It connects a 5\/16-inch OD flared tube to a 1\/4-18 NPTF male pipe thread, changing line direction by 45 degrees without the need for additional adapters. Rated to 1200 psi maximum working pressure and 250 degrees F maximum working temperature, this fitting is built for demanding service environments. The brass construction offers corrosion resistance and reliable sealing performance at both the flare and threaded connections. Typical installers include HVAC technicians, refrigeration mechanics, and hydraulic system technicians.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial HVAC systems, automotive air conditioning, refrigeration equipment, and hydraulic fluid lines where an inverted 45-degree flare connection to a male NPTF port is required. The 5\/16-inch tube OD and 1\/4-18 thread size are common in refrigerant line sets and low-to-medium-pressure hydraulic circuits. It is packaged and sold individually, making it appropriate for single-point repair or new installation work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInverted 45-degree flare elbow geometry for compact directional changes in tight line routing\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and compatibility with refrigerants and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eRated to 1200 psi maximum working pressure for reliable performance in pressurized systems\u003c\/li\u003e\n  \u003cli\u003eMaximum working temperature of 250 degrees F for high-temperature service environments\u003c\/li\u003e\n  \u003cli\u003eFlare x MNPTF end connections for secure leak-resistant joints at both the tube and pipe ends\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J51 standards and is UL Listed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for systems using 5\/16-inch OD inverted flare tube connections with 1\/4-18 NPTF male pipe thread ports, consistent with SAE J51 inverted flare standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician, refrigeration mechanic, or hydraulic system technician. Always depressurize and isolate the system before removing or installing fittings. Ensure the tube end is properly flared to the inverted 45-degree specification before assembly, and inspect threads for damage prior to installation. Follow applicable SAE and system-manufacturer torque and assembly guidelines; do not overtighten, as brass fittings can be damaged by excessive force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: 45 Degree Inverted Elbow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x MNPTF\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: 1.16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 259IFHD-5-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538969198898,"sku":"259IFHD-5-4","price":71.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89267a5e117057a9ed6f9e154b3bb168.jpg?v=1785831303","url":"https:\/\/voomisupply.com\/products\/parker-259ifhd-5-4-brass-inverted-45-flare-elbow-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
