A.Y. McDonald 4430-005 X-Riser 1-1/4" IPS SDR11 x 1-1/4" MNPT Transition Riser, 36" Length

The A.Y. McDonald 4430-005 X-Riser is a below-grade to above-grade transition fitting designed to connect 1 1/4" IPS SDR11 (.151" wall) polyethylene pipe to a 1 1/4" MNPT threaded connection, delivering a factory-built riser assembly in a 36" overall length. Identified in manufacturer data as the XR-27G-20-36-ZDC configuration, this X-Riser is built for direct-bury service line installations where a transition from buried PE pipe to a rigid above-grade or meter-set connection is required. The riser combines a polyethylene barrel with a threaded MNPT outlet, giving installers a single, pre-manufactured component at the critical transition point.

Key Features

  • Trade Size: 1 1/4" IPS (iron pipe size) SDR11 with a .151" nominal wall thickness for the buried polyethylene leg.
  • Threaded Outlet: 1 1/4" MNPT (male national pipe thread) connection for above-grade or meter-set hookup.
  • Overall Length: 36" riser length, spanning the transition from below-grade pipe to the above-grade threaded connection.
  • Transition Design: Purpose-built X-Riser configuration joins polyethylene SDR11 pipe to MNPT threads in a single fitting, reducing the number of field joints at the riser location.
  • SDR11 Rated Pipe Leg: Standard Dimension Ratio 11 wall construction on the polyethylene section, consistent with common service riser applications.
  • Model Designation: Manufactured and identified as XR-27G-20-36-ZDC per A.Y. McDonald product coding.

Technical Specifications

  • Pipe Size: 1 1/4" IPS
  • Wall Type: SDR11 / .151" wall
  • Threaded End: 1 1/4" MNPT
  • Length: 36"
  • Model Code: XR-27G-20-36-ZDC

Typical Applications

  • Below-Grade to Above-Grade Service Line Transitions
  • Polyethylene to Threaded Riser Connections
  • Meter-Set and Service Riser Installations
  • New Construction and Service Line Replacement
  • Direct-Bury Distribution Piping Transitions

Why A.Y. McDonald?

A.Y. McDonald manufactures the 4430-005 X-Riser as a factory-built transition assembly, combining SDR11 polyethylene pipe with a threaded MNPT outlet so contractors get a consistent, single-source riser at the point where buried service piping comes above grade. Choosing a factory-built transition fitting like the 4430-005 helps installers standardize riser connections across service line and meter-set installations.

A.Y. McDonald 4430-005 – Frequently Asked Questions

1) What size and type of poly pipe does the A.Y. McDonald 4430-005 X-Riser connect to?
The 4430-005 X-Riser takes 1-1/4 inch IPS SDR11 polyethylene pipe with a .151 inch nominal wall on the buried leg. If your service line is CTS sizing or a different SDR (thinner or thicker wall), the riser's PE leg will not match it. Confirm the pipe stamp reads 1-1/4 IPS SDR11 before you order.
2) What thread is on the above-grade end of the 4430-005 riser?
A 1-1/4 inch MNPT male pipe thread. It threads straight into a female NPT fitting, meter-set ell, or valve at 1-1/4 inch. There is no adapter included, so if your meter set or above-grade piping is a different size, you need a bushing or reducing coupling to land it.
3) How long is the A.Y. McDonald 4430-005 X-Riser, and will 36 inches reach above grade?
Overall length is 36 inches, measured from the buried PE end to the threaded outlet. That is the full span you get from the depth of the service line up to the above-grade connection, so check your bury depth against it: at typical burial depths deeper than about 3 feet the outlet will not clear grade and you need a longer riser instead.
4) Why use a factory-built transition riser instead of fusing a poly-to-thread adapter in the ditch?
The X-Riser arrives as one pre-manufactured assembly with the PE barrel and the MNPT outlet already joined, so the transition joint is made in the factory rather than in the trench. That removes a field joint at the single point most likely to leak on a buried service line, and it gives you the same riser geometry on every meter set instead of a hand-built one each time. Field-built alternative is pipe plus a separate transition fitting, which means one more joint to test and inspect.
5) Is the 4430-005 X-Riser suitable for direct burial?
Yes, the PE leg is intended for direct-bury service line work, with the threaded 1-1/4 inch MNPT end left above grade. Typical uses are new-construction service lines, service line replacement, meter-set risers and direct-bury distribution piping transitions.
