The Waterway 400-5570 union assembly includes a 2 inch union nut with a 2 inch slip tailpiece and O-ring. This coordinated replacement is useful because it refreshes several of the most important parts of the union connection at once, helping reduce the chance of mismatch during repair.

Including the O-ring makes the assembly especially practical when sealing performance also needs attention, not just the hard plumbing pieces. This Waterway union set is a smart choice when the original connection is worn, leaking, or no longer dependable across multiple components.

For compatible plumbing service and rebuild work, this Waterway union assembly is a practical solution when the 2 inch nut, tailpiece, and sealing element all need to be renewed together.
