It features a 1\/8 inch tube OD with 5\/16-28 UNF threads on both ends, providing a secure flare-to-flare connection rated for up to 2800 psi working pressure and temperatures up to 250 degrees F. The brass construction resists corrosion and handles the mechanical stress of high-pressure line connections. Licensed HVAC technicians, plumbers, and hydraulic system technicians use this fitting during line assembly and repair work where an inline union connection is required.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial refrigeration line sets, hydraulic tubing assemblies, and other fluid systems requiring an inverted flare union joint. It is commonly installed in brake line systems, HVAC refrigerant circuits, and hydraulic control lines where a removable, pressure-rated inline connection is needed. The compact 0.6 inch overall length makes it practical in tight spaces or panel-mount plumbing configurations. The 5\/16-28 UNF thread size conforms to SAE J51 standards, making it a direct-fit option in systems engineered to that specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInverted flare union configuration with flare x flare end connections on both sides\u003c\/li\u003e\n  \u003cli\u003eRated to 2800 psi maximum working pressure for high-pressure line applications\u003c\/li\u003e\n  \u003cli\u003eTemperature rating up to 250 degrees F (121 degrees C)\u003c\/li\u003e\n  \u003cli\u003e5\/16-28 UNF thread size conforming to SAE J51 standard\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance in fluid and refrigerant service\u003c\/li\u003e\n  \u003cli\u003eUL Listed and SAE J51 compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inverted flare union replacement for hydraulic, refrigerant, and fluid-control tubing systems using 1\/8 inch OD tube with 5\/16-28 UNF inverted flare connections per SAE J51.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician, hydraulic system technician, or licensed plumber. Depressurize and isolate the line completely before disconnecting or installing any flare fitting. Use a properly calibrated flaring tool to ensure the tube end meets SAE J51 flare geometry before tightening — an improperly flared seat is the leading cause of leaks at inverted flare connections. Do not overtighten; snug the fitting to seat the flare and follow applicable SAE or system manufacturer torque guidance for the fitting size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Inverted Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 2800 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F (121 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE J51, UL Listed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 42IFHD-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543538827570,"sku":"42IFHD-2","price":16.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f59dd89e66d78129e82b28214fce2315_00b47be8-3488-4ef4-8162-fbc7a0dc5c6c.jpg?v=1785920093","url":"https:\/\/voomisupply.com\/products\/parker-42ifhd-2-brass-inverted-flare-union-1-8-in-tube-od","provider":"Voomi Supply","version":"1.0","type":"link"}
