Nomaco PESFCOUP3 Ips Socket Fusion Coupling 3 Inches

Product Description

The NOMACO PESFCOUP3 is a 3-inch IPS socket fusion coupling designed for joining polyethylene piping systems using the socket fusion welding method. This fitting creates a permanent, pressure-rated joint by heating mating surfaces to a precise melt temperature and pressing them together without additional adhesives or mechanical fasteners. It is used in water service, geothermal, and industrial fluid transport applications where a leak-free thermoplastic connection is required. Licensed plumbers and pipefitters typically handle installation, particularly on systems subject to pressure testing or buried service.

The PESFCOUP3 is suited for IPS-sized polyethylene pipe in residential, commercial, and light industrial settings. Socket fusion couplings of this type are commonly specified on potable water service laterals, geothermal ground loop headers, and reclaimed water distribution lines. The 3-inch IPS sizing covers a common mid-range diameter used in both new construction and pipe repair or extension work where a straight inline coupling is needed.

Key Features

• Socket fusion design creates a monolithic, leak-resistant thermoplastic joint
• IPS sizing ensures compatibility with standard iron pipe size polyethylene pipe
• No adhesives, clamps, or mechanical fasteners required for the fusion joint
• Suitable for buried and above-ground polyethylene piping systems
• 3-inch bore accommodates a widely used service and distribution pipe size

Compatibility

Designed as an OEM-style socket fusion fitting for use with 3-inch IPS-dimension polyethylene pipe in pressure-rated thermoplastic piping systems.

Installation Notes

Installation requires a socket fusion tool set calibrated to the correct melt temperature for the pipe material and wall thickness. Shut off and depressurize the piping system completely before cutting or joining pipe. Follow ASTM F2389 or the pipe manufacturer fusion procedures for heat soak and cooling times. This work is typically performed by a licensed plumber or qualified pipefitter familiar with thermoplastic fusion methods.
