At 72 inches in overall length and 0.44 inches in diameter, the extension connects via a 3\/8 inches NPSM female thread on one end and a 3\/8 inches NPSM male thread on the other, allowing users to link multiple extensions together or attach directly to compatible brush handles. The fiberglass construction keeps the extension lightweight and resistant to moisture and corrosion, making it practical for wet or chemical-exposure environments. HVAC technicians, plumbers, and maintenance professionals install this extension when standard-length brush handles fall short of the work area.\u003c\/p\u003e\n\u003cp\u003eThis extension is suited for tube cleaning, pipe brushing, and scraping tasks in residential and commercial settings. It is commonly used when servicing heat exchangers, flue passages, condenser tubes, and drain lines where direct hand access is not possible. The 72 inches length provides substantial reach into deep or vertical runs without requiring the technician to reposition frequently. The threaded ends are compatible with standard 3\/8 inches NPSM brush handle fittings, making it straightforward to build out a longer assembly using multiple extensions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e72 inches overall length for extended reach into deep passages and vertical runs\u003c\/li\u003e\n  \u003cli\u003eFiberglass construction resists moisture, corrosion, and many cleaning chemicals\u003c\/li\u003e\n  \u003cli\u003e0.44 inches diameter provides a rigid yet manageable working profile\u003c\/li\u003e\n  \u003cli\u003e3\/8 inches NPSM female and male threaded ends allow stacking of multiple extensions\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard tube brushes and scrapers using 3\/8 inches NPSM fittings\u003c\/li\u003e\n  \u003cli\u003eSold individually, packaged as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with tube brushes and scrapers that accept 3\/8 inches NPSM threaded handle connections.
