Schaefer Brush 43507 Tube Brush 7/16 in Stainless Steel

Product Description

The SCHAEFER BRUSH 43507 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore passages. The stainless steel bristles provide corrosion resistance and durability across repeated uses, making this brush suitable for industrial maintenance, HVAC service, plumbing, and general tube-cleaning applications. The brush measures 7/16 inch in diameter with an overall length of 6-1/4 inches and a brush or scraper length of 4 inches. The 12-24 female threaded connection allows the brush to attach to compatible extension rods for reaching into deeper passages. Licensed trade professionals and maintenance technicians keep this type of brush on hand for heat exchanger tubes, condenser coils, and similar precision-bore cleaning tasks.

This tube brush fits applications requiring a compact, small-diameter cleaning tool. The 7/16 inch diameter targets narrow tube bores found in residential and light commercial HVAC equipment, refrigeration coils, plumbing fittings, and mechanical assemblies. The 12-24 female threaded end allows for modular use with threaded extension rods, making it adaptable for varying access depths. Stainless steel construction makes it compatible with most cleaning solutions and resists degradation in wet or chemically active environments.

Key Features

• Double stem, single spiral construction provides consistent bristle contact around the full tube bore circumference
• Stainless steel bristles resist corrosion and hold shape through repeated mechanical cleaning cycles
• 7/16 inch diameter fits narrow-bore tubes and passages common in HVAC and refrigeration equipment
• Overall length of 6-1/4 inches with a 4 inch brush or scraper length for targeted cleaning reach
• 12-24 female threaded connection accepts standard extension rods for deeper access
• Lightweight at 0.1 pounds, suited for handheld use or use with a low-speed drill

Compatibility

Designed as a standard small-bore tube brush for use in residential and commercial maintenance applications where a 7/16 inch diameter, 12-24 female threaded brush is required.

Installation Notes

This brush is installed by threading it onto a compatible 12-24 male-threaded extension rod or handle. When using with a power drill, keep rotational speed low to prevent bristle flare or stem deformation. Ensure the tube or bore being cleaned is depressurized and, where applicable, that the system is shut down and de-energized before inserting the brush. Inspect bristles for wear or bending before each use and replace if the brush diameter has noticeably reduced.
