Schaefer Brush 43722 Condenser Tube Brush Nylon

Product Description

The SCHAEFER BRUSH 43722 is a single stem spiral condenser tube brush designed for cleaning condenser tubes in HVAC and refrigeration equipment. The brush features nylon bristles mounted on a spiral stem, providing effective mechanical cleaning of tube inner walls without damaging the tube surface. At 0.75 inches in diameter and 6.25 inches overall length, with a 4-inch brush section, this tool is sized for standard condenser tube bore diameters. The 12-24 female connection allows it to be threaded onto compatible extension rods for deeper tube access. HVAC technicians and refrigeration mechanics keep this brush in regular rotation during condenser cleaning and maintenance services.

The 43722 is suited for residential and light commercial HVAC condenser cleaning applications. It is used to remove scale, debris, and biological buildup from the inner walls of condenser tubes in shell-and-tube heat exchangers and similar equipment. The nylon bristle construction makes it appropriate for use on copper and aluminum tube materials where metal bristles could cause scoring or galvanic concerns. It is commonly deployed during seasonal maintenance, coil cleaning, and system efficiency restoration work.

Installation Notes

A licensed HVAC technician or refrigeration mechanic should de-energize and lock out the system before performing condenser tube cleaning. Ensure refrigerant pressure is relieved and the system is properly isolated before accessing tube sheets or heat exchanger internals. Thread the brush securely onto the extension rod before insertion to prevent disconnection inside the tube. Follow applicable mechanical codes and manufacturer service procedures for the specific equipment being serviced.
