Built from nickel-plated steel, this connector provides a corrosion-resistant, durable connection point at the hose or tool interface. The 3\/4 inch MNPT thread engages standard NPT-tapped ports and manifolds, and the 3\/4 inch body diameter matches common Industrial Interchange receiver sockets. It is typically installed by industrial maintenance technicians, construction air tool operators, and mechanical contractors working with high-volume pneumatic circuits.\u003c\/p\u003e\n\u003cp\u003eThis coupling fits applications where Industrial Interchange-type quick-connect components are specified, including plant floor pneumatic distribution, construction air tools, and compressor outlet drops. The MNPT thread style allows direct installation into tool inlets, hose fittings, or manifold ports without adapters in most standard setups. The nickel-plated finish adds resistance to light corrosion and surface wear, making it suitable for both indoor shop environments and covered outdoor work areas.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIndustrial Interchange coupling type for broad tool and hose compatibility within that style\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch MNPT thread for direct connection to standard NPT-tapped ports\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch body diameter matches standard Industrial Interchange receiver sockets\u003c\/li\u003e\n  \u003cli\u003eNickel-plated steel construction for corrosion resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eThreaded connection type ensures a secure, vibration-resistant fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or inline connector for Industrial Interchange-style pneumatic systems using 3\/4 inch MNPT-threaded ports. Consult system documentation to confirm coupling style and thread size before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanical or pneumatic technicians. Depressurize and lock out the compressed air supply completely before installing or removing any coupling. Apply thread sealant tape rated for pneumatic service to the MNPT threads and tighten to fitting manufacturer specifications using an appropriately sized pipe wrench. Do not over-tighten, as steel NPT threads can damage mating ports if excessive torque is applied.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Connector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterchange Type\u003c\/strong\u003e: Industrial\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Nickel-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\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: COILHOSE PNEUMATICS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COILHOSE PNEUMATICS","offers":[{"title":"Default Title","offer_id":51562691297586,"sku":"3401","price":36.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5f5707eaf88b8aef326483a7ac90d54.jpg?v=1786482283","url":"https:\/\/voomisupply.com\/products\/coilhose-pneumatics-3401-3-4-inch-mnpt-pneumatic-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
