How is a reducing tee ordered?

A reducing tee is a type of pipe fitting used to connect three different pipe sizes, allowing for a change in diameter. The proper way to order a reducing tee is by specifying the sizes of the two ends and the center connection. The ordering convention for reducing tees starts with the sizes of the two end connections, followed by the size of the center connection.

In this case, ordering the tee as "End x end x center" ensures that the supplier clearly understands the configuration of the fitting. This ordering involves listing the sizes of the two openings at the ends of the tee first, which is typically of equal size or larger, and then detailing the size of the center connection that is either smaller or different. This convention is essential for ensuring that the correct fitting is manufactured or supplied, making it functional for the intended plumbing or piping application.

Other options do not follow the widely accepted standards for describing reducing tees. Therefore, using "End x end x center" for ordering correctly communicates the required fitting dimensions and ensures compatibility with existing piping systems.
