General Wire Spring ck-12 Copper Tube Fitting Prep Tool

Product Description

The GENERAL WIRE SPRING ck-12 is a copper tube fitting preparation tool designed to clean and prep 1/2 inch copper tubing ends for soldered or press fittings. Known as the CopperKey, this tool combines the functions of a tube reamer, fitting brush, and outside deburring tool into a single compact unit. It is built for plumbers and pipe fitters who need a fast, consistent prep on copper tube before making a joint. The ck-12 removes burrs, cleans the tube OD, and brushes the fitting socket in one pass, reducing prep time on the job.

The ck-12 is suited for residential and light commercial plumbing work where 1/2 inch copper pipe is common. Typical applications include domestic water supply lines, hydronic heating loops, and refrigeration copper tubing that requires a clean, oxide-free surface before soldering or pressing. It is a hand tool that fits easily in a tool pouch, making it practical for service calls and new construction alike.
