Schaefer Brush 42950 Tampico Fiber Tube Brush 2.5in

Product Description

The SCHAEFER BRUSH 42950 is a single stem, single spiral tube brush constructed with Tampico fiber bristles and designed for cleaning the interior of tubes, pipes, and cylindrical passages. With a 2.5-inch brush diameter and an 8-inch overall length, this brush reaches into tight passages while delivering consistent scrubbing contact along the full 4.5-inch brush length. The 1/4-inch male NPSM connection allows fast attachment to standard extension rods or handheld handles. Tampico fiber is a natural agave-derived material well suited for wet or dry cleaning applications where a non-scratching, moderately stiff bristle is required. HVAC technicians, plumbers, and maintenance professionals use this brush for tube cleaning in heat exchangers, condensers, and drain lines.

This tube brush is used in residential and light commercial maintenance applications wherever interior bore cleaning is required. Typical uses include heat exchanger tubes, copper and PVC drain lines, condenser tubes, and similar cylindrical passages in the 2.5-inch diameter range. The single spiral configuration delivers uniform bristle contact and consistent scrubbing action around the full circumference of the bore. The 1/4-inch male NPSM fitting makes it compatible with standard extension rod systems commonly used in tube-cleaning setups.

Key Features

• Tampico fiber bristles provide moderate stiffness with no metal-to-metal contact, protecting tube walls from scratching
• 2.5-inch brush diameter for consistent contact inside standard tube and pipe bores
• 4.5-inch brush length covers a meaningful cleaning stroke per pass
• 8-inch overall length allows reach into shallow tube sheets and short tube runs
• 1/4-inch male NPSM connection threads onto standard extension rods and handles
• Single stem, single spiral construction for straightforward, reliable cleaning action

Compatibility

Designed as a standard-fitment tube brush for use with 1/4-inch NPSM extension rods and brush handles; suited for tube and pipe interior cleaning applications in the 2.5-inch diameter range.

Installation Notes

Thread the 1/4-inch male NPSM connection securely onto the extension rod or handle before inserting into the tube bore. Shut off and isolate any fluid flow through the system before cleaning to avoid debris displacement into active lines. Use appropriate personal protective equipment when cleaning tubes that have carried chemicals, scale, or biological matter. Inspect bristle condition before each use and replace the brush when fiber wear reduces effective diameter contact.
