This black HDPE fitting joins two sections of same-diameter pipe using the socket fusion method, which applies heat to both the pipe end and fitting socket before pressing them together to form a permanent, leak-free bond. It is sized at 3 inches and is intended for use in pressurized water distribution applications. Licensed plumbers and pipefitters are the primary installers for this type of fusion fitting.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for residential and commercial water supply systems where HDPE pipe is the specified material. HDPE socket fusion fittings are commonly used in municipal water distribution, geothermal loop systems, irrigation mains, and underground service lines where corrosion resistance and long service life are required. The black color indicates standard HDPE formulation used in water service and non-potable applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch socket fusion connection for HDPE pipe\u003c\/li\u003e\n  \u003cli\u003eBlack HDPE construction offers corrosion resistance and flexibility\u003c\/li\u003e\n  \u003cli\u003eSocket fusion joint creates a permanent, monolithic bond when properly fused\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard HDPE water service pipe of the same outside diameter and SDR rating\u003c\/li\u003e\n  \u003cli\u003eNo threading, gluing, or mechanical fasteners required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard coupling for 3-inch HDPE water service pipe joined by socket fusion.

Shut off and depressurize the water line before cutting or joining pipe. Follow the pipe and fitting manufacturer heating times and temperatures precisely, as under- or over-heating will result in a failed joint. Work must comply with applicable local plumbing codes and ASTM standards governing HDPE fusion procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Socket Fusion\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: HDPE (High-Density Polyethylene)\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 Supply\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: 69-310903\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARCO","offers":[{"title":"Default Title","offer_id":51396255777074,"sku":"69-310903","price":35.15,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312833188.jpg?v=1782828343","url":"https:\/\/voomisupply.com\/products\/harco-69-310903-hdpe-socket-fusion-coupling-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
