The brush features a 1 inch diameter and a 6.25 inch overall length, with a 4 inch brush scraper length that delivers consistent contact along the working surface. Brass bristles provide effective scrubbing without the risk of scratching softer metal surfaces. The 12-24 female threaded connection allows the brush to be attached to compatible extension rods for deeper reach into tubes or heat exchanger passages. This brush is suited for use by HVAC technicians, plumbers, and maintenance professionals.\u003c\/p\u003e\u003cp\u003eThis tube brush is used in applications that require internal bore cleaning, including heat exchanger tubes, condenser tubes, copper pipe fittings, and similar cylindrical passages. The brass bristle construction makes it appropriate for use on copper, brass, aluminum, and other non-ferrous surfaces where steel bristles would be too aggressive. It is well suited for both shop bench work and field service tasks in residential and light commercial HVAC and plumbing applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch brush diameter for cleaning standard tube and pipe bores\u003c\/li\u003e\n\u003cli\u003e4 inch brush scraper length for thorough internal surface contact\u003c\/li\u003e\n\u003cli\u003eBrass bristles safe for use on copper, brass, and aluminum surfaces\u003c\/li\u003e\n\u003cli\u003eDouble stem, single spiral construction for firm bristle retention and consistent shape\u003c\/li\u003e\n\u003cli\u003e12-24 female threaded connection compatible with standard extension rod systems\u003c\/li\u003e\n\u003cli\u003eCompact 6.25 inch overall length suitable for both bench and field use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 12-24 threaded extension rods and handles.

Thread the brush securely onto any compatible 12-24 extension rod before use to prevent separation inside the tube. Use appropriate personal protective equipment when cleaning heat exchanger or condenser tubes that may contain chemical residues or scale buildup. Inspect bristle condition before each use and replace the brush if bristles are bent, compressed, or significantly worn.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush\/Scraper Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBristle Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush\/Scraper Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Female threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 12-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCHAEFER BRUSH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 43633\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51538836259122,"sku":"43633","price":19.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7191e3f00005b9ba66c9fcbe3d893956.jpg?v=1785827976","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-43633-tube-brush-1-in-brass-bristles","provider":"Voomi Supply","version":"1.0","type":"link"}
