Nomaco PESFCOUP114 Socket Fusion Coupling 1-1/4 Inch Ips

Product Description

The NOMACO PESFCOUP114 is a 1-1/4 inch IPS socket fusion coupling designed for joining polyethylene piping systems using the socket fusion joining method. This fitting creates a permanent, pressure-rated connection between two pipe segments of equal diameter. It is used in potable water, geothermal, and general fluid distribution systems where reliable PE pipe connections are required. Licensed plumbers and piping contractors handle installation as part of larger underground or above-grade distribution projects.

This coupling is sized for 1-1/4 inch Iron Pipe Size pipe and is suited for residential and light commercial plumbing, irrigation, and geothermal loop applications. Socket fusion fittings are commonly installed where a heat-tool fusion joint is preferred over mechanical or threaded connections, offering a leak-free, monolithic connection in systems carrying water or compatible fluids.

Key Features

• 1-1/4 inch IPS socket fusion end connections for equal-diameter pipe joining
• Socket fusion design produces a continuous, permanent polyethylene bond
• Sized to IPS dimensions for broad compatibility with standard PE piping systems
• No threads, clamps, or mechanical fasteners required at the joint

Compatibility

Designed as an OEM-style replacement and standard fitting for 1-1/4 inch IPS polyethylene piping systems using socket fusion joining.

Installation Notes

Socket fusion couplings are installed by licensed plumbers or certified pipe fusion technicians using manufacturer-specified socket fusion tooling, including a heating iron and socket fusion tool set. The pipe and fitting surfaces must be clean, dry, and free of debris before heating. Follow applicable plumbing codes, including IPC guidelines, for joint preparation, heating times, and cooling periods before pressurizing the system. Never force or disturb the joint during the cooling phase, as this compromises the integrity of the fusion bond.
