Schaefer Brush 43633 Tube Brush 1 in Brass Bristles

Product Description

The SCHAEFER BRUSH 43633 is a double stem, single spiral tube brush designed for cleaning the interior of tubes, pipes, and bores. The brush features a 1 inch diameter and a 6.25 inch overall length, with a 4 inch brush scraper length that delivers consistent contact along the working surface. Brass bristles provide effective scrubbing without the risk of scratching softer metal surfaces. The 12-24 female threaded connection allows the brush to be attached to compatible extension rods for deeper reach into tubes or heat exchanger passages. This brush is suited for use by HVAC technicians, plumbers, and maintenance professionals.

This tube brush is used in applications that require internal bore cleaning, including heat exchanger tubes, condenser tubes, copper pipe fittings, and similar cylindrical passages. The brass bristle construction makes it appropriate for use on copper, brass, aluminum, and other non-ferrous surfaces where steel bristles would be too aggressive. It is well suited for both shop bench work and field service tasks in residential and light commercial HVAC and plumbing applications.

Installation Notes

Ensure the tube or pipe to be cleaned is isolated from flow and depressurized before inserting the brush. Thread the brush securely onto any compatible 12-24 extension rod before use to prevent separation inside the tube. Use appropriate personal protective equipment when cleaning heat exchanger or condenser tubes that may contain chemical residues or scale buildup. Inspect bristle condition before each use and replace the brush if bristles are bent, compressed, or significantly worn.
