Schaefer Brush 08749-12 Fitting Cleaning Brush 1 in Id

Product Description

The SCHAEFER BRUSH 08749-12 is a stainless steel power fitting and cleaning brush designed for deburring, cleaning, and preparing pipe fittings and tubing connections. It features a 1 inch inside diameter with a 1-3/16 inch actual brush diameter, making it well-suited for cleaning the interior surfaces of fittings in HVAC and refrigeration applications. The brush rides on a twisted wire stem with a 3/16 inch shank diameter for use with a power drill or rotary tool. At 3-5/8 inches in overall length, it reaches into standard fittings without interference. The stainless steel bristles resist corrosion and hold up to repeated use on copper, brass, and similar fitting materials.

This brush is used by HVAC technicians and refrigeration mechanics when prepping fittings and tubing ends before brazing or soldering. It removes oxidation, flux residue, and light corrosion from fitting interiors quickly and consistently. The 3/16 inch shank fits standard drill chucks, making it straightforward to incorporate into a typical service workflow. It is also noted for a 1-1/8 inch refrigeration outside diameter, which corresponds to common refrigeration line fitting sizes found in residential and light commercial systems.

Installation Notes

Installation is performed by HVAC technicians and refrigeration mechanics. Ensure the system is recovered, depressurized, and de-energized before cleaning any fittings or tubing connections. Chuck the 3/16 inch shank securely in a power drill or rotary tool before use. Do not exceed the rated speed of the tool or apply excessive side-loading pressure, which can distort the twisted wire stem.
