With a large end diameter of 2.5 inches, it reaches and scrubs the interior surfaces of fittings, valve bodies, heat exchanger tubes, conduit ends, and similar hollow passages. Technicians in HVAC, plumbing, and general mechanical service use spoke brushes to remove scale, debris, oxidation, and residue before assembly or inspection. The 90422 weighs 0.3 pounds, making it a lightweight hand tool suited for bench work and field service alike.\u003c\/p\u003e\u003cp\u003eSpoke brushes of this type see regular use in trade applications where internal surfaces must be cleaned before sealing, soldering, brazing, or threading. The 2.5-inch large end diameter suits mid-to-large bore fittings and pipe connections common in commercial plumbing and HVAC mechanical rooms. HVAC technicians, pipefitters, and plumbers reach for spoke brushes during maintenance, retrofit, and new installation work when bore cleanliness directly affects joint integrity or component fit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLarge end diameter of 2.5 inches for cleaning mid-to-large bore openings\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.3 pounds for easy one-handed use in tight spaces\u003c\/li\u003e\n\u003cli\u003eSpoke-style bristle design reaches and scrubs interior bore surfaces evenly\u003c\/li\u003e\n\u003cli\u003eSold individually as a single-unit package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose spoke brush suitable for cleaning cylindrical bores and tubular openings with an inside diameter compatible with a 2.5-inch large end brush profile.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eUse appropriate personal protective equipment, including gloves and eye protection, when brushing debris from bore surfaces.
