The brush head measures 0.5625 inches in diameter and 2.5 inches in length, with a 9-inch overall length that provides reach into confined passages. Steel fill wire at 0.005 inches in diameter delivers firm mechanical scrubbing action to remove scale, debris, and fouling from metal tube walls. The galvanized steel shank at 0.15625 inches in diameter terminates in a loop handle for hand operation without a drill or power tool. Plumbers, HVAC technicians, and pipefitters use this brush for prep work and maintenance tasks on tubing and small-bore components.\u003c\/p\u003e\u003cp\u003eThis brush is suited for residential and light commercial maintenance applications where hand-cleaning of tube interiors is required. Typical use cases include cleaning copper sweat fittings before soldering, deburring and clearing heat exchanger tubes, and removing oxidation or residue from small-bore pipe ends. The single-spiral configuration provides consistent contact around the tube interior wall. The loop handle allows controlled hand torque without the need for a power driver.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-spiral steel fill wire for consistent interior tube contact\u003c\/li\u003e\n\u003cli\u003e0.005-inch wire diameter provides firm scrubbing without aggressive material removal\u003c\/li\u003e\n\u003cli\u003e9-inch overall length for reach into deeper passages\u003c\/li\u003e\n\u003cli\u003eGalvanized steel shank resists corrosion in wet service environments\u003c\/li\u003e\n\u003cli\u003eLoop handle design for hand-operated use without power tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for hand-cleaning of tubes and small-bore fittings with an interior diameter compatible with a 0.5625-inch brush head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eShut off and depressurize any line or fitting before inserting the brush. Insert the brush with steady axial rotation using the loop handle — do not force the brush into a bore smaller than the rated brush diameter. Inspect fill wire condition before each use and retire the brush if wires are kinked, broken, or missing. No power tool is required or recommended for this loop-handle brush.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.15625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Material\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Bristle Spirals\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Stem Wires\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Loop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: WEILER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21233\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEILER","offers":[{"title":"Default Title","offer_id":51540934885682,"sku":"21233","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1fcc404c979c1eac11fa6ae5eb0912ed.jpg?v=1785866084","url":"https:\/\/voomisupply.com\/products\/weiler-21233-steel-hand-tube-brush-9-16-in-single-spiral","provider":"Voomi Supply","version":"1.0","type":"link"}
