The brush measures 0.75 inches in diameter with an overall length of 6.25 inches, including a 4-inch brush or scraper length. Stainless steel bristles and a stainless steel construction make this brush well suited for applications involving moisture, mild chemicals, or residue buildup that would quickly degrade lesser materials. It connects via a male fitting for use with standard tube brush handles or extensions. Plumbers, HVAC technicians, and industrial maintenance personnel are the primary installers and users.\u003c\/p\u003e\u003cp\u003eThis tube brush sees typical use in residential and commercial plumbing and HVAC service work, where cleaning tube interiors, heat exchanger passages, and bore holes is part of routine maintenance or repair. The 0.75-inch diameter targets smaller tube and pipe bores, and the single spiral configuration provides consistent contact with the tube wall. It is equally at home in light industrial settings for cleaning ports, manifolds, or any bore requiring mechanical scrubbing action.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble stem construction provides added rigidity and support during scrubbing\u003c\/li\u003e\n\u003cli\u003eSingle spiral pattern ensures consistent bristle contact along the full brush length\u003c\/li\u003e\n\u003cli\u003eStainless steel bristles resist corrosion and hold up in wet or mildly chemical environments\u003c\/li\u003e\n\u003cli\u003eMale connection type is compatible with standard tube brush handles and extensions\u003c\/li\u003e\n\u003cli\u003eCompact 6.25-inch overall length allows use in confined access areas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-purpose tube brush for residential and commercial plumbing, HVAC, and industrial maintenance applications requiring a 0.75-inch diameter bore brush with a male connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis brush is installed by hand or attached to a compatible handle or drill extension for power scrubbing. Before cleaning any tube or passage on an active system, shut off fluid flow and relieve system pressure per local plumbing or mechanical codes. Inspect the brush for bent stems or damaged bristles before each use, as deformed brushes can shed wire inside a system. Wear appropriate eye protection when using wire brushes in any orientation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.75 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\u003eBrush Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBristle Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Material\u003c\/strong\u003e: Stainless Steel\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: 0.14 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: 93522\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51543430627634,"sku":"93522","price":21.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4544de489145064919e9cbb2a1cbf75f.jpg?v=1785918530","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-93522-tube-brush-3-4-in-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
