A.Y. McDonald 5121-150 1" Quarter Bend Flare x Flare Fitting, No-Lead

The A.Y. McDonald 5121-150 (mfr. part 74761) is a 1" Quarter Bend fitting configured Flare x Flare, engineered as a No-Lead (NL) product for potable water service. This 90-degree bend allows plumbing and water-service installers to change the direction of a flared copper or tubing run without cutting additional straight sections, keeping joints clean and leak-resistant. As a No-Lead fitting, the 5121-150 is manufactured to meet low-lead content requirements for water-carrying applications, making it a dependable choice for residential and light commercial water service lines where compliance with lead-free plumbing standards is required. A.Y. McDonald is a long-established name in waterworks and plumbing fittings, and this Quarter Bend continues that reputation for precision-machined, code-focused components that fit standard flare tubing connections without adapters. The Flare x Flare configuration on both ends means the fitting mates directly with standard flare nuts and flared tubing ends, simplifying installation for plumbers, contractors, and utility crews working on water service lines, meter setters, and other flared-tubing assemblies. Whether used in new construction or repair/retrofit work, this quarter bend provides a compact, reliable way to route flared tubing around obstacles or into risers while maintaining the No-Lead standard required on potable water systems. Installers appreciate that no additional adapters or transition fittings are needed since both ends of the 5121-150 accept standard flare nuts directly, reducing the number of joints in a run and, by extension, the number of potential leak points on a completed water service installation.

A.Y. McDonald 5120-146 – Frequently Asked Questions

1) Can this A.Y. McDonald quarter bend be used on a potable water service line?
Yes. The quarter bend is a No-Lead (NL) brass fitting made for potable water service, which is what water service lines, meter setter assemblies and risers require. It is used in both residential and light commercial water service work.
2) Do I need adapters or a flare nut kit to install this quarter bend?
No adapters. Both ends are flare, so the elbow mates directly to standard flare nuts on flared copper or tubing ends. You supply the flare nuts and the properly flared tube ends; the fitting itself does not include them.
3) Will a flare x flare elbow work on a compression or pack joint water service connection?
No. This is flare on both ends, which means it only mates with flared tubing and flare nuts. Compression, pack joint and CTS grip connections are a different end prep entirely and will not seal against a flare seat. If your existing service uses pack joint fittings, you need a pack joint elbow or a flare-to-pack-joint adapter instead.
4) Is a quarter bend the right fitting for a 90 degree turn on a flared copper service line, or should I use a coupling and bent tubing?
A quarter bend gives you the full 90 degree direction change in one fitting, so you avoid cutting in extra straight sections or couplings to route around an obstacle or turn up into a riser. Fewer joints means fewer places a service line can weep. Bending the soft copper yourself works where you have the radius room; in a tight meter pit or against a foundation wall, the quarter bend is what fits.
5) What is A.Y. McDonald part 74761?
74761 is the manufacturer part reference cross-referenced to the 5121-150, the 1 inch No-Lead quarter bend with flare connections on both ends. If your takeoff or counter ticket lists 74761, the 1 inch size is what you want.
