How to Remove a Compression Ring From a Copper Pipe

A compression ring fits on the end of a copper pipe and is an essential part of a compression fitting. Compression is a method for connecting plumbing fittings without soldering. A nut is placed on the pipe with the threads pointing toward the end and a small brass ring is fitted on the end of the pipe. When the nut is threaded onto the fitting, it traps the compression ring between it and the fitting. A watertight seal is formed when the nut is tightened. You can remove a compression ring from a copper pipe following a straightforward procedure.

Step 1

Spray the compression ring with a penetrating catalyst. Spray the catalyst on both sides of the ring around the entire circumference. A penetrating catalyst is a petroleum-based product that helps loosen fittings and screws. Let the catalyst soak into the ring for 15 minutes.

Step 2

Grasp the ring with a pair of slip-joint pliers and turn it one way then the other. Use short powerful bursts to break the ring free.

Step 3

Pull the ring forward toward the end of the pipe once you are able to get it to turn on the pipe. Move the ring back and forth on the pipe as you pull it forward until it is completely detached from the pipe.
