Schaefer Brush 43816 Spiral Tube Brush 5/8 in Stainless

Product Description

The SCHAEFER BRUSH 43816 is a double stem spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore passages. It features stainless steel bristles mounted on a stainless steel stem, making it suitable for applications where corrosion resistance and durability are required. The brush measures 5/8 inch in diameter with an overall length of 6 inches and a brush scrubbing length of 4 inches. It connects via a 12-24 female threaded fitting, allowing it to attach to standard extension rods or handles. HVAC technicians, plumbers, and industrial maintenance professionals typically reach for this style of brush when clearing scale, debris, or fouling from tube interiors.

This tube brush is well suited for residential and light commercial maintenance work involving heat exchangers, condenser tubes, drain lines, and similar small-bore components. The 5/8 inch diameter targets tubing in that size range commonly found in HVAC coil assemblies, plumbing fittings, and general-purpose pipe cleaning tasks. The 12-24 female thread connection is a standard size that mates with widely available extension handles and drill adapters, making it practical for both hand-powered and low-speed rotary cleaning applications.

Key Features

• Stainless steel bristles resist corrosion and hold up to repeated use in wet or chemically active environments
• Double stem spiral construction provides consistent radial bristle contact along the full brush length
• 5/8 inch diameter targets standard small-bore tubes and pipe interiors
• 4 inch brush scrubbing length covers adequate tube depth per stroke
• 12-24 female threaded connection accepts standard extension rods and drill adapters
• Lightweight at 0.1 pounds, reducing hand fatigue during repetitive cleaning tasks

Compatibility

Designed as a standard replacement and maintenance brush for use with 5/8 inch inside-diameter tubes and pipes. Compatible with extension handles and rods fitted with a 12-24 male threaded connection.

Installation Notes

Installation and use of this brush does not require electrical or gas shutoff, but always depressurize and drain any pipe, tube, or coil assembly before inserting the brush. Thread the brush securely onto the extension handle or rod before use to prevent separation during cleaning. When using with a rotary tool or drill, keep speed low to avoid bristle distortion or stem fatigue. Dispose of dislodged debris per local waste handling requirements.
