Mill-rose 64100 Refrigeration Brush 1-3/8 in Od

Product Description

The MILL-ROSE 64100 is a heavy-duty refrigeration brush built for cleaning tubing, coils, and line sets in refrigeration and HVAC service work. It features a double-spiral, double-stem construction with a heavy-gauge galvanized stem wire that holds its shape under repeated use. The fill wire is spring-tempered stainless steel, making it rust-proof and suitable for wet or oily service environments. The brush measures 1-3/8 inches in outside diameter, sized to fit common refrigeration tubing. HVAC technicians and refrigeration mechanics reach for this brush when cleaning line interiors before brazing or during routine coil and tube maintenance.

This brush is suited for residential and light commercial refrigeration service, including tube cleaning prior to fitting installation, coil cleaning, and condenser or evaporator tube maintenance. The 1-3/8 inch OD size targets standard refrigeration line and tube diameters commonly found in split systems, walk-in coolers, and refrigeration equipment. It is a hand-tool used by HVAC and refrigeration technicians in the field and shop alike.

Key Features

• Double-spiral, double-stem construction for durability and consistent scrubbing action
• Heavy-gauge galvanized stem wire resists bending and holds brush shape
• Spring-tempered stainless steel fill wire is rust-proof for refrigeration and wet environments
• 1-3/8 inch outside diameter fits standard refrigeration tubing
• Straight wire fill design for effective interior tube cleaning

Compatibility

Designed as an OEM-style replacement brush for refrigeration and HVAC tube-cleaning applications where a 1-3/8 inch OD straight wire brush is required.

Installation Notes

This brush is a hand-cleaning tool used by HVAC and refrigeration technicians. Before cleaning any line or tube connected to a live system, recover refrigerant and isolate the line per EPA Section 608 requirements. Insert the brush with steady, even strokes to avoid bending the stem in tight bends or fittings. Inspect the brush for worn or splayed fill wire before each use and replace when cleaning performance drops.
