A.Y. McDonald 5130-003 – Frequently Asked Questions
1) What does CTS x IPS mean on the A.Y. McDonald 5130-003 coupling?
It means the two ends are sized to different pipe standards. One end takes 1 inch CTS (copper tube size, which is what soft copper water service tubing and CTS-sized plastic service pipe measure), and the other takes 1 inch IPS (iron pipe size, the standard for galvanized steel and IPS-dimensioned plastic pipe). Same nominal 1 inch call-out on both ends, but the actual outside diameters differ, which is exactly why a transition coupling is needed rather than a straight coupling.
2) I'm running a new 1 inch water service and need to tie copper tubing into existing IPS pipe. Is this the right fitting?
That is the job this fitting is built for. The A.Y. McDonald 5130-003 is a 1 inch CTS by IPS coupling, so it joins a 1 inch copper-tube-size run to a 1 inch iron-pipe-size run in a single fitting. If both sides of your connection are the same standard, you do not want this one, you want a straight CTS x CTS or IPS x IPS coupling instead.
3) What part number should I give my supplier for the A.Y. McDonald 1 inch CTS x IPS coupling?
Order it as A.Y. McDonald 5130-003. The same item also shows under the manufacturer reference 74758-22-55. Quoting 5130-003 is the cleanest way to make sure you get the 1 inch CTS by IPS configuration and not a same-size straight coupling.
