The brush features a 3\/4 inch inside diameter with a 15\/16 inch actual brush diameter, allowing it to scrub the interior walls of fittings, ports, and tubing with consistent contact. The stainless steel bristles resist corrosion and stand up to repeated use in wet or oily service environments. Overall length is 3-5\/8 inches with a 3\/16 inch shank diameter, making it compatible with standard power drills and flex-shaft tools used in field service work. HVAC technicians and refrigeration mechanics rely on this style of brush to prepare fittings before brazing or to remove debris from tube bores.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for use in residential and light commercial refrigeration systems, HVAC equipment, and anywhere that tube or fitting interiors need to be cleaned before assembly or repair. The 7\/8 inch refrigeration outside diameter spec aligns it with common ACR tubing and fitting sizes found in split systems, condensing units, and refrigeration circuits. The stainless steel construction makes it appropriate for use with refrigerant-grade fittings where contamination from carbon steel must be avoided.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel bristles resist corrosion and contamination in refrigeration service\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch inside diameter and 15\/16 inch actual brush diameter for consistent fitting contact\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch refrigeration outside diameter sizing fits standard ACR tubing and fittings\u003c\/li\u003e\n  \u003cli\u003eTwisted wire stem construction holds bristle shape under power tool use\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch shank diameter fits standard drill chucks and flex-shaft drivers\u003c\/li\u003e\n  \u003cli\u003eCompact 3-5\/8 inch overall length suits tight access in equipment panels and line sets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and service brush for refrigeration and HVAC fitting cleaning applications where a 3\/4 inch inside diameter, stainless steel twisted wire brush with a 3\/16 inch shank is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this brush requires no special trade licensing, but it is typically used by licensed HVAC technicians and refrigeration mechanics during system service or repair. Secure the 3\/16 inch shank firmly in the drill chuck before operation to prevent ejection. Always power down and de-energize the equipment being serviced before accessing fittings or tube connections. Inspect bristle condition before each use and replace the brush if the wire stem or bristles show signs of deformation or fatigue.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Brush Diameter\u003c\/strong\u003e: 0.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigeration Outside Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Type\u003c\/strong\u003e: Twisted Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: SCHAEFER BRUSH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 08748-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51538970607922,"sku":"08748-12","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a158124fb884dc5c8c8174f3ccfdecb6.jpg?v=1785831352","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-08748-12-power-fitting-cleaning-brush","provider":"Voomi Supply","version":"1.0","type":"link"}
