Schaefer Brush 43384 Spiral Tube Brush 6 in Tempered Steel

Product Description

The SCHAEFER BRUSH 43384 is a double stem spiral tube brush built for cleaning the interior walls of tubes, pipes, and cylindrical passages. It features a tempered steel wire fill that delivers aggressive scrubbing action against scale, deposits, and debris. The brush measures 6 inches in diameter with a 4.5-inch brush length and a 7.5-inch overall length. It connects via a 1/4 inch male NPT fitting, making it compatible with standard threaded extensions and drive handles. Plumbers, HVAC technicians, and industrial maintenance professionals rely on this style of brush for boiler tube cleaning, heat exchanger service, and pipe rehabilitation work.

This tube brush is suited for residential and commercial maintenance applications where internal tube surfaces require mechanical cleaning. Typical use cases include boiler and chiller tube cleaning, condenser tube service, and drain line maintenance. The double stem spiral construction holds wire fill securely and maintains consistent contact pressure along the full brush length. The 1/4 inch male NPT connection allows the brush to be threaded onto standard extension rods or motorized drive equipment used in tube cleaning operations.

Key Features

• 6-inch diameter fill for thorough tube wall contact in matching bore sizes
• Tempered steel wire construction resists deformation under repeated use
• 4.5-inch brush length provides extended cleaning surface in a single pass
• 1/4 inch male NPT connection threads onto standard extension rods and drive tools
• Double stem spiral design secures fill wire and maintains brush shape during use
• Compact 7.5-inch overall length suits confined-access tube cleaning scenarios

Compatibility

Designed for use with standard 1/4 inch NPT threaded extension rods and tube cleaning drive equipment. Suitable for tubes and bores with an internal diameter matching or close to 6 inches.

Installation Notes

Thread the 1/4 inch male NPT fitting onto a compatible extension rod or drive handle before inserting the brush into the tube bore. Ensure the connected equipment is powered off and depressurized before beginning any tube cleaning procedure. Plumbers and HVAC mechanics typically perform this work; follow applicable safety and maintenance codes for the system being serviced. Inspect the brush fill for wear or deformation after each use and replace if wire strands are damaged or missing.
