Schaefer Brush 43283 Flue Brush 2 in Tempered Steel Wire

Product Description

The SCHAEFER BRUSH 43283 is an extra heavy filled double stem single spiral flue brush designed for cleaning flue pipes, vents, and combustion passages in heating equipment. The brush head measures 2 inches in diameter with an overall length of 7.5 inches and a brush length of 4.5 inches. Brush fill is tempered steel wire, providing the stiffness and durability needed to break loose soot, scale, and debris from metal flue surfaces. Connection is a 3/8 inch male NPSM thread, allowing the brush to attach to standard extension rods for extended reach into flue passages. Suited for use by HVAC technicians and chimney service professionals performing routine maintenance or pre-season equipment inspections.

This flue brush is used in residential and light commercial HVAC service applications, primarily for cleaning B-vent, metal flue pipe, and heat exchanger passages in gas-fired furnaces, boilers, and water heaters. The double stem construction and single spiral configuration allow the tempered steel fill to maintain consistent contact with the interior walls of round flue passages. It is a practical tool for technicians who need a durable, threadable brush for vertical or horizontal flue cleaning work.

Key Features

• Extra heavy fill density for aggressive removal of soot and scale deposits
• Double stem single spiral construction maintains consistent wall contact inside round flue passages
• Tempered steel wire fill withstands repeated use against metal flue surfaces
• 3/8 inch male NPSM connection threads onto standard extension rods

Compatibility

Designed as an OEM-style replacement and service brush for round flue and vent pipe passages with a 2 inch inside diameter, compatible with standard 3/8 inch NPSM extension rod systems.

Installation Notes

Installation and use should be performed by a qualified HVAC technician or chimney service professional. Always shut down and allow heating equipment to cool completely before accessing flue passages. Ensure the brush is securely threaded onto the extension rod before insertion to prevent it from becoming lodged inside the flue. Follow applicable local codes and manufacturer guidelines for flue cleaning procedures.
