The brush connects via a 1\/4-inch NPSM male fitting, making it compatible with standard chimney rod systems used by sweeps and HVAC technicians. Tempered steel wire holds its shape under repeated mechanical stress and maintains stiffness in high-residue flues. This brush is suited for chimney maintenance work in both residential and light commercial settings where a round flue requires a direct, rigid-bristle cleaning tool.\u003c\/p\u003e\u003cp\u003eThe 36408 is designed for round flue applications where the 8-inch diameter matches the interior dimension of the liner. It is commonly used during annual chimney inspections, pre-season fireplace service calls, and post-install cleaning of new liner systems. Chimney sweeps, HVAC technicians, and plumbers servicing gas appliance venting systems are the primary users. The 1\/4-inch NPSM male connection threads onto flexible or rigid chimney rods sold separately.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-inch diameter round profile sized for matching flue liner interiors\u003c\/li\u003e\n\u003cli\u003eTempered steel wire bristles provide firm, durable scrubbing action\u003c\/li\u003e\n\u003cli\u003e1\/4-inch NPSM male connection fits standard chimney rod systems\u003c\/li\u003e\n\u003cli\u003eRound shape ensures full contact with circular flue walls\u003c\/li\u003e\n\u003cli\u003eDesigned for creosote, soot, and debris removal in residential and commercial chimneys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service brush for round flue liner systems requiring an 8-inch diameter round chimney brush with a 1\/4-inch NPSM male rod connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed chimney sweep or qualified HVAC technician should perform flue cleaning in accordance with applicable NFPA 211 guidelines. Shut down and allow the appliance to cool completely before inserting any brush into the flue. Inspect the connection between the brush and chimney rod before each use to confirm secure threading.
