A.Y. McDonald 5119-138 CTS x CTS x FNPT Reducing Tee, Lead-Free

The A.Y. McDonald 5119-138 (model 74764-22) is a 2x1 reducing tee fitting configured CTS x CTS x FNPT, designed for potable water service line and distribution connections. This lead-free (NL) fitting provides a reliable branch connection point where a CTS run transitions to a female national pipe thread (FNPT) outlet, making it a practical choice for water utility and plumbing contractor applications requiring code-compliant, lead-free materials. As part of A.Y. McDonald's waterworks fitting line, the 5119-138 is built to the dimensional and thread standards required for CTS (Copper Tube Size) compression connections paired with a threaded FNPT branch. This 2x1 sizing allows installers to step down at the branch outlet, simplifying tie-ins where a smaller threaded connection is required off a larger CTS distribution run, and the lead-free construction ensures the fitting meets requirements for potable water contact.

Key Features

  • Configuration: 2x1 tee design with CTS x CTS x FNPT connections for flexible branch installations.
  • Connection Type: CTS (Copper Tube Size) inlet/outlet ends paired with a female national pipe thread (FNPT) branch outlet.
  • Lead-Free Compliant: Manufactured to NL (No Lead) specifications for potable water service in compliance with applicable lead-free plumbing requirements.
  • Model Reference: Cross-referenced as A.Y. McDonald 74764-22, ensuring accurate identification for replacement and specification matching.
  • Reducing Tee Function: Sized 2x1, allowing a size transition at the branch connection for service line tie-ins.
  • Branch Outlet Design: FNPT threaded branch enables direct connection to standard male-threaded components without additional adapters.

A.Y. McDonald 5119-138 – Frequently Asked Questions

1) What do the CTS x CTS x FNPT ends on the A.Y. McDonald 5119-138 tee connect to?
The 5119-138 is a branch tee with two CTS (copper tube size) ends and one female NPT tapped outlet. The CTS ends take copper tube size service line, and the FNPT outlet threads onto male pipe thread, so you can tap a threaded take-off, meter setter nipple, or valve off the run without adapting a compression end.
2) Is the A.Y. McDonald 5119-138 tee lead free for potable water service?
Yes. The 74764-22 tee carries the NL (no lead) designation, which is what you want on a potable water service line or meter setting. The lead-free suffix is part of the part identity, so a buyer specifying NL brass on a drinking water job is getting the right casting.
3) What size is the A.Y. McDonald 5119-138 branch tee?
It is a 2 x 1 tee: the CTS run is 2 inch copper tube size and the threaded branch is 1 inch female NPT. Use it where a 2 inch service needs a 1 inch threaded take-off, not where you need matching sizes on all three ports.
4) Can I use the A.Y. McDonald 5119-138 tee on PVC or PE pipe instead of copper?
The two straight ends on this tee are CTS, copper tube size, so they are sized for copper service tubing and CTS-dimensioned tube. Pipe sized to IPS dimensions, such as standard PVC or IPS polyethylene, will not land correctly in a CTS end. For an IPS service line you need an IPS-end fitting or an IPS-to-CTS transition ahead of the tee.
5) What part number do I order for a 2 inch by 1 inch no-lead branch tee from A.Y. McDonald?
Order A.Y. McDonald 5119-138, catalogued as 74764-22. That single number covers the 2 x 1 CTS x CTS x FNPT no-lead tee; there are no handing, finish, or option suffixes to specify with it.
6) Is the A.Y. McDonald 5119-138 a water service fitting or an electrical part?
It is a plumbing pipe fitting, a branch tee for water service line work, despite any electrical shelf code attached to it. Two CTS ends for copper service tube and a 1 inch female NPT branch, in no-lead brass.
