Nomaco HDPEPIPE114 Hdpe Poly Water Pipe 1-1/4 in

Product Description

The NOMACO HDPEPIPE114 is a 1-1/4-inch high-density polyethylene (HDPE) water pipe manufactured to PE3408 material designation. PE3408 specifies a resin cell classification that defines density, melt index, flexural modulus, tensile strength, and slow crack growth resistance, making it a recognized standard for pressure-rated potable water and utility piping applications. This pipe is installed by licensed plumbers and water-system contractors in both residential and light commercial settings where a flexible, corrosion-resistant conduit is required.

HDPE PE3408 pipe is commonly used in potable water distribution, irrigation systems, geothermal loop piping, and well-water supply lines. Its flexibility relative to rigid PVC makes it suitable for direct-burial installations and trenchless applications such as horizontal directional drilling. Contractors working on water service laterals, pump discharge lines, and rural water systems frequently specify PE3408-grade HDPE for its long service life and resistance to soil movement and freeze-thaw cycling.

Key Features

• PE3408 HDPE material designation meets recognized standards for pressure-rated water piping
• 1-1/4-inch nominal diameter suitable for residential service lines and irrigation mains
• Corrosion-resistant polyethylene construction requires no cathodic protection
• Flexible profile allows direct-burial and trenchless installation methods
• Suitable for potable water, irrigation, and utility fluid conveyance

Compatibility

Designed as an OEM-style replacement and standard-stock HDPE pipe for residential and light commercial water distribution, irrigation, and utility piping systems requiring 1-1/4-inch nominal HDPE conduit.

Installation Notes

Installation should be performed by a licensed plumber or water-system contractor in accordance with applicable local plumbing codes and ASTM D2774 guidelines for underground installation of thermoplastic pressure piping. Shut off and depressurize the supply system before cutting into any existing line. Joints are typically made using heat fusion, mechanical compression fittings, or insert fittings rated for HDPE service — confirm fitting compatibility with the pipe's outside diameter before assembly. Do not use solvent-weld fittings designed for PVC or CPVC on HDPE pipe.
