The taper tapped thread profile creates a self-tightening seal as the fitting is made up, reducing the need for supplemental thread sealants in many low-pressure applications. Galvanized steel construction provides corrosion resistance suitable for water service and general-purpose plumbing and mechanical piping. At 4.61 pounds, this is a full-sized heavy-duty coupling intended for commercial and industrial piping runs. Licensed plumbers and pipefitters are the primary installers of fittings in this size range.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in 4-inch threaded steel piping systems found in commercial plumbing, mechanical rooms, fire protection, and industrial process piping. The taper tapped configuration is a standard end-to-end coupling that joins two male-threaded pipe ends. It is commonly specified where a removable, threaded mechanical connection is required in steel piping. This size is typical in larger commercial and light industrial installations rather than residential service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch fitting size for large-diameter threaded steel piping\u003c\/li\u003e\n  \u003cli\u003eTaper tapped thread form creates a self-tightening, pressure-resistant joint\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel construction resists corrosion in water and general mechanical service\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty weight class at 4.61 pounds, suitable for commercial and industrial use\u003c\/li\u003e\n  \u003cli\u003eStandard threaded coupling profile for straightforward inline pipe joining\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 4-inch threaded galvanized steel piping systems in commercial plumbing and mechanical applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of 4-inch threaded steel couplings should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Isolate and depressurize the piping system completely before removing or installing any threaded fittings. Apply an approved thread sealant compound or PTFE tape to male threads before makeup. Do not overtighten, as this can crack the fitting or distort threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Taper Tapped Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.61 pounds\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: 321200339\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51233488634162,"sku":"0321200339","price":199.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307627386.jpg?v=1780101211","url":"https:\/\/voomisupply.com\/products\/asc-321200339-taper-tapped-galvanized-steel-coupling-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
