The brush head measures 6 inches in diameter and 4.5 inches in length, with a 7-inch overall length including the stainless steel shank. The shank diameter is 0.25 inches, making it compatible with standard drill chucks and flexible drive cables. Nylon filaments at 0.045 inches in diameter provide firm but non-abrasive scrubbing action, suitable for removing scale, deposits, and debris without damaging softer tube or pipe wall materials. HVAC technicians, plumbers, and maintenance professionals use this brush for tube cleaning during service and preventive maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for both residential and light commercial applications where tube or conduit interior cleaning is required. Common uses include evaporator coil drain tubes, heat exchanger flue passages, condenser tube bundles, and small-diameter pipe bores. The single-spiral construction concentrates bristle contact along the full diameter of the tube bore, ensuring thorough wall coverage in a single pass. The 7-inch overall length allows reach into recessed or hard-to-access passages without requiring extension tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-inch brush diameter for cleaning full-bore contact in matching tube sizes\u003c\/li\u003e\n  \u003cli\u003e4.5-inch brush length with 7-inch overall length including shank\u003c\/li\u003e\n  \u003cli\u003eSingle-spiral configuration provides consistent bristle coverage along the tube wall\u003c\/li\u003e\n  \u003cli\u003eNylon fill material at 0.045-inch filament diameter for non-abrasive scrubbing\u003c\/li\u003e\n  \u003cli\u003eStainless steel shank resists corrosion in wet or chemical cleaning environments\u003c\/li\u003e\n  \u003cli\u003e0.25-inch shank diameter fits standard drill chucks and drive adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-service tube brush for use in any application requiring cleaning of a 6-inch-diameter cylindrical bore or tube interior.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is installed by trade professionals including HVAC technicians and plumbers during routine maintenance or service calls.
