Osborn 0007525500 Steel Tube End Fitting Brush

Product Description

The OSBORN 0007525500 is a steel tube end fitting brush designed for cleaning and deburring the interior ends of tubes and fittings. The brush measures 1 inch in brush length with a 57/64 inch brush diameter and an overall length of 6.375 inches, giving the technician solid reach into tight tube ends. Steel fill material and a 0.008 inch wire diameter provide consistent scrubbing action to remove scale, oxidation, and debris from metal tube bores. Plumbers, HVAC technicians, and pipe fitters keep this brush on hand for prep work before soldering, brazing, or mechanical joining of copper, steel, and similar tube stock.

This brush is suited for residential and light commercial service work where tube end cleanliness directly affects joint quality. It fits standard tube end and fitting bore prep tasks and is particularly useful when cleaning fittings before soldering copper lines or preparing steel tube ends prior to mechanical coupling. The 6.375 inch overall length allows controlled hand operation without requiring a power tool, making it practical for tight mechanical room installations and confined service areas.

Key Features

• 1 inch brush length sized for shallow tube end cleaning passes
• 57/64 inch brush diameter for snug fit inside standard tube bores
• 0.008 inch steel wire diameter delivers firm abrasive action on metal surfaces
• 6.375 inch overall length provides controlled reach without a power drive
• Steel fill material resists deformation during repeated use on hard tube stock

Compatibility

Designed as an OEM-style hand brush for tube end and fitting bore preparation on steel and compatible metal tube stock in plumbing and HVAC applications.

Installation Notes

A licensed plumber or HVAC technician should depressurize and drain the line before performing any tube end prep work. Insert the brush into the tube end or fitting bore and rotate with consistent hand pressure to remove scale and debris. Inspect the cleaned surface before proceeding with soldering, brazing, or mechanical joining. Follow applicable IPC and IFGC guidelines for joint preparation standards in your jurisdiction.
