Pro-source 05027 Brass Twisted Wire Bristle Brush

Product Description

The PRO-SOURCE 05027 is a single-spiral brass twisted wire bristle brush designed for cleaning bores, tubes, ports, and threaded fittings in HVAC, plumbing, and general mechanical service applications. The brush head measures 1.5 inches in length with a 0.25-inch diameter, and the overall assembly reaches 7 inches in length, giving technicians adequate reach into confined passages. Brass fill wire at 0.005 inches in diameter delivers firm but non-damaging abrasion suitable for soft metals, copper tubing, and plastic-lined passages. The 0.085-inch galvanized steel shank fits standard drill chucks or can be used by hand.

This brush is well suited for residential and light commercial trade use. HVAC technicians use brushes of this type to clean orifice passages, pilot tubes, and metering ports. Plumbers use them to clean sweat-fitting interiors and threaded connections before reassembly. The compact 0.25-inch head diameter targets small-bore applications where larger brushes cannot enter. The single-spiral construction maintains consistent contact around the full bore circumference during rotation.

Compatibility

Designed as an OEM-style replacement brush for small-bore cleaning tasks in residential and commercial HVAC, plumbing, and mechanical service applications requiring a 0.25-inch diameter single-spiral twisted wire brush.

Installation Notes

This brush is installed and used by HVAC technicians, plumbers, and mechanical service professionals. Always de-energize and lock out equipment and shut off gas or water supply before probing any internal passage. When used in a rotary tool or drill, secure the shank fully in the chuck before operation to prevent ejection. Inspect the brush for bent or loose bristles before each use and replace if damaged.
