A.Y. McDonald 5121-149 – Frequently Asked Questions
1) What connection type does the A.Y. McDonald 5121-149 tee use on all three ports?
All three ports on the A.Y. McDonald 5121-149 tee are flare, so it is a flare x flare x flare fitting. That means it mates to flared copper or plastic tubing with flare nuts on every branch, and it will not thread onto pipe threads or accept a compression or solder joint without an adapter.
2) Is the A.Y. McDonald 5121-149 tee lead free for potable water service?
The 5121-149 carries the NL designation, A.Y. McDonald's no-lead marking, which is what water utilities and plumbing inspectors look for on a potable water service fitting. The tee is model 5121-149, factory number 74760.
3) What size tubing does the A.Y. McDonald 74760 flare tee fit?
The 74760 tee is a 1 inch fitting on all three flare ports, so it branches a 1 inch service line without a reducer. Order the number as 5121-149.
4) Should I use a flare tee or a compression tee on a copper water service line?
A flare tee like the A.Y. McDonald 5121-149 needs the tube end flared with a flaring tool, and the flare nut pulls the cone tight against the fitting seat, which is the joint most water departments accept on buried copper service. A compression style tee installs without flaring but relies on a gasket or grip ring. If the utility spec on your job calls out flare, the flare x flare x flare 5121-149 is the fitting that matches it.
5) Do I need to buy flare nuts separately for the A.Y. McDonald 5121-149 tee?
The 5121-149 is a single tee body with three flare ends. The tubing side of a flare joint is made up with a flare nut on each tube, so plan on three nuts sized to the 1 inch tubing plus a flaring tool to form the tube ends before the fitting goes in.
6) Is the A.Y. McDonald 5121-149 a pipe fitting or a valve?
It is a tee, a three way branch fitting with no shutoff of any kind. If you need to branch a 1 inch service and also isolate it, you will need a separate curb stop or corporation valve in the run.
7) Are there different sizes or configurations of the A.Y. McDonald 74760 tee to choose from?
There is one configuration: model 5121-149, the 1 inch flare by flare by flare no-lead tee. Nothing to specify beyond the model number when you order.
