Constructed with a very fine grade aluminum oxide abrasive mineral, the star-tip geometry delivers consistent radial pressure across the full bore of the workpiece. At 4 inches in diameter and weighing 0.03 pounds, this brush is built for controlled material removal without aggressive cutting action. It is used by plumbers, pipefitters, and HVAC technicians who need a reliable, repeatable finish inside tube ends prior to joining or inspection.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for light deburring, surface prep, and cleaning inside pipe and tube inner diameters in both residential and commercial applications. The very fine abrasive grade makes it appropriate for finish work where aggressive stock removal would damage the bore surface or compromise a seal surface. Typical applications include copper, steel, and stainless tube preparation ahead of soldering, brazing, or mechanical coupling installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStar-tip design provides consistent inward pressure for uniform contact across the full interior bore\u003c\/li\u003e\n  \u003cli\u003eVery fine grade aluminum oxide abrasive for controlled, light surface conditioning\u003c\/li\u003e\n  \u003cli\u003e4 inch diameter suits standard pipe and tube ID cleaning applications\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.03 pounds for easy handling in confined spaces\u003c\/li\u003e\n  \u003cli\u003eDurable construction supports repeated use across multiple service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement surface conditioning brush for use in 4 inch inside-diameter pipe and tube cleaning and finishing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is installed by HVAC technicians, plumbers, and pipefitters using standard low-speed rotating tools or manual chucking equipment. Always depressurize and isolate the pipe or tube section before beginning any internal surface work. Wear appropriate eye protection and gloves when operating rotary abrasive tools.
