The brush head measures 2.5 inches in length with a 0.5625-inch diameter, and the stainless steel wire fill at 0.008-inch filament diameter delivers consistent scrubbing action without shedding or corrosion. The stainless steel shank at 0.142-inch diameter provides a secure, concentric grip in power tools or hand-held pin vises. Overall length is 9 inches, giving the technician adequate reach into deep passages.\u003c\/p\u003e\n\u003cp\u003eThis brush is used across HVAC, plumbing, and general mechanical service work wherever small-diameter passages need to be cleared of scale, flux residue, oxidation, or debris. Common applications include cleaning heat exchanger tubes, pipe fittings, orifice ports, and valve bores. The stainless steel construction makes it suitable for wet or chemically active environments where carbon steel would corrode. It is typically used by HVAC technicians, pipefitters, and maintenance mechanics who require a durable, reusable cleaning tool that fits into confined spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-spiral twist pattern maintains consistent brush density across the 2.5-inch bristle zone\u003c\/li\u003e\n  \u003cli\u003eStainless steel fill wire resists corrosion in wet, oily, or flux-exposed service environments\u003c\/li\u003e\n  \u003cli\u003e0.008-inch wire diameter provides firm scrubbing action without scoring soft alloy surfaces\u003c\/li\u003e\n  \u003cli\u003e0.142-inch stainless steel shank compatible with standard drill chucks and pin vises\u003c\/li\u003e\n  \u003cli\u003e9-inch overall length allows reach into deep bores and tube assemblies\u003c\/li\u003e\n  \u003cli\u003eSingle-piece construction with no adhesive bonding points that could fail under rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose twisted wire bristle brush suitable for bores and passages that accept a 0.5625-inch diameter brush head.

When power-driven, keep rotational speed within the tool and brush manufacturer limits to prevent wire fatigue or shank wobble. Wear appropriate eye protection whenever the brush is rotated, as wire filaments can shed under excessive load or at end of service life. Inspect the bristle zone before each use and replace the brush if wires are bent, kinked, or missing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.008 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.142 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRO-SOURCE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 05078\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51746941731122,"sku":"05078","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb2acae158f2b6a8c30897d4a29a3917.jpg?v=1788874791","url":"https:\/\/voomisupply.com\/products\/pro-source-05078-twisted-wire-bristle-brush-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
