Built with stainless steel bristles and a stainless steel brush body, this brush delivers corrosion-resistant performance in wet, chemical, or industrial environments. The brush measures 7\/8 inch in diameter with an overall length of 6-1\/4 inches and a brush scrubbing length of 4 inches. The 12-24 female threaded connection allows attachment to compatible extension handles or drill adapters. Maintenance technicians, plumbers, and HVAC service pros use this brush for tube cleaning during routine servicing and equipment maintenance.\u003c\/p\u003e\n\u003cp\u003eThis tube brush is suited for light industrial, mechanical, and trade service applications. It is commonly used to clean heat exchanger tubes, condenser tubes, boiler tubes, and similar cylindrical passages where debris, scale, or fouling must be removed. The stainless steel construction makes it appropriate for use in environments exposed to moisture, mild acids, or caustic cleaning solutions where carbon steel bristles would corrode prematurely. It is sold individually and requires no special tooling beyond a compatible threaded handle or drill chuck adapter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel bristles and brush body for corrosion-resistant cleaning in wet or chemical environments\u003c\/li\u003e\n  \u003cli\u003eDouble stem, single spiral construction provides consistent radial bristle pressure across the tube bore\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch brush diameter sized for standard tube and bore cleaning applications\u003c\/li\u003e\n  \u003cli\u003e4 inch brush scrubbing length provides effective contact area within the tube\u003c\/li\u003e\n  \u003cli\u003e12-24 female threaded connection for use with compatible extension handles or power drive adapters\u003c\/li\u003e\n  \u003cli\u003eCompact 6-1\/4 inch overall length allows use in confined or restricted access locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 12-24 threaded extension handles and drive adapters.
