The brush measures 3.25 inches in diameter with a 7.5-inch overall length and a 4.5-inch brush length. Tempered steel wire construction provides aggressive scrubbing action against soot, scale, and carbon deposits. The 1\/4-inch male NPSM connection allows the brush to be threaded onto standard extension rods, making it a practical hand tool for HVAC technicians and chimney service professionals performing routine flue maintenance.\u003c\/p\u003e\n\u003cp\u003eThis flue brush is suited for residential and light commercial service work where flue passages, B-vent connectors, or heat exchanger tubes require periodic cleaning.
