It uses a 45-degree flare angle with Flare x Flare ends, accepting 3\/16 inch tube OD on both sides and threading at 3\/8-24 UNF. This union is rated for a maximum working pressure of 1900 psi and a maximum working temperature of 250 degrees F, making it suitable for hydraulic, refrigeration, and fuel line applications. Licensed plumbers, HVAC technicians, and fluid-system mechanics install this fitting when connecting or repairing small-diameter tubing runs in tight-tolerance systems.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial applications wherever 3\/16 inch flared tubing requires a straight union connection. Common install scenarios include refrigeration line repairs, fuel delivery systems, and hydraulic control circuits. The all-brass construction resists corrosion in both wet and dry service environments. Its compact size and standard SAE flare geometry make it a direct drop-in for field repairs and new installations alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree SAE flare angle with Flare x Flare ends for secure, leak-resistant connections\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch tube OD with 3\/8-24 UNF thread on both ends\u003c\/li\u003e\n  \u003cli\u003eRated to 1900 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eRated to 250 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003eAll-brass construction for corrosion resistance in fuel, refrigeration, and hydraulic service\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J512, SAE J513, and UL Listing standards\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 3\/16 inch OD flared tubing with 3\/8-24 UNF threaded connections and a 45-degree SAE flare angle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed technician familiar with flared tube fittings and the applicable system type. De-pressurize and isolate the line before disassembly. Inspect the flare seat on both tubing ends for cracks or deformation before threading the union; a damaged flare will not seal at rated pressure. Do not over-torque the fitting nuts, as brass flare fittings are susceptible to seat damage from excessive force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\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\u003eFlared Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1900 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\u003eStandards\u003c\/strong\u003e: SAE J512, SAE J513, UL Listing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: 155F-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540935213362,"sku":"155F-3","price":19.54,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/202132c8c7389b4689f491a26eff8044.jpg?v=1785866099","url":"https:\/\/voomisupply.com\/products\/parker-155f-3-brass-flared-tube-union-3-16-in-flare","provider":"Voomi Supply","version":"1.0","type":"link"}
