Constructed from ductile iron with a rust-inhibiting orange painted finish, this coupling handles a temperature range of -30 to 230 degrees F. It features an EPDM gasket and measures 8.25 inches in length with a 4.5-inch OD, making it a robust mechanical joining solution for 4-inch nominal pipe. Licensed plumbers and pipefitters install this fitting in commercial and industrial HDPE piping applications where grooved mechanical coupling is specified.\u003c\/p\u003e\n\u003cp\u003eThis coupling is engineered specifically for HDPE pipe systems requiring a grooved end connection style. It is suited for use in commercial mechanical systems, industrial process piping, and water distribution applications where HDPE-to-grooved-end transitions are required. The included hardware — four zinc electroplated bolts, heavy hex nuts, zinc-coated hardened steel washers, and a Grade E Green EPDM gasket — allows for a complete installation without sourcing additional fasteners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDuctile iron body with rust-inhibiting orange painted finish for corrosion resistance in exposed environments\u003c\/li\u003e\n  \u003cli\u003eEPDM gasket rated for -30 to 230 degrees F, suitable for a broad range of fluid and ambient temperatures\u003c\/li\u003e\n  \u003cli\u003eGrooved end style compatible with standard mechanical coupling installation practices\u003c\/li\u003e\n  \u003cli\u003e4-inch nominal size with 4.5-inch OD and 8.25-inch overall length\u003c\/li\u003e\n  \u003cli\u003eIncludes all required hardware: zinc electroplated bolts and nuts, hardened steel washers, and Grade E EPDM gasket\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for HDPE pipe transition applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 4-inch nominal HDPE pipes requiring a grooved end mechanical coupling transition.

Power down or depressurize the system fully before disassembly or fitting installation. Ensure pipe ends are properly grooved to the correct specification before seating the gasket and coupling housing. Tighten bolts evenly in an alternating pattern to achieve uniform gasket compression without over-torquing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 8.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -30 to 230 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Grooved\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Ductile Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGasket Material\u003c\/strong\u003e: EPDM (Grade E Green)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Rust Inhibiting Orange Painted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: (4) 0.5 x 3 inch Zinc Electroplated Bolts, Zinc Electroplated Heavy Hex Nuts, Zinc Coated Hardened Steel Washers, Grade E Green EPDM Gasket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Taiwan\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: ASC ENGINEERED SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 390060739\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51233220329778,"sku":"0390060739","price":412.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307626632.jpg?v=1780094578","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-390060739-fig-7307-hdpe-coupling-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
