Schaefer Brush 42945 Tampico Fiber Tube Brush 2 in

Product Description

The SCHAEFER BRUSH 42945 is a single stem, single spiral tube brush fitted with Tampico fiber bristles, designed for cleaning the interior of tubes, pipes, and conduit in HVAC, plumbing, and light industrial maintenance applications. The brush measures 2 inches in diameter with an overall length of 8 inches and a brush length of 4.5 inches. The 0.25 inch NPSM male connection at the stem end allows the brush to thread onto standard extension rods for reach into longer runs. Tampico fiber is a natural plant-based filament that offers moderate stiffness and is well-suited for scrubbing without scoring softer metal surfaces. Licensed trade technicians and maintenance professionals typically use this tool during tube cleaning, coil cleaning, and drain line service.

This tube brush is used in residential and light commercial service work where internal tube or pipe surfaces need mechanical scrubbing. Common applications include cleaning evaporator drain pans and drain lines, boiler tubes, condenser tubes, and plumbing pipe interiors. The 2-inch brush diameter makes it appropriate for nominal 2-inch tube or pipe bores. The threaded male stem accepts standard extension rod assemblies, making it practical for deep tube cleaning tasks where direct access is limited.

Key Features

• Tampico fiber fill provides moderate scrubbing action without scoring softer metal tube walls
• 2-inch brush diameter suited for nominal 2-inch tube and pipe bores

Compatibility

Designed as an OEM-style cleaning tool for 2-inch nominal bore tubes and pipes in HVAC, plumbing, and light industrial maintenance applications where a 0.25 inch NPSM male threaded stem connection is required.

Installation Notes

Installation and use of this brush does not require electrical or gas shutdown, but any system whose tubes or pipes are being serviced should be depressurized and drained before brushing. A licensed HVAC technician or plumber should verify that the brush diameter matches the tube bore before insertion to avoid bristle damage or lodging. Thread the stem connection to an appropriate extension rod hand-tight before use. Do not force the brush through bends or fittings not designed to pass a rigid brush assembly.
