A.Y. McDonald 5131-066 – Frequently Asked Questions

1) What size pipe does the A.Y. McDonald 5131-066 coupling join?
The 5131-066 is a reducing coupling that joins 1-1/2 inch to 2 inch CTS on both ends, so it transitions between those two copper tube sizes in a single fitting. Order it as model 5131-066.
2) What does CTS x CTS mean on this A.Y. McDonald coupling?
Both ends are sized to CTS, copper tube size, rather than IPS. That matters because CTS and IPS outside diameters are not the same at a given nominal size, so a CTS x CTS fitting mates to copper tube size pipe on both sides. If one side of your run is IPS, this coupling is the wrong fitting and you need a CTS x IPS transition instead.
3) Is the A.Y. McDonald 5131-066 coupling lead free for potable water?
The 5131-066 carries the NL designation, A.Y. McDonald's no-lead marking, which is what buyers specify for potable water service work.
4) What is the manufacturer part number for the A.Y. McDonald 1-1/2 x 2 CTS coupling?
The manufacturer part number is 5131-066, the reference on the fitting itself is 74758-22, and it is sold as a single model with no finish or option choices to specify.
5) Can I use the 5131-066 on a buried water service line?
It is a service-line style coupling for copper tube size pipe, and the two ends are 1-1/2 inch and 2 inch CTS. Confirm your run is CTS on both sides and that the joint method matches the fitting you are ordering before you set it in the trench.
