersized, as this can damage bristles or deform tube walls.
