A.Y. McDonald 74760-22 1" x 3/4" Tee Fitting, Series 5140-123

The A.Y. McDonald 74760-22 is a 1" x 3/4" reducing tee fitting from the 5140-123 series, designed for use in behind-the-wall and underground water service piping runs where a branch connection needs to be taken off a main line. This fitting allows a plumber or contractor to split a 1" supply line down to a 3/4" branch without re-piping the entire run, keeping rough-in layouts flexible on both new construction and retrofit jobs. As with all A.Y. McDonald water works fittings, the 74760-22 is built to standard trade dimensions so it can be specified with confidence against manufacturer part number 74760-22 and series designation 5140-123.

Key Features

  • Trade Size: 1" x 3/4" reducing configuration for splitting a 1" main into a 3/4" branch line.
  • Tee Configuration: Three-way fitting layout allows a branch takeoff from an existing water service run without cutting in a full reducer and coupling assembly.
  • Manufacturer Part Number: Identified by A.Y. McDonald as part 74760-22, series 5140-123, for accurate cross-reference and reordering.
  • Rough-In Application: Suited to installation behind walls, below grade, or in mechanical rooms as part of a water distribution or service line assembly.
  • Trade-Standard Fit: Sized to standard nominal pipe dimensions so it integrates with existing 1" and 3/4" piping runs on the job.

Technical Specifications

  • Trade Size: 1" x 3/4"

A.Y. McDonald 74760-22-1X3/4 – Frequently Asked Questions

1) What size pipe does the A.Y. McDonald 74760-22 tee connect?
It's a 1 inch x 3/4 inch reducing tee, so the run is 1 inch and the branch takeoff is 3/4 inch. That's the configuration you want when you need to pull a 3/4 inch branch off a 1 inch water service line without re-piping the whole run.
2) Is the 74760-22 a reducing tee or a straight tee?
Reducing. The 74760-22 in A.Y. McDonald's 5140-123 series is a three-way fitting with the branch reduced to 3/4 inch off a 1 inch main. If all three of your openings are the same size, this is the wrong fitting, you want a full-size 1 inch tee instead.
3) Will this tee fit my existing 1 inch and 3/4 inch pipe runs?
It's sized to standard nominal trade dimensions for 1 inch and 3/4 inch pipe, so it integrates with existing runs at those sizes. Nominal 1 inch and 3/4 inch are the two most common residential and light commercial water service sizes, which is why this reducing combination is the one most often stocked.
4) Can I use this A.Y. McDonald tee on a buried water service line?
Yes. The 74760-22 is intended for water service piping, including below grade runs, behind-the-wall rough-in, and mechanical room distribution assemblies. It's commonly used for branch connections on new construction and on service line repairs.
5) What part number and series do I quote to reorder this A.Y. McDonald tee?
Order it as A.Y. McDonald part number 74760-22, series 5140-123, in the 1 inch x 3/4 inch size. Those three together identify the fitting for cross-reference and repeat orders.
6) Do I still need a reducer and coupling if I use the 74760-22?
No. The point of the reducing tee is that the size change happens in the fitting itself, so you don't have to cut in a full-size tee plus a reducer and coupling to get down to a 3/4 inch branch. One fitting, three connections, fewer joints to leak.
