The brush features brass bristles mounted on a double-stem wire construction, giving it the lateral stiffness needed to scrub residue, scale, and debris from bore walls without collapsing under pressure. With a 15\/16 inch diameter and an overall length of 6.25 inches, including a 4-inch brush length, it fits a specific range of tube sizes. The male connection end allows it to be chucked into a drill or used with compatible extension handles. Installed by plumbers, HVAC technicians, and maintenance trades.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for cleaning copper tubing, heat exchanger tubes, condenser tubes, and similar cylindrical passages where bore integrity and surface cleanliness are critical before brazing, soldering, or inspection. The brass bristle material is non-sparking and will not score softer tube materials such as copper or aluminum. It is a practical choice for service and maintenance work in residential and light commercial settings where tube cleanliness directly affects joint quality or heat transfer efficiency.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble stem construction provides lateral rigidity for effective bore scrubbing\u003c\/li\u003e\n  \u003cli\u003eSingle spiral bristle pattern ensures consistent contact along the tube wall\u003c\/li\u003e\n  \u003cli\u003eBrass bristles are non-sparking and safe for use on copper and aluminum tubing\u003c\/li\u003e\n  \u003cli\u003e15\/16 inch diameter fits a specific tube bore size without improvised sizing\u003c\/li\u003e\n  \u003cli\u003eMale connection end is compatible with standard drill chucks and extension rods\u003c\/li\u003e\n  \u003cli\u003e4-inch brush length covers typical tube cleaning depths in one pass\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit tube brush for cleaning 15\/16 inch diameter tube bores in plumbing, HVAC, and industrial maintenance applications.

Before use, ensure the tube or port is depressurized and, where applicable, isolated from any live gas, refrigerant, or electrical systems. The brush can be operated manually or chucked into a variable-speed drill at low RPM for faster cleaning. Inspect bristles before use and discard if wires are bent, broken, or separating from the stem.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Length\u003c\/strong\u003e: 4 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\u003eBristle Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction Type\u003c\/strong\u003e: Double Stem, Single Spiral\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: 0.16 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: 93631\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHAEFER BRUSH","offers":[{"title":"Default Title","offer_id":51544633999666,"sku":"93631","price":23.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7edd4029f350c3007792f35521dae318.jpg?v=1785932184","url":"https:\/\/voomisupply.com\/products\/schaefer-brush-93631-tube-brush-15-16-in-brass-bristles","provider":"Voomi Supply","version":"1.0","type":"link"}
