Pro-source 05164 Single Spiral Nylon Bristle Brush

Product Description

The PRO-SOURCE 05164 is a single spiral nylon bristle brush designed for cleaning, deburring, and surface preparation in tube, bore, and hole applications. The brush measures 3/4 inches in bristle length with a 3/32-inch brush diameter and a 4-inch overall length, making it well-suited for accessing tight passages and small-diameter openings. The 0.003-inch nylon filaments provide gentle but effective scrubbing action without scratching or damaging the work surface. The stainless steel shank measures 0.043 inches in diameter, providing rigidity and corrosion resistance during use. Technicians in HVAC, plumbing, and light industrial trades reach for this style of brush when cleaning orifices, ports, threads, or tubing ends prior to assembly or inspection.

This brush fits standard rotary tool chucks and flex-shaft handpieces that accept a 0.043-inch shank. It is commonly used in field service and shop environments for cleaning burrs from drilled holes, removing debris from valve seats and orifice passages, and prepping threaded fittings before sealing. The nylon fill material makes it appropriate for use on copper, brass, aluminum, and plastic surfaces where wire bristles would cause damage. Residential and light commercial service technicians, plumbers, and pipefitters frequently keep a supply on hand for routine maintenance and fitting preparation tasks.

Installation Notes

Insert the stainless steel shank fully into the tool chuck and tighten securely before operating. Always wear appropriate eye protection when using rotary brushes, as bristle fragments can shed at speed. Confirm the tool speed rating is appropriate for small-diameter brushes before use. Inspect the brush for splayed or broken filaments before each use and replace if damaged.
