Pro-source 05190 Nylon Bristle Tube Brush 3/16 Inch

Product Description

The PRO-SOURCE 05190 is a single-spiral nylon bristle tube brush designed for cleaning small-diameter bores, tubes, ports, and passages. The brush head measures 1 inch in length with a 3/16-inch diameter, and the overall assembly extends to 4 inches, allowing reach into confined spaces without requiring extension tools. The 0.003-inch nylon filaments are soft enough to clean without abrading most metal or plastic surfaces. A 0.062-inch stainless steel shank provides rigid support and resists corrosion during wet or chemical cleaning applications. HVAC technicians, plumbers, and maintenance professionals use this brush for port cleaning, orifice maintenance, and tube preparation work.

This brush is suited for light-duty bore cleaning in residential and commercial service applications. Typical uses include cleaning refrigerant ports, drain orifices, pilot orifice assemblies, small copper or PVC tube ends, and threaded fittings before assembly. The nylon fill makes it compatible with most solvents and cleaning solutions without filament degradation. The stainless steel shank allows the brush to be used in both hand-tool and low-speed rotary applications.

Key Features

• 1-inch brush length and 3/16-inch diameter for small-bore cleaning applications
• Single-spiral construction provides consistent bristle contact along the bore
• 0.003-inch nylon filaments are non-abrasive and compatible with metal and plastic surfaces
• 0.062-inch stainless steel shank resists corrosion and provides rigid support
• 4-inch overall length allows reach into recessed ports and passages

Compatibility

Designed as a general-purpose small-bore tube brush suited for use in HVAC, plumbing, and mechanical maintenance applications where a 3/16-inch brush diameter is required.

Installation Notes

A licensed HVAC technician, plumber, or qualified maintenance professional should ensure the system or component is depressurized and de-energized before inserting any cleaning tool into ports or passages. When used in a rotary application, keep RPM within the range appropriate for the shank diameter to prevent bending or breakage. Inspect filaments before each use and replace the brush if bristles are flattened, frayed, or missing.
