The brush head is constructed from Tampico fiber, a natural plant-based filament that provides firm yet non-abrasive scrubbing action suited to moderate-duty cleaning applications. At 3.5 inches in diameter and 8 inches in overall length, with a 4.5-inch brush section, this tool reaches deep into tube interiors. The 1\/4-inch NPSM male connection allows it to thread onto standard extension rods or handles for added reach. It is a practical hand tool for HVAC, plumbing, and industrial maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for residential and light commercial maintenance tasks where tube or pipe bore cleaning is required. Typical applications include heat exchanger tube cleaning, condenser tube maintenance, drain line brushing, and pipe bore preparation prior to fitting or inspection. The Tampico fiber fill is compatible with water and mild cleaning solutions, making it a reliable choice for wet or dry scrubbing operations where a non-metallic filament is preferred to avoid scratching or damaging the tube wall surface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTampico fiber fill provides firm, non-abrasive scrubbing action safe for tube wall surfaces\u003c\/li\u003e\n  \u003cli\u003e3.5-inch brush diameter for full-contact cleaning inside matched tube bores\u003c\/li\u003e\n  \u003cli\u003e4.5-inch brush length delivers extended scrubbing coverage per pass\u003c\/li\u003e\n  \u003cli\u003e8-inch overall length allows reach into recessed tube openings\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPSM male connection is compatible with standard extension rods and handles\u003c\/li\u003e\n  \u003cli\u003eSingle stem, single spiral construction maintains consistent fill density along the brush section\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style maintenance brush for use with standard 1\/4-inch NPSM extension rod systems in tube and pipe cleaning applications across HVAC, plumbing, and industrial service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis brush is installed and used by HVAC technicians, plumbers, and industrial maintenance personnel. Before cleaning any tube or heat exchanger, isolate and de-energize the associated system and relieve any fluid pressure in accordance with applicable safety procedures.
