Schaefer Brush 43382 Spiral Tube Brush 5 in 7.5 in Oal

Product Description

The SCHAEFER BRUSH 43382 is a double stem spiral tube brush designed for cleaning the interior of pipes, tubes, and cylindrical passages in industrial and mechanical service applications. The brush head measures 5 inches in diameter with a 4.5-inch brush length, providing substantial scrubbing coverage across the full working stroke. Total assembly length is 7.5 inches. The tempered steel wire fill delivers firm, consistent bristle pressure against tube walls, making it well suited for removing scale, debris, and fouling from metal pipe interiors. Licensed plumbers, HVAC technicians, and mechanical service contractors are the primary installers and users of this tool.

This tube brush fits maintenance and cleaning tasks on boilers, heat exchangers, condensers, and piping systems where a 5-inch diameter brush is required. The 1/4-inch male NPT connection allows the brush to thread directly onto standard pipe handles or drill adapters, enabling both manual and power-assisted cleaning. It is commonly used in commercial and residential mechanical rooms during routine service, pre-inspection cleaning, and system rehabilitation work where tube-side fouling has reduced system efficiency.

Key Features

• 5-inch diameter brush head for full-contact cleaning in matched bore sizes
• Tempered steel wire fill provides firm bristle pressure for scale and debris removal
• Double stem spiral construction maintains brush shape and concentricity under load
• 1/4-inch male NPT connection threads onto standard pipe handles or drill chucks
• 4.5-inch brush length delivers extended working reach per stroke

Compatibility

Designed as a standard-fitment spiral tube brush for pipes and tubes with an internal diameter of approximately 5 inches, compatible with any handle or extension rod fitted with a 1/4-inch female NPT threaded connection.

Installation Notes

This brush is installed and used by licensed plumbers, HVAC technicians, and mechanical service contractors performing tube and pipe cleaning operations. Before cleaning any piping system, shut off fluid flow and depressurize the line in accordance with site safety procedures and applicable codes. Thread the 1/4-inch male NPT end securely onto a compatible handle or extension rod before use. Do not force a 5-inch brush into a bore smaller than its rated diameter, as this can deform the brush and damage tube walls.
