Schaefer Brush 43636 Tube Brush 1-1/4 in Brass Bristles

Product Description

The SCHAEFER BRUSH 43636 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and bores. The brush features brass bristles wound on a brass core and measures 1-1/4 inches in diameter with an 8-inch overall length. The brush length itself is 4-1/2 inches, providing focused scrubbing action within the bore. A 1/4-inch NPSM male connection at the stem end allows the brush to be threaded onto an extension handle or used with compatible drive equipment. Plumbers, HVAC technicians, and maintenance professionals use this brush for routine cleaning and descaling tasks during service calls or equipment maintenance.

This tube brush is well suited for residential and light commercial service applications where tube and pipe interiors require periodic cleaning. Typical uses include condenser tube cleaning, heat exchanger maintenance, boiler tube service, and general pipe bore preparation. The brass bristle construction makes it appropriate for use on softer metals and surfaces where steel bristles would cause unwanted abrasion. The threaded male connection allows use with standard extension rods for reaching into deeper tube runs.

Key Features

• Double stem, single spiral construction provides consistent bristle contact along the tube wall
• Brass bristles and brass core resist corrosion and are safe for use on copper, aluminum, and other soft-metal tube surfaces
• 4-1/2-inch brush length targets cleaning action within the bore without excess flex
• 1/4-inch NPSM male connection threads onto standard extension handles and drive rods
• Compact 8-inch overall length suits confined service access points

Compatibility

Designed as an OEM-style replacement and general-service tube brush for use in residential and commercial applications requiring a 1-1/4-inch diameter bore brush with a 1/4-inch NPSM male threaded connection.

Installation Notes

This brush is installed by a licensed plumber, HVAC technician, or qualified maintenance technician. Before servicing any tube bundle or heat exchanger, shut down the associated equipment, relieve system pressure, and isolate the fluid circuit per the equipment manufacturer's lockout/tagout procedure. Thread the brush onto a compatible extension rod hand-tight before use. Inspect bristles for wear or deformation before each use and replace the brush if bristle loss or core damage is observed.
