Nomaco HDPECOUP114 Hdpe Socket Coupling 1-1/4 in

Product Description

The NOMACO HDPECOUP114 is a 1-1/4 inch HDPE socket coupling designed to join two sections of HDPE pipe in a secure, leak-resistant connection. High-density polyethylene construction gives this fitting strong resistance to corrosion, chemicals, and moisture, making it well suited for water service, irrigation, and underground piping applications. The socket-style ends accept pipe ends directly, allowing for heat fusion or solvent-compatible joining depending on the installation method. Plumbers and pipe fitters install this fitting as part of new construction or repair work where a reliable, mid-run pipe joint is required.

This socket coupling is sized for 1-1/4 inch pipe and is commonly used in residential and light commercial water service lines, geothermal loop systems, and irrigation distribution networks. Its HDPE material is compatible with potable water systems and performs well in both above-grade and buried installations. The fitting is appropriate for any application where a straight, in-line pipe connection is needed and long-term durability against soil contact or chemical exposure is a priority.

Key Features

• 1-1/4 inch socket ends for direct pipe insertion and joining
• High-density polyethylene (HDPE) construction resists corrosion and chemical degradation
• Suitable for potable water, irrigation, and geothermal piping systems
• Compatible with both buried and above-grade installations
• Lightweight design simplifies handling and installation in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch HDPE piping systems in water service, irrigation, and similar applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable IPC and local plumbing code requirements. Shut off water supply and depressurize the line before cutting or joining pipe sections. Socket fusion joints require a properly calibrated fusion tool heated to the manufacturer-specified temperature range — do not attempt fusion with improvised heat sources. Inspect socket ends for debris or moisture before joining to ensure a full, void-free connection.
