Nomaco PERISER1 Meter Riser 1 Inch Steel Xpoly

Product Description

The NOMACO PERISER1 is a 1-inch meter riser designed for gas service applications. This steel and cross-linked polyethylene (Xpoly) assembly transitions gas piping from the underground supply line up to the meter set. The combination of steel and Xpoly construction provides corrosion resistance below grade and mechanical strength above grade. Licensed plumbers and gas fitters install this component as part of a residential or light commercial gas meter installation.

The PERISER1 is sized for 1-inch service lines and is suited for residential and light commercial natural gas meter sets. It is typically installed where the underground Xpoly distribution piping surfaces and connects to the above-ground steel meter riser assembly. This riser bridges the transition between buried flexible piping and the rigid meter connection point.

Key Features

• 1-inch nominal size for standard residential and light commercial gas service
• Steel upper section provides rigid, durable above-grade support for the meter set
• Cross-linked polyethylene (Xpoly) lower section offers corrosion resistance and flexibility below grade
• Combines two materials in one assembly to simplify the underground-to-above-grade transition

Compatibility

Designed as an OEM-style replacement or new-installation component for 1-inch residential and light commercial natural gas meter riser applications using cross-linked polyethylene service piping.

Installation Notes

Installation must be performed by a licensed plumber or gas fitter in accordance with local codes and the International Fuel Gas Code (IFGC). Shut off the gas supply at the main service valve before beginning any work on the riser assembly. The below-grade Xpoly section must be properly bedded and protected per local requirements, and all above-grade steel connections must be leak-tested with approved methods before restoring service.
