Built from steel with a zinc finish, this coupling features a 3\/8 inch male NPT (MNPT) thread and a 7\/8 inch body diameter, making it a standard-duty component for connecting and disconnecting air lines quickly without tools. The zinc finish provides corrosion resistance in typical shop and industrial environments. HVAC technicians, plumbers, and general tradespeople install this type of coupling on compressors, pneumatic tools, and service equipment where fast, secure line connections are required.\u003c\/p\u003e\n\u003cp\u003eThis quick connect plug is suited for residential and light commercial pneumatic systems, including air compressor manifolds, pneumatic tool lines, and service vehicle air supply setups. The 3\/8 inch hose inside diameter and MNPT thread configuration make it compatible with standard NPT-threaded fittings commonly found in shop and field service applications. It is sold individually and intended for direct installation into mating quick connect coupler bodies of the same thread size and coupling series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick connect plug design allows fast tool-free line connection and disconnection\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch MNPT thread for compatibility with standard NPT-threaded ports and couplers\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch body diameter suited for standard quick connect coupler bodies\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch hose inside diameter for proper flow in typical pneumatic tool lines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit plug for pneumatic quick connect coupler systems using 3\/8 inch MNPT threaded connections and standard 7\/8 inch body diameter coupler bodies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by HVAC technicians, plumbers, or maintenance tradespeople familiar with pneumatic fittings. Always depressurize and bleed down the air line before removing or installing any pneumatic coupling. Apply thread sealant tape to the MNPT threads per manufacturer and applicable plumbing code requirements before threading into the receiving port. Do not overtighten; use an appropriately sized wrench and follow standard NPT hand-tight-plus-turns practice.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Quick Connect Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHose Inside Diameter\u003c\/strong\u003e: 3\/8 inch\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: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141734\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: W04-31131-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723580080434,"sku":"W04-31131-B","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45851f4d8e6552579d511b58f17fa9dd.jpg?v=1788606627","url":"https:\/\/voomisupply.com\/products\/value-collection-w04-31131-b-pneumatic-hose-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
