A.Y. McDonald 708U2M U-Branch Fitting, CTS x MNPT, No-Lead Brass, 1" x 3/4" x 7.5"
The A.Y. McDonald 708U2M is a No-Lead brass U-Branch fitting built for rough-in water service work where a single supply line needs to split into two independent outlets. Configured as 1" x 3/4" x 7.5", this U-Branch transitions from CTS (copper tube size) on the inlet to MNPT (male national pipe thread) on the branch connections, giving plumbers a reliable way to tie into copper tubing while stepping down to threaded connections for meter setters, service branches, or dual-service installations. Manufactured to No-Lead standards, the 708U2M is suited for potable water rough-in applications where lead-free brass construction is required.
Key Features
- Trade Size: 1" x 3/4" x 7.5" configuration sized for service-line branching and dual-outlet rough-in runs.
- U-Branch Design: Splits a single inlet into two separately threaded outlets for parallel service or metering setups.
- CTS x MNPT Connection: Copper tube size inlet mates directly to copper tubing, while male national pipe threads on the branch outlets connect to standard threaded fittings, valves, or meter equipment.

- Model 708U2M: Part of A.Y. McDonald's 708U2M series of U-Branch waterworks fittings, identified by manufacturer designator 5141127.

A.Y. McDonald 5141127 – Frequently Asked Questions
1) What does the A.Y. McDonald 708U2M U-branch actually do on a water service?
The 708U2M U-branch takes one incoming service line and splits it into two independent threaded outlets, so two meters or two services can run off a single tap. Inlet is CTS (copper tube size) and the branch outlets are MNPT, so you solder or compress onto copper tubing coming in and thread valves, meter setters, or service branches onto the outlets.
2) What size connections does the A.Y. McDonald 5141127 U-branch have?
It is the 1" x 3/4" x 7.5" configuration: a 1 inch CTS inlet, 3/4 inch MNPT branch outlets, with 7.5 inches across the branch spread. If your two outlets need to land on a different center spacing, or you are running 3/4 inch copper into the tap, this is the wrong size and you want another configuration in the 708U2M range.
3) Is the 708U2M U-branch fitting lead free for potable water?
Yes. The 5141127 is built to No-Lead specification in brass, which is what a potable water rough-in requires on municipal and residential service work. That covers both the inlet and the threaded branch outlets, so the whole body is in the potable stream legitimately.
4) Can I use a U-branch instead of running two separate taps for a duplex?
That is exactly what a U-branch is for. Rather than cutting two corporation stops into the main, the 708U2M lets one 1 inch CTS service feed two 3/4 inch MNPT outlets, each of which can carry its own meter and shutoff. It is common on dual-meter and dual-service installs, underground or behind the wall. If the two units need fully separate service lines from the main for code or billing reasons in your jurisdiction, a U-branch will not satisfy that.
5) What thread type are the outlets on the A.Y. McDonald 708U2M, and what mates to them?
Both branch outlets are MNPT, male national pipe thread. They take any standard female NPT connection: angle meter valves, ball valve curb stops with FIP inlets, meter setters, or a female adapter into whatever you are running downstream. You will need thread sealant or tape; nothing is supplied on the fitting.
6) Does the CTS inlet on this U-branch fit standard copper water tubing?
Yes, the inlet is sized to CTS, copper tube size, so it lands on nominal 1 inch copper service tubing directly. Note CTS is not the same nominal reference as iron pipe size, so if your service line is 1 inch IPS plastic or steel you need a different inlet style, not this one.
7) What is the manufacturer part number for the 1 x 3/4 x 7.5 inch A.Y. McDonald U-branch?
Order it as A.Y. McDonald 5141127, model 708U2M. That number pins the exact 1" x 3/4" x 7.5" CTS x MNPT No-Lead brass configuration, which matters because the 708U2M designation covers several sizes.
8) Can the 708U2M U-branch be buried in a direct-bury service trench?
It is made for underground and behind-the-wall rough-in, and the No-Lead brass body is the standard material for buried waterworks service fittings. Keep the MNPT joints properly made up and supported, since a threaded joint in a trench is the point that moves if the bedding settles.
