11" Round Chimney Brush — Heavy-Duty Oil-Tempered Steel Bristles | 3/8" Male NPT Thread & 3/4" Loop | Fits 11" Flues | For Chimney Brush Rods / 11" Sweep Kit

Built for aggressive flue cleaning, this 11" round chimney brush uses high-tensile, oil-tempered steel bristles to remove soot and deposits from the interior of the flue. The head is sized for 11" diameter flues and is ideal for fireplaces, wood stoves, and chimneys.

A 3/8" Male NPT thread provides a secure, universal connection with most standard fiberglass chimney brush rods, while a 3/4" loop on the opposite end offers extra handling convenience. The double-spiral spindle construction locks each bristle firmly in place so the brush keeps its profile through repeated cleaning cycles and under high-heat flow conditions.

Purpose-built for both professional sweeps and homeowner maintenance, this brush helps restore airflow by loosening creosote and soot. Precision-made for reliable seasonal performance, it’s trusted by industry professionals and homeowners for routine chimney upkeep.
