A.Y. McDonald 5182-022 3/4" No-Lead CTS x MNPT Quarter Bend

The A.Y. McDonald 5182-022 is a 3/4" quarter bend fitting designed for rough-in plumbing installations where a copper tube size (CTS) connection needs to transition into a male national pipe thread (MNPT) connection at a 90° angle. Identified in the manufacturer catalog as part number 74779MQ, this fitting carries a No-Lead (NL) designation, making it suitable for potable water applications where lead-free components are required by the installing contractor or local plumbing code. As a quarter bend, this fitting turns the direction of a water line by 90°, allowing plumbers to route CTS tubing runs into threaded fixture connections, valves, or other MNPT-equipped components without needing a separate coupling or adapter piece. This type of transition fitting is a common requirement behind walls, under floors, and inside mechanical rooms where copper tube sized lines need to terminate into a threaded outlet.

Key Features

  • Trade Size: 3/4" CTS x MNPT, sized to connect copper tube size tubing runs to a 3/4" male threaded outlet.
  • Configuration: Quarter bend (90°) design changes the direction of the water line by a quarter turn, eliminating the need for a separate elbow and adapter combination.
  • Dual-End Connection: One end is sized for CTS (copper tube size) tubing while the opposite end terminates in male national pipe threads (MNPT) for connection into threaded valves, stops, or fixture supply points.
  • No-Lead Compliance: Manufactured to a No-Lead (NL) specification as noted in the part designation, supporting use in potable water supply lines where lead-free fittings are specified.
  • Rough-In Application: Built for behind-the-wall and under-floor plumbing work where a direct, single-piece transition and directional change is needed in one fitting.
  • Manufacturer Part Cross-Reference: Cataloged under both the A.Y. McDonald 5182-022 model number and the 74779MQ reference number for identification during ordering and inventory management.

Technical Specifications

  • Trade Size: 3/4"
  • Connection Type: CTS x MNPT
  • Angle: 90° (Quarter Bend)
  • Compliance: No-Lead (NL)

A.Y. McDonald 5182-022 – Frequently Asked Questions

1) What does CTS x MNPT mean on the A.Y. McDonald 5182-022 quarter bend?
One end of the 5182-022 is sized for copper tube size (CTS) tubing, the other end is male national pipe thread. So the CTS end goes onto your 3/4 inch copper tube sized water line and the threaded end screws into a female threaded valve, stop, or fixture supply point. Both ends are 3/4 inch.
2) Is the A.Y. McDonald 5182-022 quarter bend safe for potable water?
It carries the No-Lead (NL) designation, which is why it gets specified on potable water supply lines where lead-free fittings are required. That is the compliance marking A.Y. McDonald publishes for this fitting.
3) Will a 3/4 inch CTS fitting work on 3/4 inch nominal copper pipe?
Yes, for water tube. Copper tube size means the fitting is made to the outside diameter of 3/4 inch copper water tube, which is 7/8 inch OD, so nominal 3/4 inch type K, L, or M tube is what this end is sized around. If your line is 3/4 inch iron pipe size, that is a different diameter and this CTS end will not take it.
4) Do I still need an elbow and a separate adapter if I use this fitting?
No. The 5182-022 makes the 90 degree turn and the CTS-to-threaded transition in one body, so you are not stacking an elbow plus an adapter or coupling at that point. Fewer joints behind the wall.
5) Is 74779MQ the same part as the A.Y. McDonald 5182-022?
Yes, same fitting. A.Y. McDonald catalogs it as model 5182-022 and cross-references it as 74779MQ, so either number identifies the 3/4 inch No-Lead CTS x MNPT quarter bend.
6) Can I thread this into a male threaded valve?
No. The threaded end of the 5182-022 is male NPT, so it needs a female threaded port. If the component you are tying into is also male, you need a female-to-female coupling between them, or a different fitting configuration.
7) Where in a job does a quarter bend like this actually get used?
Rough-in work, mostly out of sight: behind walls, under floors, and in mechanical rooms where a CTS tubing run has to change direction 90 degrees and terminate into a threaded outlet. Typical spots are feeding a threaded stop or valve, or bringing a supply up to a fixture connection on new construction and remodel work.
