Constructed from ductile iron, this fitting measures 4 inches on the grooved end and 6 inches on the MPT end, weighing 5.40 pounds. It is installed by licensed pipefitters and mechanical contractors working on fire protection, HVAC hydronic systems, or industrial piping where grooved couplings must connect to threaded components.\u003c\/p\u003e\u003cp\u003eThis adapter nipple is suited for commercial and industrial piping installations where grooved mechanical joining meets threaded pipe runs. The Gruvlok product line is commonly used in wet-pipe fire suppression systems, chilled water loops, and condenser water systems. The 4 inches x 6 inches sizing accommodates mid-to-large diameter piping found in these applications, making it a practical transition fitting for mechanical rooms and above-ceiling installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDuctile iron construction for strength and durability in demanding piping environments\u003c\/li\u003e\n\u003cli\u003eGrooved end accepts standard grooved mechanical couplings for quick, reliable connections\u003c\/li\u003e\n\u003cli\u003eMPT end threads into standard female-threaded fittings or equipment ports\u003c\/li\u003e\n\u003cli\u003e4 inches x 6 inches sizing suits mid-to-large diameter commercial and industrial piping systems\u003c\/li\u003e\n\u003cli\u003e5.40 pound robust build supports high-pressure and high-flow piping applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style grooved-to-threaded transition fitting for use in commercial and industrial piping systems that incorporate Gruvlok-style grooved mechanical couplings on 4-inch pipe runs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed pipefitter or mechanical contractor in accordance with applicable mechanical and fire protection codes. Depressurize and drain the piping system fully before removing or installing any grooved fittings. Verify that the grooved end groove dimensions meet the coupling manufacturer specifications before engaging the mechanical coupling. Do not overtighten the MPT connection; use appropriate thread sealant compatible with the system fluid.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Material\u003c\/strong\u003e: Ductile Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 4 inches x 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 5.40 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 390033199\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51233533264178,"sku":"0390033199","price":81.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307627623.jpg?v=1780102461","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-390033199-grooved-mpt-adapter-nipple","provider":"Voomi Supply","version":"1.0","type":"link"}
