Schaefer Brush 08543-12 Power Fitting Cleaning Brush

Product Description

The SCHAEFER BRUSH 08543-12 is a twisted wire stem power fitting and cleaning brush designed for deburring, cleaning, and preparing tubing fittings in refrigeration and HVAC applications. Built with carbon steel bristles, it features a 1/8 inch inside diameter, a 5/16 inch actual brush diameter, and an overall length of 3-5/8 inches. The 1/8 inch shank diameter allows it to be chucked into a power drill or used with a hand driver. This brush is a standard tool for HVAC and refrigeration technicians who need consistent, repeatable fitting prep before brazing or flaring connections.

This brush is suited for residential and light commercial HVAC and refrigeration work. It is commonly used to clean the inside of 1/4 inch refrigeration fittings and tubing ends prior to assembly. The twisted wire stem construction holds bristle integrity under power rotation, making it reliable for repeated use in the field or on the bench. Technicians working on copper tubing systems, split systems, and refrigerant line sets will find this brush appropriate for standard connection prep tasks.

Installation Notes

This brush is typically used by HVAC and refrigeration technicians during system installation or service. Always isolate and recover refrigerant from any system section being serviced before cleaning fittings. When using this brush with a power drill, operate at a controlled speed to avoid bristle flare or damage to soft fittings. Inspect the brush for worn or splayed bristles before each use and replace when cleaning performance degrades.
