A.Y. McDonald 5182-013 3/4" CTS x MNPT No-Lead Adapter Fitting

The A.Y. McDonald 5182-013 (also referenced as 74753Q) is a 3/4" CTS x MNPT adapter fitting built for rough-in water service connections. This transition fitting converts copper tube size (CTS) compression or push-fit tubing to male national pipe thread (MNPT), giving plumbers and contractors a reliable way to join CTS-sized tubing runs to threaded valves, meters, or fittings on the pressure side of a water system. As a no-lead (NL) fitting, it is manufactured to meet low-lead content requirements for potable water service applications. This adapter is a behind-the-wall or underground rough-in component and is intended for installation by licensed trade professionals, not a decorative or exposed fixture.

Key Features

  • Trade Size: 3/4" CTS (copper tube size) connection sized for standard 3/4" CTS tubing runs.
  • Adapter Configuration: CTS x MNPT design transitions CTS-sized tubing to male national pipe thread (MNPT) for connection to threaded fittings, valves, or meter connections.
  • No-Lead Construction: Manufactured as an NL (no-lead) fitting for use in potable water applications where low-lead content is required.
  • Model Reference: Also cataloged under item number 74753Q for cross-reference with A.Y. McDonald distributor part numbering.
  • Rough-In Application: Designed for installation on water service lines, meter setters, and underground or wall-concealed plumbing connections.

A.Y. McDonald 5182-013 – Frequently Asked Questions

1) Is the A.Y. McDonald 5182 adapter safe for potable water lines?
It is a no-lead (NL) fitting, made for potable water service where low-lead content is required. That is what makes it usable on water service line rough-in, meter setters, and concealed potable connections rather than non-potable work only.
2) What does CTS x MNPT actually mean on this fitting, and what does it connect to?
CTS is copper tube size, the sizing convention used for water service tubing; MNPT is male national pipe thread. So one end takes 3/4 inch CTS tubing and the other threads into a female NPT port, a threaded valve, a meter connection, or a threaded fitting. It is a transition piece, not a coupling of two like ends.
3) I need to tie 3/4 inch CTS poly or copper tubing into a threaded meter setter. Is this the right part?
Yes, that is exactly the job the 5182-013 is built for. It converts a 3/4 inch CTS tubing run to male NPT so it threads straight into the setter or meter connection, instead of stacking two or three fittings to get there. It is a rough-in component for service lines, underground or behind the wall.
4) Is the A.Y. McDonald 5182 an exposed trim fitting I can use under a sink?
No. This is a behind-the-wall or underground rough-in fitting for water service work, meant to be installed by licensed trade professionals. It is not a decorative or exposed fixture fitting, so if you need a visible supply connection, look at finished trim rather than a service-line adapter.
5) Which 5182 do I order if my tubing is 1 inch but the threaded side is 3/4 inch?
Order 5182-003, the 1 inch x 3/4 inch version. The straight 3/4 inch 5182-013 will not bridge a size change. Confirm which end of your run is the larger size before writing the order, since a reducing adapter only works one way round.
6) Does the 5182 adapter come with a gasket, nut, or insert stiffener?
The 5182 is sold as the adapter fitting itself. Nothing beyond the fitting is listed as included, so plan on supplying any tubing insert stiffener, thread sealant, or tape your installation calls for separately.
