Schaefer Brush 43513 Tube Brush 9/16 in Stainless Steel

Product Description

The SCHAEFER BRUSH 43513 is a double stem, single spiral tube brush designed for cleaning and deburring the interior of tubes, ports, and small-bore passages. The brush measures 9/16 inches in diameter with an overall length of 6-1/4 inches and a brush length of 4 inches. Stainless steel bristles and a stainless steel construction make this brush suitable for use in corrosive environments, high-moisture applications, and situations where bristle contamination must be avoided. The 12-24 female threaded connection allows the brush to attach to standard extension rods or drill shanks. It is a practical hand tool or machine-driven cleaning instrument for HVAC techs, plumbers, and maintenance professionals.

This tube brush is well suited for cleaning copper fittings, tube ends, heat exchanger ports, and small-diameter passages encountered in residential and light commercial HVAC, plumbing, and refrigeration service work. The stainless steel bristle material resists corrosion and maintains bristle stiffness across repeated uses, making it reliable for periodic maintenance routines and one-time installation prep tasks alike. The female threaded connection is compatible with standard brush extension rod systems.

Compatibility

Designed for use with standard 12-24 threaded brush extension rods and handles. Suitable as a tube cleaning brush for small-bore applications in HVAC, plumbing, and refrigeration service where a 9/16 inches diameter brush is required.

Installation Notes

This brush is installed by threading it onto a compatible 12-24 extension rod or handle. When using with a power drill, keep rotational speed low to avoid bristle deformation or thread stripping. Always wear appropriate eye protection when brushing debris from tube interiors. Ensure the tube or fitting being cleaned is depressurized and free of refrigerant, fluid, or gas before brushing.
