The spiral wire construction keeps stainless steel bristles firmly in place under repeated use, maintaining consistent scrubbing action across the full brush length. At 9\/16 inch in diameter and 6 inches overall length, with a 4-inch brush length, this tool fits into confined passages where larger brushes cannot reach. The 12-24 female threaded connection allows secure attachment to compatible extension rods or handles. Stainless steel bristles and brush construction resist corrosion, making this brush suitable for use with water, mild chemicals, and other fluids common in maintenance and service work.\u003c\/p\u003e\n\u003cp\u003eThis tube brush is suited for maintenance technicians, HVAC service professionals, plumbers, and industrial cleaning personnel who need a reliable small-bore brush for deburring, descaling, or general interior tube cleaning. Typical applications include heat exchanger tubes, condenser tubes, small-diameter pipe fittings, and similar confined bore surfaces. The double stem and spiral design provides firm bristle support, reducing bristle loss during aggressive scrubbing tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble stem spiral construction holds stainless steel bristles securely under repeated use\u003c\/li\u003e\n  \u003cli\u003e9\/16 inch diameter fits small-bore tubes and confined passages\u003c\/li\u003e\n  \u003cli\u003e4-inch brush length with 6-inch overall length for reach into restricted areas\u003c\/li\u003e\n  \u003cli\u003e12-24 female threaded connection for use with standard extension rods\u003c\/li\u003e\n  \u003cli\u003eFull stainless steel bristle and brush material resists corrosion\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 12-24 threaded extension rods and handles.
