It features brass bristles mounted on a double-stem wire construction with a single spiral pattern, providing consistent scrubbing contact along the brush length. The overall length is 6.25 inches with a brush scraping length of 4 inches and a working diameter of 0.875 inches. The male connection end allows the brush to be chucked into a drill or used with a compatible extension. Licensed HVAC technicians, plumbers, and pipe fitters rely on this style of brush for tube prep, scale removal, and bore cleaning during service or installation work.\u003c\/p\u003e\n\u003cp\u003eThis tube brush is suited for use in residential and light commercial applications where internal tube or bore cleaning is required. Typical uses include cleaning copper tube ends before soldering or brazing, removing scale and oxidation from heat exchanger tubes, and deburring or prepping small-diameter pipe bores. The 0.875-inch diameter makes it a direct fit for common tube and pipe sizes encountered in HVAC and plumbing work. The brass bristle construction resists corrosion and is safe for use on soft metals including copper, brass, and aluminum without risk of ferrous contamination.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble stem, single spiral construction maintains bristle shape and scrubbing contact under repeated use\u003c\/li\u003e\n  \u003cli\u003eBrass bristles resist corrosion and are non-ferrous, safe for copper, brass, and aluminum surfaces\u003c\/li\u003e\n  \u003cli\u003e0.875-inch working diameter fits common tube and pipe bore sizes in HVAC and plumbing applications\u003c\/li\u003e\n  \u003cli\u003e4-inch brush length provides thorough coverage of tube interiors in a single pass\u003c\/li\u003e\n  \u003cli\u003eMale connection end compatible with drill chuck or extension rod use\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 6.25 inches allows use in tight or confined spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard OEM-style tube brush for use in 0.875-inch diameter tube and pipe bore cleaning applications typical in HVAC, plumbing, and general maintenance work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is installed and used by licensed HVAC technicians, plumbers, and maintenance professionals. Before cleaning any tube or pipe section, isolate and depressurize the system in accordance with applicable codes including IPC and IFGC guidelines. When using the brush with a powered drill, operate at low speed to avoid deforming the bristle pattern or damaging soft metal tube walls. Inspect the brush before each use and replace if bristles are significantly worn or splayed, as a deformed brush will not maintain proper bore contact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Double Stem Single Spiral Tube Brush\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBristle Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Male\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\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: SCHAEFER BRUSH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 93628\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51543976313138,"sku":"93628","price":22.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/267f613cea85cb0da2e6ef63267f5464.jpg?v=1785922586","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-93628-tube-brush-7-8-in-brass-bristles","provider":"Voomi Supply","version":"1.0","type":"link"}
