The brush measures 15\/16 inches in diameter with an overall length of 6.25 inches and a brush length of 4 inches. Stainless steel bristles provide corrosion resistance and durability when working in harsh environments or with residue that would degrade softer bristle materials. The male connection end allows the brush to be chucked into a drill or threaded onto a standard extension rod. This tool is used by HVAC technicians, plumbers, and maintenance professionals for bore cleaning and surface prep tasks.\u003c\/p\u003e\u003cp\u003eThis tube brush is suited for cleaning heat exchanger tubes, condenser tubes, boiler tubes, and similar small-diameter pipe or tubing found in residential and light commercial mechanical systems. The stainless steel construction makes it appropriate for use on stainless, copper, and steel tubing surfaces where a more aggressive clean is needed. The single spiral configuration delivers consistent bristle contact along the full brush length, making it effective for removing scale, flux residue, light oxidation, and debris from tube interiors.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble stem construction provides rigidity and consistent bristle tension throughout the bore\u003c\/li\u003e\n\u003cli\u003eSingle spiral pattern ensures uniform contact with tube interior walls\u003c\/li\u003e\n\u003cli\u003eStainless steel bristles resist corrosion and maintain stiffness under repeated use\u003c\/li\u003e\n\u003cli\u003eMale connection end is compatible with standard drill chucks and brush extension rods\u003c\/li\u003e\n\u003cli\u003eCompact 6.25-inch overall length suits tight-access installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in tubes and small-bore pipe applications requiring a 15\/16-inch diameter brush.
