The brush head is made from Tampico fiber, a natural plant-based bristle material well suited for general-purpose scrubbing and cleaning without scratching metal or plastic surfaces. The brush measures 4 inches in diameter with a 4.5 inch brush length and an 8 inch overall length. A 1\/4 inch NPSM male threaded connection allows the brush to attach to standard extension handles or cleaning rods, making it practical for both handheld and extended-reach applications. This type of brush is commonly used in plumbing, HVAC, and industrial maintenance work.\u003c\/p\u003e\u003cp\u003eThis tube brush is suited for residential and light commercial applications where a 4 inch diameter bore or tube requires periodic cleaning or debris removal. Typical uses include cleaning heat exchanger tubes, drain lines, pipe interiors, and similar cylindrical passages. The Tampico fiber construction makes it appropriate for use on surfaces where wire bristles would cause damage or leave metallic contamination. Plumbers, HVAC technicians, and general maintenance professionals routinely keep brushes of this type in service kits for scheduled cleaning tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTampico fiber bristles provide effective scrubbing without scratching tube walls\u003c\/li\u003e\n\u003cli\u003e4 inch brush diameter sized for standard tube and pipe cleaning tasks\u003c\/li\u003e\n\u003cli\u003e4.5 inch brush length delivers adequate contact area inside the bore\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPSM male thread connection compatible with common extension handles\u003c\/li\u003e\n\u003cli\u003e8 inch overall length suitable for direct handheld use or short-reach cleaning\u003c\/li\u003e\n\u003cli\u003eSingle spiral construction distributes bristle pressure evenly around the tube interior\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard service brush for 4 inch diameter tube and pipe cleaning applications in plumbing, HVAC, and general industrial maintenance.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eShut off water supply and relieve system pressure before inserting the brush into any pressurized line or fitting.
