Schaefer Brush 43619 Tube Brush Brass 11/16 in 6-1/4 in Oal

Product Description

The SCHAEFER BRUSH 43619 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and bores. The brush measures 11/16 inches in diameter with an overall length of 6.25 inches and a brush working length of 4 inches. Brass bristles provide effective scrubbing action while remaining gentle enough to avoid scoring softer metal surfaces. The 12-24 female threaded connection allows the brush to attach to extension rods or compatible handles, making it practical for reaching into confined passages. Technicians in HVAC, plumbing, and general maintenance use this type of brush to remove scale, debris, and fouling from tube interiors during service and repair work.

This tube brush is suited for cleaning small-diameter tubes and bores in residential and commercial applications. Typical uses include clearing heat exchanger tubes, condenser tubes, refrigeration coils, and similar passages where deposits accumulate over time. The brass bristle construction makes it appropriate for use on copper, brass, and other non-ferrous tubing without risk of ferrous contamination. The threaded female connection accommodates standard extension rods when additional reach is required.

Key Features

Compatibility

Designed as an OEM-style replacement and general-service tube brush for small-bore cleaning applications where a 11/16 inch diameter brass-bristle brush with a 12-24 female threaded connection is required.

Installation Notes

This brush is installed by hand or with a compatible handle or extension rod using the 12-24 female threaded connection. Ensure the tube or bore is depressurized and isolated from any fluid flow before inserting the brush. Inspect bristles for wear or splaying before use and replace if the working diameter is significantly reduced. Use of appropriate personal protective equipment is recommended when clearing scale or chemical deposits from tube interiors.
