Schaefer Brush 43386 Spiral Tube Brush 7 in 7.5 in Oal

Product Description

The SCHAEFER BRUSH 43386 is a double stem spiral tube brush designed for cleaning the interior of pipes, tubes, and cylindrical passages. 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.

This 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.

Installation Notes

This 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. Avoid forcing the brush through restrictions smaller than its rated diameter, as this can damage the wire fill or deform the stems.
