It features stainless steel bristles mounted on a stainless steel brush body, making it suitable for applications where corrosion resistance and durability are required. The brush measures 9\/16 inch in diameter with an overall length of 6-1\/4 inches and a brush length of 4 inches. The male connection end allows the brush to be chucked into a drill or attached to an extension rod for deeper access. It is commonly used by HVAC technicians, plumbers, and maintenance professionals for tube and pipe cleaning tasks.\u003c\/p\u003e\u003cp\u003eThis tube brush is well suited for cleaning heat exchanger tubes, condenser tubes, boiler tubes, and similar cylindrical bore applications in both residential and light commercial settings. The stainless steel construction holds up against rust and chemical exposure, making it a practical choice for wet or corrosive environments.
