Pro-source 05107 Brass Twisted Wire Bristle Brush 3/4 in

Product Description

The PRO-SOURCE 05107 is a brass twisted wire bristle brush designed for cleaning bores, tubes, and small-diameter passages in plumbing, HVAC, and mechanical service applications. The brush head measures 2.5 inches long by 0.75 inches in diameter, with a 9-inch overall length that provides reach into fittings, valve bodies, and heat exchanger ports. Wire diameter is 0.008 inches, delivering moderate flex without excessive abrasion. The galvanized steel shank measures 0.142 inches in diameter and accepts standard drill chucks or can be used by hand. Licensed tradespeople and experienced service technicians install and use this tool during routine maintenance and repair procedures.

This brush is suited for residential and light commercial service work where internal bore cleaning is required before soldering copper fittings, threading pipe connections, or inspecting valve seats. The single-spiral fill pattern provides consistent bristle contact around the full circumference of the bore. Its 9-inch overall length makes it practical for reaching into assembled piping sections without disassembly in many common scenarios.

Installation Notes

Isolate and depressurize any system before inserting the brush into live plumbing or refrigerant lines. When used with a power drill, start at low speed to maintain control and avoid bending the shank. Wear appropriate eye protection, as brass bristles can shed during aggressive use. Follow applicable codes and manufacturer procedures for the system being serviced.
