Schaefer Brush 43628 Tube Brush 7/8 in Brass Bristles

Product Description

The SCHAEFER BRUSH 43628 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and bores. The brass bristle construction provides effective scrubbing action while remaining gentle enough to avoid scoring softer metal surfaces. The brush measures 7/8 inch in diameter with an overall length of 6-1/4 inches and a brush length of 4 inches. It features a 12-24 female threaded connection for attachment to extension rods or compatible handles. Plumbers, HVAC technicians, and maintenance professionals use this brush for tube cleaning, port clearing, and general bore maintenance tasks.

This tube brush suits residential and light commercial applications where thorough interior cleaning of small-diameter tubing is required. Common uses include cleaning heat exchanger tubes, refrigerant line ports, condensate drain openings, and small-bore plumbing fittings. The brass construction resists corrosion and is compatible with many common cleaning solutions used in HVAC and plumbing service work. The 12-24 female threaded end allows connection to standard extension handles for reach in confined or deep installations.

Installation Notes

Ensure any system, circuit, or equipment being serviced is fully de-energized or depressurized before inserting the brush into ports or tubing. Thread the brush securely onto the extension rod before use to prevent it from detaching inside a tube. Technicians should wear appropriate eye and hand protection when using tube brushes with cleaning agents. Follow applicable safety and maintenance standards for the specific system being serviced.
