The brush spans 7 inches in diameter and 7.5 inches overall length, with a 4.5-inch brush length that reaches deep into bore surfaces. Tempered steel wire construction delivers durable scrubbing action against scale, debris, and deposits. Connection is made via a 1\/4-inch male NPT fitting, allowing the brush to thread directly onto standard pipe handles or extension rods. Plumbers, HVAC technicians, and pipe service crews keep this brush on hand for routine maintenance and cleaning tasks.\u003c\/p\u003e\u003cp\u003eThis brush is suited for residential and light commercial maintenance work where thorough tube and pipe interior cleaning is required. Typical applications include boiler tube cleaning, condenser tube service, pipe reconditioning, and general bore cleaning during system maintenance or installation prep. The NPT male connection makes it easy to attach to threaded drive handles or power drill adapters for faster turnaround on repetitive cleaning work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-inch brush diameter provides full-coverage contact inside matching bore sizes\u003c\/li\u003e\n\u003cli\u003e4.5-inch brush length reaches into deep or recessed tube interiors\u003c\/li\u003e\n\u003cli\u003eTempered steel wire fill offers aggressive scrubbing action for scale and deposit removal\u003c\/li\u003e\n\u003cli\u003e1\/4-inch male NPT connection threads onto standard pipe handles and extension rods\u003c\/li\u003e\n\u003cli\u003eDouble stem spiral design keeps the brush centered and maintains consistent wall contact\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or service brush for tube and pipe cleaning applications requiring a 7-inch diameter, 1\/4-inch male NPT connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis brush is installed by plumbers, HVAC technicians, and pipe service professionals. Before use, shut off and depressurize any pipe or system being serviced. Thread the 1\/4-inch male NPT fitting securely onto a compatible handle or extension rod before inserting the brush into the bore.
