The Waterco union adapter is designed for compatible plumbing applications that need to transition between a 1-1/2 inch barb connection and a 1-1/2 inch male pipe thread. An adapter like this is useful because it helps flexible hose and threaded plumbing components work together cleanly without forcing the installer to improvise around mismatched ends.

This part is especially useful where one side of the system depends on hose-style routing and the other side requires a threaded connection into a valve, fitting, or equipment body. Using the proper adapter helps keep the plumbing more serviceable and more intentional.

The WC122318P is a practical fitting when a compatible system needs a reliable union-style transition between barb and threaded connections.

  • Waterco union adapter
  • 1-1/2 inch barb by 1-1/2 inch MPT configuration
