Socket fusion fittings join HDPE pipe by heating both the pipe end and the fitting socket to a controlled melt temperature, then pressing them together to form a permanent, leak-free bond. This coupling is used to join two straight runs of 3\/4 inch HDPE pipe and is installed by licensed plumbers and water service technicians working on underground or above-grade water distribution systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and light commercial water service lines where HDPE pipe is the specified material. HDPE is commonly chosen for its resistance to corrosion, chemical exposure, and ground movement, making it a standard choice for buried water mains and service laterals. The black colorway is typical of HDPE water service fittings and aids in UV resistance for above-grade or partially exposed installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch socket fusion end connections for permanent, heat-fused joints\u003c\/li\u003e\n  \u003cli\u003eHigh-density polyethylene (HDPE) construction resists corrosion and chemical degradation\u003c\/li\u003e\n  \u003cli\u003eBlack finish provides UV resistance for exposed or partially buried installations\u003c\/li\u003e\n  \u003cli\u003eStraight coupling configuration joins two sections of 3\/4 inch HDPE pipe in line\u003c\/li\u003e\n  \u003cli\u003eDesigned for potable water and general water service applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement fitting compatible with standard 3\/4 inch HDPE water service pipe systems using socket fusion joining methods.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSocket fusion fittings must be installed by a qualified plumber or pipe fusion technician using a properly sized socket fusion tool calibrated to the correct melt temperature for HDPE. Always depressurize and isolate the water service line before cutting and fitting. Allow the fused joint to cool completely without movement before restoring pressure. Installation should comply with applicable local plumbing codes and ASTM standards for HDPE water service piping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Density Polyethylene (HDPE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Socket Fusion\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Water Service\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrder Increment\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HARCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69-3109B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARCO","offers":[{"title":"Default Title","offer_id":51396264165682,"sku":"69-3109B","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312833122.jpg?v=1782828530","url":"https:\/\/voomisupply.com\/products\/harco-69-3109b-3-4-inch-hdpe-socket-fusion-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
