A.Y. McDonald 4430-007 X-Riser Transition Fitting, 1-1/2" IPS x 1-1/2" MNPT, 36"

The A.Y. McDonald 4430-007 XR-31K-24-36-ZDC X-Riser is a zinc die cast transition fitting built for underground water service installations where SDR11 poly or PEX pipe needs to transition up to a threaded connection at grade. This riser is sized 1-1/2" IPS (SDR11/.173 wall) on the pipe-side connection and terminates in a 1-1/2" MNPT (male national pipe thread) fitting, with an overall length of 36". Rough-in plumbers and utility contractors use this fitting to carry a buried service line up through backfill to a meter, curb stop, or above-grade shutoff without requiring a field-fabricated riser assembly.

Key Features

  • Trade Size: 1-1/2" IPS pipe-side connection sized to SDR11/.173 wall poly or PEX tubing.
  • Threaded Outlet: 1-1/2" MNPT termination for connection to meter setters, curb stops, or above-grade valves and fittings.
  • Overall Length: 36" riser length, engineered to carry the service line from buried depth up to grade in a single fitting.
  • Durable Construction: Zinc die cast (ZDC) body for a rigid, corrosion-resistant transition point between flexible SDR11 pipe and rigid threaded hardware.
  • X-Riser Configuration: Purpose-built riser geometry (XR-31K-24-36-ZDC) designed specifically for SDR11-rated service line transitions rather than a generic coupling.
  • Simplified Rough-In: A single fitting replaces multiple field-cut and threaded joints when bringing a buried service line up to a meter or shutoff location.

Technical Specifications

  • Model: XR-31K-24-36-ZDC
  • Pipe-Side Connection: 1-1/2" IPS, SDR11/.173 wall
  • Threaded Connection: 1-1/2" MNPT
  • Length: 36"
  • Body Material: Zinc Die Cast (ZDC)

Typical Applications

  • Underground Water Service Line Installation
  • Meter Setter and Curb Stop Transitions
  • SDR11 Poly and PEX Pipe Riser Assemblies
  • Utility and Municipal Water Service Rough-In
  • New Construction and Service Line Replacement

Why A.Y. McDonald?

A.Y. McDonald builds waterworks and plumbing fittings engineered for the specific dimensional standards used in underground service line work, including SDR11 wall thickness and IPS sizing. The zinc die cast construction of the 4430-007 X-Riser is designed to hold up to the mechanical stress of a below-grade-to-above-grade transition, giving contractors a single reliable component instead of a multi-piece field assembly.

A.Y. McDonald 4430-007 – Frequently Asked Questions

1) Will the A.Y. McDonald 4430-007 X-Riser work with 1-1/2 inch SDR11 poly pipe?
Yes. The pipe-side connection on the 4430-007 is sized 1-1/2 inch IPS for SDR11 / .173 wall pipe, which covers both poly and PEX service tubing in that wall class. If your service line is a different SDR (thinner or thicker wall) the pipe-side will not seat correctly, so match the SDR11 rating, not just the 1-1/2 inch nominal size.
2) What does the threaded end of the A.Y. McDonald 4430-007 riser connect to?
It terminates in a 1-1/2 inch MNPT male thread, so it threads straight into a female 1-1/2 inch NPT inlet on a meter setter, curb stop, or an above-grade shutoff or valve. No adapter is needed if the receiving component is 1-1/2 inch FIP.
3) How deep a service line will a 36 inch X-Riser reach?
The 4430-007 has a 36 inch overall length, so it carries the buried line up roughly three feet from the pipe connection to the threaded outlet at grade. If your bury depth from the service line to the meter or curb stop connection point is deeper than that, a 36 inch riser will not reach and you need a longer riser length.
4) Is the A.Y. McDonald X-Riser metal or plastic, and will it hold up buried?
The body is zinc die cast (ZDC), a rigid corrosion-resistant metal chosen for the mechanical stress at a below-grade to above-grade transition. That rigidity is the point: it gives the flexible poly or PEX line a solid anchor where it turns up to a threaded connection, instead of relying on a field-built assembly of couplings and nipples.
5) Do I still need couplings and nipples if I use the 4430-007 riser?
No. The X-Riser is a single component that replaces a field-fabricated riser assembly: pipe side takes the 1-1/2 inch SDR11 service line, the other end gives you 1-1/2 inch male NPT at grade. You supply whatever the pipe-side joint method requires on your line and the mating female fitting at the top, but the multiple cut-and-thread joints in the middle go away.
6) Can I use this X-Riser on a PEX water service line?
Yes, provided the PEX is 1-1/2 inch IPS-sized to SDR11 / .173 wall. The pipe side is dimensioned to that wall class, and A.Y. McDonald lists SDR11 poly and PEX riser assemblies as an intended use. Copper tube size PEX will not fit; this is an IPS-dimensioned connection.
7) What is the actual A.Y. McDonald model number for the 4430-007 X-Riser?
The catalogue number is 4430-007 and the factory model designation is XR-31K-24-36-ZDC, where the 36 is the riser length and ZDC is the zinc die cast body. Use 4430-007 when ordering; the XR number is useful when cross-checking against an A.Y. McDonald riser table.
