It features a 5\/16-inch tube outside diameter and a 1\/2-20 UNF thread on both ends, providing a secure flare-to-flare connection. Rated to 1200 psi maximum working pressure and 250 degrees F maximum working temperature, this union is built for demanding service conditions. At 0.70 inches overall length, the compact body fits tight under-hood or panel installations. Licensed and field technicians working on automotive brake lines, HVAC refrigerant circuits, or hydraulic tubing systems typically install this fitting.\u003c\/p\u003e\n\u003cp\u003eThis inverted flare union is suited for residential and light commercial fluid-line assemblies where two tube runs must be coupled inline. Common applications include automotive and truck brake hydraulic lines, HVAC copper or steel tubing connections, and other systems using SAE J51-standard inverted flare fittings. The brass construction resists corrosion in wet and oil-contaminated environments. The fitting ships individually but is available in minimum order quantities of 5 units, making it practical for service stock and repair kits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInverted flare union design joins two flared tube ends without a separate nut on each side\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch tube outside diameter with 1\/2-20 UNF thread on both ends\u003c\/li\u003e\n  \u003cli\u003e1200 psi maximum working pressure for high-pressure fluid line service\u003c\/li\u003e\n  \u003cli\u003e250 degrees F maximum working temperature rating\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance in hydraulic and refrigerant service\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J51 standard and carries UL Listed certification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for fluid-transfer and hydraulic tubing systems using SAE J51 inverted flare connections with a 5\/16-inch tube outside diameter and 1\/2-20 UNF thread specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed technician familiar with hydraulic, brake, or refrigerant line service. Depressurize and isolate the fluid circuit completely before disconnecting or installing any fittings. Use the appropriate flaring tool to produce a clean, consistent inverted flare seat before threading the fitting; a damaged or uneven flare is the primary cause of leaks. Tighten to the tool manufacturer's recommended procedure for brass inverted flare fittings — do not over-tighten, as brass threads can gall or crack.\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\u003eTube Outside Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1200 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: 0.71 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541986410802,"sku":"42IFHD-5","price":38.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f59dd89e66d78129e82b28214fce2315_989993c9-5dbd-4e90-aef6-a86278a6d096.jpg?v=1785888969","url":"https:\/\/voomisupply.com\/products\/parker-42ifhd-5-brass-inverted-flare-union-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
