A.Y. McDonald 5140-018 – Frequently Asked Questions

1) Is the A.Y. McDonald 5140-018 a straight coupling or a reducing coupling?
It is a reducing coupling. The 5140-018 is listed as a 1 x 1 1/2 coupling, so the two CTS ends are different sizes and it transitions between them in one fitting instead of needing a coupling plus a bushing.
2) What part number do I order for the A.Y. McDonald 1 x 1-1/2 CTS coupling?
Order A.Y. McDonald model 5140-018. That is the manufacturer part number for the no-lead CTS x CTS coupling in the 1 x 1 1/2 size, and it is the only configuration this model covers, so there is no size or finish option to specify with it.
3) Can a plumber use this A.Y. McDonald coupling on a potable water service line?
Yes, that is what it is built for. It is a no-lead brass coupling with copper tube size connections on both ends, the standard joint for underground water service between the main and the building. For a property manager or utility crew standardizing on one supplier, the A.Y. McDonald water service line covers curb stops, corporation stops and couplings on the same CTS connections.
