Harco 69-3109C Hdpe Socket Fusion Coupling 1 Inch

Product Description

The HARCO 69-3109C is a 1-inch socket fusion coupling designed for high-density polyethylene (HDPE) water service piping. This black HDPE fitting joins two lengths of 1-inch HDPE pipe using the socket fusion method, creating a strong, leak-resistant thermoplastic bond without mechanical fasteners. Socket fusion fittings are a standard choice in municipal water distribution, rural water systems, and underground service line installations where corrosion resistance and long service life are required. Plumbers and utility contractors install this fitting as part of pressure-rated HDPE piping assemblies.

The 69-3109C is suited for potable water service lines, irrigation mains, and underground water distribution in residential and light commercial applications. The black pigmentation provides UV resistance for above-grade staging and outdoor storage prior to burial. This coupling is appropriate for use wherever 1-inch HDPE pipe is specified for water service work and socket fusion joining is the required connection method.

Key Features

• Socket fusion end connections for a monolithic, leak-resistant thermoplastic joint
• Black HDPE construction provides UV resistance and corrosion immunity
• 1-inch nominal size fits standard SDR-series HDPE water service pipe
• No mechanical fasteners, gaskets, or adhesives required for the fusion joint
• Suitable for buried water service and distribution piping applications

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 1-inch HDPE water service piping systems joined by the socket fusion method.

Installation Notes

Socket fusion fittings must be installed by a plumber or utility technician trained in thermoplastic fusion procedures. The pipe and fitting surfaces must be clean, dry, and cut square before heating with a properly sized fusion tool to the correct face temperature. Water service must be shut off and the line depressurized before cutting into an existing system. Follow local plumbing code and ASTM F2389 or applicable HDPE joining standards for procedure and inspection requirements.
