Choosing Plumbing

How do I choose plumbing tools?

Match the tool to the pipe material and joint — tubing cutters for clean square cuts on copper and plastic, internal wrenches for recessed fittings and slip nuts, and crimp or clamp tools for PEX and push-to-connect systems. A tool that fits the specific fitting prevents leaks and damaged connections.
