Pro-source 06689 Single Spiral Nylon Tube Brush 0.75in

Product Description

The PRO-SOURCE 06689 is a single spiral tube brush designed for cleaning the interior of pipes, tubes, and cylinders. The brush head measures 0.75 inches in diameter and 4.5 inches in length, with an overall length of 42 inches that gives reach into deep bores and long tube runs. Nylon bristles with a 0.01 inch filament diameter provide effective scrubbing action without aggressive abrasion, making this brush suitable for removing deposits, scale, or debris from metal and non-metal tube interiors. The galvanized steel shank measures 0.142 inches in diameter and supports the full 42 inch working length.

This brush is used in plumbing, HVAC, and industrial maintenance applications where tube interior cleaning is required. It fits standard tube brush drill adapters and can be used manually or with a low-speed rotary driver. Typical applications include cleaning heat exchanger tubes, condenser tubes, copper water lines, and similar bore work encountered during service and preventive maintenance routines. Trade professionals including plumbers, HVAC technicians, and maintenance mechanics reach for this style of brush when prepping tube surfaces for inspection or reassembly.

Designed for use in tubes and pipe bores with an internal diameter close to 0.75 inches. Compatible with standard tube brush holders and low-speed rotary drill adapters accepting a 0.142 inch shank.

Installation Notes

When used with a rotary driver, keep speeds low to avoid bristle distortion or shank whip across the full 42 inch length. Secure the workpiece or tube assembly before brushing to prevent movement during cleaning. Inspect the shank for bending before each use, as a bent shank on a long brush can cause erratic rotation. This tool requires no special certifications to use but should be handled per shop safety practices when working near open pipe ends.
