It features a 0.25-inch inside diameter bore, a 0.4375-inch actual brush diameter, and a 0.25-inch shank diameter with a hex shaft stem for use in a power drill or driver. The overall length is 3.125 inches. Stainless steel fill wire resists corrosion and holds up against refrigeration oils and residues. HVAC and refrigeration technicians rely on this type of brush to clean fitting seats before brazing or flaring operations.\u003c\/p\u003e\u003cp\u003eThis brush is suited for residential and light commercial HVAC and refrigeration service work. The hex shaft stem allows it to be chucked into a standard drill, making fitting preparation faster compared to hand brushing. The 0.375-inch refrigeration outside diameter corresponds to common copper tubing and fitting sizes encountered in refrigeration line work. It is typically used during line set installation, repair, or system retrofits where clean, oxide-free surfaces are required for leak-free joints.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel bristles resist corrosion and hold up to refrigeration oils and flux residues\u003c\/li\u003e\n\u003cli\u003eHex shaft stem accepts standard drill chucks for power-driven operation\u003c\/li\u003e\n\u003cli\u003e0.25-inch inside diameter fits common small-bore refrigeration fittings\u003c\/li\u003e\n\u003cli\u003e0.4375-inch actual brush diameter provides consistent contact across the fitting surface\u003c\/li\u003e\n\u003cli\u003e3.125-inch overall length gives clearance for most hand drill and right-angle applications\u003c\/li\u003e\n\u003cli\u003eSold individually — no minimum quantity beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on 0.375-inch outside diameter refrigeration fittings and tubing connections typical in small-bore HVAC and refrigeration applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHVAC and refrigeration technicians install and use this brush as part of fitting preparation before brazing or flaring. Always depressurize and isolate the refrigerant circuit before working on any fittings or tubing. Chuck the hex shaft securely into a variable-speed drill and run at moderate speed to avoid flaring the bristles or damaging soft copper fitting surfaces. Wear appropriate eye protection when operating any rotary wire brush tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActual Brush Diameter\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefrigeration Outside Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Type\u003c\/strong\u003e: Hex Shaft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrush Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 09744-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51543970218290,"sku":"09744-12","price":26.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0368cd286f81907a6d58f8d2d868f84e.jpg?v=1785922554","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-09744-12-power-fitting-cleaning-brush","provider":"Voomi Supply","version":"1.0","type":"link"}
