Schaefer Brush 09744-12 Power Fitting Cleaning Brush

Product Description

The SCHAEFER BRUSH 09744-12 is a stainless steel power fitting and cleaning brush designed for deburring, cleaning, and preparing refrigeration fittings and tubing connections. It features a 0.25-inch inside diameter bore, a 0.4375-inch actual brush diameter, and a 0.25-inch shank diameter with a hex shaft stem for use in a power drill or driver. The overall length is 3.125 inches. Stainless steel fill wire resists corrosion and holds up against refrigeration oils and residues. HVAC and refrigeration technicians rely on this type of brush to clean fitting seats before brazing or flaring operations.

This brush is suited for residential and light commercial HVAC and refrigeration service work. The hex shaft stem allows it to be chucked into a standard drill, making fitting preparation faster compared to hand brushing. The 0.375-inch refrigeration outside diameter corresponds to common copper tubing and fitting sizes encountered in refrigeration line work. It is typically used during line set installation, repair, or system retrofits where clean, oxide-free surfaces are required for leak-free joints.

Key Features

• Stainless steel bristles resist corrosion and hold up to refrigeration oils and flux residues
• Hex shaft stem accepts standard drill chucks for power-driven operation
• 0.25-inch inside diameter fits common small-bore refrigeration fittings
• 0.4375-inch actual brush diameter provides consistent contact across the fitting surface
• 3.125-inch overall length gives clearance for most hand drill and right-angle applications
• Sold individually — no minimum quantity beyond one unit

Compatibility

Designed for use on 0.375-inch outside diameter refrigeration fittings and tubing connections typical in small-bore HVAC and refrigeration applications.

Installation Notes

HVAC and refrigeration technicians install and use this brush as part of fitting preparation before brazing or flaring. Always depressurize and isolate the refrigerant circuit before working on any fittings or tubing. Chuck the hex shaft securely into a variable-speed drill and run at moderate speed to avoid flaring the bristles or damaging soft copper fitting surfaces. Wear appropriate eye protection when operating any rotary wire brush tool.
