Oatey PP8555 Inside Cleaning Brush 3/4 Inch Copper

Product Description

The OATEY PP8555 is a 3/4-inch inside cleaning brush designed for preparing copper pipe fittings before soldering. The brush cleans the interior socket of copper fittings by removing oxidation, dirt, and surface contamination that would otherwise compromise solder joint integrity. Sold one brush per card, it is a standard tool in any plumber's prep kit when working with sweat-fit copper connections. Proper cleaning of both the pipe OD and fitting ID is a fundamental step in producing leak-free solder joints that meet plumbing code requirements.

This brush is used in residential and light commercial plumbing applications wherever 3/4-inch copper pipe and fittings are joined by soldering. Plumbers, pipefitters, and experienced DIYers use inside cleaning brushes during new installation and repair work on water supply lines, hydronic heating systems, and other copper piping systems. It is part of a standard fitting-prep workflow alongside outside diameter brushes and flux.

Installation Notes

Shut off and drain the water supply before beginning any soldering work on copper pipe. Insert the brush into the fitting socket and rotate to abrade the interior surface until the socket is clean and bright. Follow all applicable local plumbing codes and IFGC or IPC guidelines for soldered connections. Soldering of potable water lines must use lead-free solder and flux as required by code.
