The Waterway 400-4030 union assembly is designed for compatible plumbing applications using a 1-1/2 inch slip connection and a 1-1/2 inch male pipe thread outlet. This type of union is useful where the line needs to stay serviceable while bridging rigid plumbing and a male-threaded connection in the same assembly.

That format can be especially practical in equipment pads and retrofit situations where one side of the line already depends on threaded plumbing. Choosing the correct Waterway union helps keep the connection cleaner and easier to service in the future.

For compatible plumbing repairs and installations, this Waterway union assembly is a practical option when a 1-1/2 inch slip-to-male-thread serviceable connection is needed.

  • Waterway union assembly
  • 1-1/2 inch slip x 1-1/2 inch male pipe thread connection
  • Useful for mixed rigid and threaded plumbing systems
  • Helps preserve service access in the line
  • Supports cleaner and more dependable installation
