Pro-source MCN21105 Double Spiral Tube Brush 1.5in

Product Description

The PRO-SOURCE MCN21105 is a double stem, double spiral tube brush built for cleaning the interior walls of tubes, pipes, and bores. The brush body is constructed from tempered steel wire, providing firm, consistent scrubbing action on residue, scale, and debris. At 1.5 inches in diameter and 4.5 inches in brush length, it reaches deep into tight passages while the 7.5-inch overall length keeps the technician clear of the work surface. The threaded male connection — 0.25 inch NPT — attaches directly to standard extension rods or drill adapters. HVAC technicians, plumbers, and industrial maintenance crews use this brush for routine tube and port cleaning during service calls and equipment overhauls.

This tube brush suits residential and light commercial applications where internal bore cleaning is required. Common uses include heat exchanger tube cleaning, condenser tube maintenance, and pipe bore preparation before fitting installation. The round, double spiral design distributes bristle contact evenly around the tube wall, making it effective on metal tubing in HVAC coils, boiler tubes, and plumbing assemblies. The 0.25 inch MNPT threaded stem allows connection to standard brush extension rods for added reach in confined equipment spaces.

Key Features

• Tempered steel wire bristles deliver firm scrubbing action on scale and debris inside tubes and bores
• Double stem, double spiral construction provides even bristle distribution around the full tube wall circumference
• 1.5 inch diameter fits standard tube and pipe bore sizes common in HVAC and plumbing service work
• 0.25 inch MNPT threaded connection is compatible with standard extension rods and drill adapters

• Round shape and rigid bristle flexibility maintain consistent contact pressure throughout the stroke

Compatibility

Designed as a replacement-style tube brush for use with standard 0.25 inch NPT brush extension rod systems in residential and commercial HVAC, boiler, and plumbing tube-cleaning applications.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or qualified maintenance personnel. Power down and de-energize all associated equipment before accessing heat exchangers or tube bundles, and verify that systems are depressurized before inserting the brush. Thread the 0.25 inch MNPT stem securely into the extension rod or drill adapter before use to prevent separation during the cleaning stroke. Dispose of dislodged scale and debris in accordance with local waste disposal requirements.
