A.Y. McDonald 5140-106 3/4" CTS x MIP Coupling Fitting

The A.Y. McDonald 5140-106 is a 3/4" CTS Joint x MIP coupling engineered to transition CTS (Copper Tube Size) tubing to a male iron pipe (MIP) threaded connection. Cross-referenced in manufacturer documentation as the 74753-22 CTS Joint x MIP Coup, this fitting gives water service installers a dependable, single-body solution for joining CTS-sized tubing directly to threaded pipe, valves, or fittings. Built to A.Y. McDonald's manufacturing standards for water works products, the 5140-106 is designed for secure, long-term performance in underground and above-grade water service and distribution applications where a CTS-to-threaded-pipe transition is required.

Key Features

  • Trade Size: 3/4" sizing for direct compatibility with standard 3/4" CTS tubing runs.
  • CTS Joint Connection: One end is configured for CTS (Copper Tube Size) joint connection, allowing a direct, secure coupling to CTS-sized tubing without additional adapters.
  • MIP Threaded Connection: The opposite end features a Male Iron Pipe (MIP) thread, enabling straightforward connection to female-threaded pipe, valves, meters, or other threaded fittings.
  • Model Reference: Identified by manufacturer part number 74753-22, cross-referenced to A.Y. McDonald catalog number 5140-106 for easy ordering and documentation lookup.
  • Coupling Configuration: Functions as a transition coupling, bridging two differing pipe/tubing connection types in a single fitting body to simplify installation and reduce joint count.
  • Manufacturer-Documented: Full dimensional and material specifications are available via A.Y. McDonald's published spec sheet for this exact part number.

A.Y. McDonald 5140-106 – Frequently Asked Questions

1) What does the A.Y. McDonald 5140-106 coupling connect to?
It's a 3/4 inch coupling with a CTS compression joint on one end and a male iron pipe (MIP) thread on the other. So one side grips 3/4 inch copper tube size poly or copper service pipe, and the other threads into a 3/4 inch female NPT fitting, valve, or meter setter. Both ends are 3/4 inch, so it is not a reducer.
2) Will the 5140-106 work on 3/4 inch poly water service pipe?
Yes, provided the pipe is 3/4 inch CTS (copper tube size) poly. The compression joint on this A.Y. McDonald coupling is sized for CTS outside diameter, which is what municipal water service poly tubing uses. If your pipe is 3/4 inch IPS-size poly, the OD is different and this joint will not seal on it.
3) Do I need anything else to install the 5140-106 coupling?
The compression side needs no separate kit, but insert-type poly pipe generally requires a stiffener inside the tubing at the joint, and the MIP thread needs thread sealant or PTFE tape rated for potable water. Nothing beyond the coupling itself is described as included.
4) What is the exact part number to order this A.Y. McDonald coupling?
Order A.Y. McDonald model 5140-106, the 3/4 inch CTS joint by MIP coupling. A.Y. McDonald also references it as 74753-22.
5) Can I use the 5140-106 to transition from copper service line to a threaded meter setter or curb stop?
That is exactly the use. The MIP end threads directly into a 3/4 inch female-threaded meter setter, curb stop, or yoke, and the CTS compression end takes the 3/4 inch service tubing, so you make the transition in one fitting without a union or adapter pair.
