The MUELLER INDUSTRIES W1025 is a copper sweat coupling that connects two copper pipes of different sizes. It links a five-eighth inch pipe to a three-eighth inch pipe in plumbing or HVAC applications. This coupling uses a sweat connection method, which means it is soldered to the copper pipes to create a reliable and sealed joint.
This coupling is practical for achieving secure connections in plumbing configurations where size differences occur.
