Built with a brass and steel construction and a zinc-plated finish, this threaded coupler provides a secure, leak-resistant connection rated to 232 psi maximum working pressure. The 1\/2-inch body diameter accepts a 3\/8-inch inside diameter hose, and the 3\/8-inch male NPT thread allows direct installation into standard ports and manifolds. Licensed HVAC technicians, industrial mechanics, and pneumatic system installers will encounter this fitting in air-tool supply lines, compressor outlets, and similar high-cycle pneumatic circuits.\u003c\/p\u003e\n\u003cp\u003eThis coupler is suited for both light industrial and heavy shop environments where a safety-locking connection is required to prevent accidental disconnection under pressure. The industrial interchange configuration makes it broadly compatible with standard pneumatic quick-connect systems. Rated for temperatures from -4 degrees F to 212 degrees F, it handles typical ambient and process conditions in most North American shop and plant environments. The threaded connection type makes installation straightforward on existing NPT-threaded ports without adapters in most cases.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSafety coupler design helps prevent unintended hose disconnection under live pressure\u003c\/li\u003e\n  \u003cli\u003e232 psi maximum working pressure suits most industrial compressed-air applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch MNPT thread connects directly to standard NPT ports and manifolds\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch body diameter with 3\/8-inch hose inside diameter for matched flow\u003c\/li\u003e\n  \u003cli\u003eBrass and steel construction with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -4 degrees F to 212 degrees F (-20 degrees C to 100 degrees C)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an industrial interchange safety coupler compatible with standard pneumatic quick-connect systems using 3\/8-inch MNPT threaded connections and 1\/2-inch body diameter fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or pneumatic systems technician. Depressurize and bleed down the air line completely before removing any existing coupler or fitting. Apply thread sealant tape to the MNPT threads per standard practice, taking care not to leave loose tape ends that could enter the air circuit. Confirm that the mating plug or nipple is also rated to at least 232 psi before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Safety Coupler\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\/8 inches\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: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHose Inside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 232 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 212 degrees F (100 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -4 degrees F (-20 degrees C)\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: Brass, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: CEJN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10 550 2454\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CEJN","offers":[{"title":"Default Title","offer_id":51718065652018,"sku":"10 550 2454","price":74.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c638e113b32cf4cc6f3ece4ab609264d.jpg?v=1788549268","url":"https:\/\/voomisupply.com\/products\/cejn-10-550-2454-safety-coupler-1-2-in-3-8-mnpt-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
