4 in x 3 in ProPress Lead-Free Tube Fitting, Copper

This is the original press pipe joining system. Pressing pipe connections saves time and labor compared to traditional soldering, and offers more features and benefits than any other imitation press system. These press pipe reducers are suitable for plumbing applications with potable water. They crimp onto tubing and have a sealing O-ring to ensure a secure, leak-tight connection.
