It accepts 1\/4-inch tube OD on both ends with a 45-degree flare angle and 7\/16-20 UNF threads, conforming to SAE J512 and SAE J513 standards. Rated for a maximum working pressure of 1,400 psi and a maximum working temperature of 250 degrees F, this fitting is built for reliable service in refrigeration, HVAC, and fluid-handling lines. Licensed HVAC technicians and plumbers install this union when splicing or extending flared copper or aluminum tubing runs in the field.\u003c\/p\u003e\u003cp\u003eThe 42F-4 is used in residential and light commercial HVAC systems, refrigeration circuits, and hydraulic or pneumatic fluid lines where a flare-to-flare union connection is required. Its compact overall length of 1.17 inches makes it suitable for tight installation spaces. The fitting is appropriate wherever SAE 45-degree flare connections are specified, including suction and liquid line repairs, refrigerant piping, and low-pressure pneumatic circuits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree SAE flare angle on both ends, conforming to SAE J512 and SAE J513\u003c\/li\u003e\n\u003cli\u003eRated to 1,400 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eRated to 250 degrees F maximum working temperature\u003c\/li\u003e\n\u003cli\u003eBrass construction for corrosion resistance and compatibility with copper tubing systems\u003c\/li\u003e\n\u003cli\u003eCompact 1.17-inch overall length suits confined install spaces\u003c\/li\u003e\n\u003cli\u003eUL Listed; meets SAE J512, SAE J513, and UNF thread standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or field-service fitting for SAE 45-degree flare tube union applications using 1\/4-inch OD tubing with 7\/16-20 UNF threads.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber familiar with flared tubing connections. De-energize the system and recover any refrigerant charge before breaking the line, in accordance with EPA Section 608 requirements. Use a calibrated flaring tool to produce a clean, crack-free 45-degree flare seat before assembling the union. Do not overtighten flare nuts; hand-tighten first, then use a wrench to snug the connection without distorting the flare seat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: 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 OD\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\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: 1,400 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: 1.17 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 J512, SAE J513, UL Listed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 42F-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542968729906,"sku":"42F-4","price":21.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf4fd8ab83268efdc349a4be42905e8d.jpg?v=1785912593","url":"https:\/\/voomisupply.com\/products\/parker-42f-4-brass-flared-tube-union-1-4-in-45-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
