It measures 1-1\/4 inches in diameter with a 7-1\/4 inch overall length and a 5-inch brush length. The bristles and brush body are both constructed from nylon, making this brush suitable for applications where abrasion on softer metal or plastic surfaces is a concern. A 1\/4-inch NPSM male connection allows the brush to attach to a handle or extension. HVAC technicians, plumbers, and maintenance professionals use this style of brush for tube cleaning, heat exchanger maintenance, and general pipe bore prep work.\u003c\/p\u003e\n\u003cp\u003eThis tube brush is suited for light-duty cleaning in residential and commercial service environments. Typical applications include cleaning copper tube ends before fitting, clearing debris from small-bore pipe sections, and scrubbing the interior of condenser or evaporator tubes during scheduled maintenance. The nylon bristle construction resists common cleaning solvents and mild acids, making it a practical choice for wet or chemically assisted cleaning tasks in plumbing and HVAC service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4 inch brush diameter for small-bore tube and pipe cleaning\u003c\/li\u003e\n  \u003cli\u003e7-1\/4 inch overall length with a 5-inch brush section\u003c\/li\u003e\n  \u003cli\u003eNylon bristles and nylon brush body resist moisture and mild chemicals\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPSM male connection for use with standard handles or extensions\u003c\/li\u003e\n  \u003cli\u003eSingle stem spiral construction maintains consistent contact along the tube wall\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style tube brush for use in residential and commercial plumbing and HVAC service applications requiring a 1-1\/4 inch bore cleaning tool with a 1\/4-inch NPSM male threaded connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is installed by threading the 1\/4-inch NPSM male connection onto a compatible handle or extension rod.
