Wide horsehair bristles hold flux evenly and release it with controlled coverage onto fittings, joints, and copper tubing. The compact handle and narrow head allow precise application in tight spaces such as valve assemblies, compression fittings, and sweat connections. This brush is a standard consumable on any plumber or HVAC technician's bench and ships in a boxed pack of 144 units, making it practical for shop stocking or field kits.\u003c\/p\u003e\n\u003cp\u003eThis acid brush is suited for residential and commercial plumbing installations, HVAC refrigerant line brazing prep, and general soldering tasks where flux must be applied before heat is introduced. The 3\/8-inch bristle width is a widely used size for standard copper tube fittings ranging from small-diameter domestic water lines up to moderate HVAC line sets. Plumbers, pipefitters, and HVAC technicians use this brush during sweat-soldering and brazing operations as part of standard joint preparation workflow.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-inch bristle width suited for standard copper fittings and tube ends\u003c\/li\u003e\n  \u003cli\u003eWide horsehair bristles provide even flux distribution and good fluid retention\u003c\/li\u003e\n  \u003cli\u003eCompatible with both liquid and paste soldering flux formulations\u003c\/li\u003e\n  \u003cli\u003eCompact head allows access in confined joint areas and tight valve spaces\u003c\/li\u003e\n  \u003cli\u003eBoxed pack of 144 units supports bulk stocking for shops and service fleets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with liquid or paste soldering flux in standard copper tube soldering and brazing applications common to plumbing and HVAC service work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAcid brushes are a single-use or limited-use consumable handled by licensed plumbers and HVAC technicians during joint preparation. Always shut off the water supply or system pressure and allow components to cool before applying flux and introducing heat. Flux should be applied sparingly and only to the surfaces being joined, in accordance with the flux manufacturer directions and applicable plumbing codes such as the IPC. Dispose of used brushes after soldering to avoid cross-contaminating flux containers.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBristle Width\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBristle Material\u003c\/strong\u003e: Horsehair\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Flux Types\u003c\/strong\u003e: Liquid and paste soldering flux\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 144 units\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.5 pounds (full pack)\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: Forney Industries\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 38140\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FORNEY","offers":[{"title":"Default Title","offer_id":51562096820530,"sku":"38140","price":126.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a36b29ef17e13177e4884cad5cbfaf2.jpg?v=1786471454","url":"https:\/\/voomisupply.com\/products\/forney-industries-38140-acid-brush-3-8-inch-144-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
