Schaefer Brush 43745 Spiral Tube Brush 2in Nylon

Product Description

The SCHAEFER BRUSH 43745 is a single stem spiral tube brush designed for cleaning the interior of tubes, pipes, and cylindrical passages. The brush measures 2 inches in diameter with an overall length of 7.25 inches and a brush length of 5 inches. Nylon bristles provide effective scrubbing action for removing debris, deposits, and buildup without scratching softer materials. The 1/4-inch male NPSM threaded connection allows it to attach to standard cleaning rods or extension handles. Plumbers, HVAC technicians, and maintenance professionals use this brush in routine pipe and tube maintenance tasks.

This tube brush is suited for residential and light commercial maintenance applications where access to cylindrical openings, tubes, or conduit interiors is required. Its nylon bristle construction makes it appropriate for use on copper, plastic, and other materials where metal bristles could cause surface damage. The NPSM threaded connection is compatible with standard cleaning rod systems commonly used in plumbing and HVAC service work.

Compatibility

Installation Notes

This brush is installed by licensed plumbers and HVAC technicians during scheduled maintenance or service calls. Thread the 1/4-inch male NPSM connection securely onto a compatible cleaning rod or extension before use. Shut off water or fluid flow and depressurize the system before inserting the brush into any pipe or tube. Do not force the brush into openings smaller than the rated 2-inch diameter, as this can damage bristles or restrict brush movement.
