Schaefer Brush 43807 Spiral Tube Brush 7/16 in Stainless

Product Description

The SCHAEFER BRUSH 43807 is a double stem spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore passages. The brush features stainless steel bristles wound in a spiral pattern around a stainless steel double stem core, delivering durable scrubbing action in demanding cleaning applications. With a 7/16 inch brush diameter and 6 inch overall length, including a 4 inch brush section, it fits a range of small-diameter openings. The 12-24 female threaded connection allows it to attach to standard extension rods for extended reach. Weighing 0.1 pounds, it is light enough for frequent hand use by HVAC technicians, plumbers, and maintenance professionals.

This tube brush is suited for residential and light commercial maintenance tasks where small-diameter passages require periodic cleaning. Common applications include cleaning heat exchanger tubes, condenser tubes, drain lines, and similar bore passages encountered during HVAC, plumbing, and general mechanical service work. The stainless steel construction makes it appropriate for use in environments where corrosion resistance matters, including wet or chemical-exposed service conditions.

Key Features

• Double stem spiral construction provides consistent contact with tube walls throughout the brush length
• Stainless steel bristles resist corrosion and hold up to repeated use in wet or chemically active environments
• Stainless steel core and stem for full corrosion resistance throughout the assembly
• 7/16 inch brush diameter fits small-bore tubes and passages common in HVAC and plumbing systems
• 4 inch brush section within a 6 inch overall length for effective reach into confined spaces
• 12-24 female threaded connection for attachment to standard extension rods

Compatibility

Designed as an OEM-style replacement and general-purpose tube brush for use with standard 12-24 threaded extension rod systems in HVAC, plumbing, and industrial maintenance applications requiring a 7/16 inch brush diameter.

Installation Notes

This brush is installed by hand or with a compatible 12-24 threaded extension rod — no power tools are required for attachment. Before use in a live system, shut off fluid flow and depressurize or drain the line as required by the applicable service procedure. Avoid forcing the brush through passages significantly smaller than the rated 7/16 inch diameter, as this can damage bristles or deform the stem. Inspect bristles for wear or splaying after extended use and replace when cleaning effectiveness drops.
