The brush head measures 1 inch in length with a 1\/8 inch brush diameter, making it suited for tight bores and restricted access points. Steel fill wire at 0.003 inches in diameter provides firm scrubbing action against deposits, scale, and debris without requiring power tools. The galvanized steel shank measures 3\/32 inches in diameter and terminates in a loop handle for manual operation. Overall length is 6 inches. This brush is used by HVAC technicians, plumbers, machinists, and maintenance professionals who need precise, hand-controlled tube cleaning.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for cleaning small-bore tubing, orifices, heat exchanger ports, refrigerant line fittings, and similar confined passages found in residential and light commercial HVAC systems, plumbing assemblies, and mechanical equipment. The 6 inch overall length gives enough reach into tube ends while the loop handle allows controlled torque during manual scrubbing. The single spiral fill pattern concentrates bristle contact along the tube wall for consistent cleaning action in straight-bore applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch brush length with 1\/8 inch brush diameter for small-bore tube access\u003c\/li\u003e\n  \u003cli\u003eSteel fill wire at 0.003 inches diameter for firm mechanical cleaning action\u003c\/li\u003e\n  \u003cli\u003eSingle spiral construction with one bristle spiral for consistent bore contact\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel shank at 3\/32 inch diameter resists corrosion during wet cleaning tasks\u003c\/li\u003e\n  \u003cli\u003eLoop handle style enables controlled manual rotation without a separate handle tool\u003c\/li\u003e\n  \u003cli\u003e6 inch overall length provides reach into tube ends and fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for manual cleaning of small-diameter tubes, ports, and bores where a 1\/8 inch brush diameter is the appropriate fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is operated by hand and requires no power tools or chucks. Before cleaning any tube or port on an active system, shut off and isolate the system in accordance with applicable service procedures for the equipment type. Avoid forcing the brush through bends or restrictions smaller than the rated brush diameter, as this can damage bristles and reduce cleaning effectiveness. Dispose of dislodged debris and cleaning media per local shop safety practices.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFill Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Material\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Bristle Spirals\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Stem Wires\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Loop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 47131600\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: WEILER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21246\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WEILER","offers":[{"title":"Default Title","offer_id":51544663589170,"sku":"21246","price":15.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0dbe8516ee4054b710cdcc716b0d0e0e_6266dd50-437a-423f-ba32-7fc5e9f72eac.jpg?v=1785932951","url":"https:\/\/voomisupply.com\/products\/weiler-21246-steel-hand-tube-brush-1-8-inch-single-spiral","provider":"Voomi Supply","version":"1.0","type":"link"}
