The tapered bristle profile transitions from 0.5 inches at the tip to 1 inch at the base, allowing a single brush to fit a range of tube diameters without swapping tools mid-job. At 30 inches in overall length, the brush reaches deep into boiler tubes and flue sections. Horsehair bristles provide effective scrubbing action on metal surfaces without causing scoring. Licensed HVAC technicians and boiler service professionals are the primary installers and users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis brush is suited for routine maintenance and seasonal cleaning of residential and light commercial boilers, including water-tube and fire-tube configurations. It is used during annual boiler cleanings to clear combustion deposits from flue passages and tube interiors, helping maintain heat transfer efficiency and safe operation. The tapered design makes it practical for boiler tubes that vary slightly in inside diameter across a single unit. Each pack contains 6 brushes, supporting service fleets and shops that clean multiple units per route.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTapered profile spans 0.5 to 1 inch in diameter for multi-size tube fitment\u003c\/li\u003e\n  \u003cli\u003e30-inch overall length provides reach into deep boiler tubes and flue sections\u003c\/li\u003e\n  \u003cli\u003eHorsehair bristles deliver firm scrubbing action without scoring metal surfaces\u003c\/li\u003e\n  \u003cli\u003eSold in a 6-pack quantity, suited for service shops and multi-unit maintenance routes\u003c\/li\u003e\n  \u003cli\u003ePurpose-built for boiler and flue cleaning applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on boiler tubes and flue passages with inside diameters ranging from 0.5 to 1 inch.
