The fitting accepts a 3\/8 inch tube OD on the flare end with a 5\/8-18 UNF thread and terminates in a solder-cup end sized for a 5\/16 inch reduced outside diameter. Rated to 1000 psi working pressure and 250 degrees F, it handles the demands of refrigerant lines, copper tubing runs, and similar pressure applications. HVAC technicians and plumbers install this fitting when connecting flared copper tubing to a soldered assembly or component.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial HVAC and refrigeration applications where SAE 45-degree flare connections interface with soldered copper piping. Typical install scenarios include refrigerant line sets, copper suction or liquid line transitions, and general fluid-system assemblies where mixed connection types are required. Its all-brass construction makes it compatible with copper tubing systems and resists corrosion in both indoor and mechanical-room environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree SAE flare end conforms to SAE J512 and SAE J513 standards\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch tube OD flare with 5\/8-18 UNF thread for secure mechanical connection\u003c\/li\u003e\n  \u003cli\u003eSolder-cup end with 5\/16 inch reduced outside diameter for clean sweat joints\u003c\/li\u003e\n  \u003cli\u003eRated to 1000 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eRated to 250 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003eUL Listed; meets SAE J512, SAE J513 standards\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1.17 inches minimizes space requirements in tight installations\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 45-degree SAE flare systems using 3\/8 inch OD copper tubing with a 5\/8-18 UNF flare nut, transitioning to a solder-cup connection on copper pipe or fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber following applicable mechanical codes. Evacuate and recover any refrigerant and isolate the system from pressure before disassembling flare connections. Ensure the flare nut is torqued to the fitting hand-tight before applying final wrench turns, and do not over-tighten the flare connection as brass fittings are susceptible to thread damage. The solder end must be fully cleaned and fluxed before applying heat; keep flame away from the threaded flare end during the sweat operation.\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\u003eEnd Connection\u003c\/strong\u003e: Flare x Solder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduced Outside Diameter (Solder End)\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1000 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: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE J512, SAE J513, 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: 43F-6-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538972377394,"sku":"43F-6-5","price":17.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e954e283053a5566a4fdaa6f76b7ec6_6ddb71cf-77ac-4757-b6c1-1144abb7b07e.jpg?v=1785831419","url":"https:\/\/voomisupply.com\/products\/parker-43f-6-5-brass-flare-to-solder-fitting-3-8-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
