A.Y. McDonald 5141-156 – Frequently Asked Questions
1) Can I use a 1-1/4 CTS x FNPT adapter on 1-1/4 inch PVC or steel pipe instead of copper?
Not on the CTS side. CTS is sized to copper tube outside diameter, not iron pipe size, so 1-1/4 inch CTS will not mate with 1-1/4 inch IPS PVC or steel pipe. The FNPT side of the 5141-156 is standard pipe thread and will take a 1-1/4 inch MIP nipple of any material. If both sides of your run are IPS, you need an IPS x FNPT fitting, not this one.
2) Is the McDonald 5141-156 adapter lead free for potable water?
Yes. The NL suffix on the 5141-156 designates the no-lead brass version, which is what water utilities and plumbing inspectors require on potable water service lines.
3) What part number do I order for the 1-1/4 inch McDonald CTS to female pipe thread adapter?
Order A.Y. McDonald 5141-156. It is also referenced by the factory number 74754-22. Only the one model is offered, so there is no size or finish choice to specify.
4) Is this McDonald adapter a plumbing fitting or an electrical part?
It is a plumbing pipe fitting, a 1-1/4 inch CTS to female NPT adapter used on water service lines. Any electrical reference in the catalog data is a filing artifact, not a product function.
