It features a 45-degree flare angle and a 5\/8-18 UNF thread, accepting 3\/8 inch OD tubing on the flare end. The reduced outside diameter on the solder end measures 1\/4 inch, making this an adapter-style fitting suited for transitioning between tube sizes or connection types. Constructed entirely from brass, it provides reliable corrosion resistance in both wet and refrigerant-handling environments. HVAC technicians and plumbers install this fitting when joining flared copper lines to soldered copper assemblies.\u003c\/p\u003e\n\u003cp\u003eThis fitting is commonly used in residential and light commercial HVAC systems, refrigeration lines, and copper plumbing installations where a transition from a flared connection to a soldered joint is required. It is well-suited for service and retrofit work where one side of a line set or refrigerant circuit terminates in a flare and the downstream piping requires a brazed or soldered connection. The compact brass construction makes it appropriate for tight spaces in equipment cabinets and mechanical chases.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree flare angle matches standard SAE flare fittings used in HVAC and refrigeration\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch OD flare end accommodates common copper refrigerant and plumbing tubing sizes\u003c\/li\u003e\n  \u003cli\u003e5\/8-18 UNF thread provides a secure, leak-resistant mechanical connection on the flare side\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch reduced OD solder end allows direct soldering or brazing to downstream copper tubing\u003c\/li\u003e\n  \u003cli\u003eFull brass construction resists corrosion in refrigerant and water service environments\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 HVAC, refrigeration, and copper plumbing systems requiring a 45-degree flare-to-solder adapter with 3\/8 inch OD flare and 5\/8-18 UNF thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber. Recover any refrigerant and isolate the system before disassembling flare connections. Torque the flare nut onto the 5\/8-18 UNF thread using an appropriately sized flare-nut wrench rather than adjustable pliers to avoid distorting the fitting. Solder or braze the solder-cup end using techniques consistent with local mechanical codes and manufacturer guidelines for the tubing material in use.\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\u003eFlare Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter (Flare End)\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduced Outside Diameter (Solder End)\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\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-6-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541220065586,"sku":"43F-6-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b20d2b805f1f39e8559f601a91c20da8.jpg?v=1785870247","url":"https:\/\/voomisupply.com\/products\/parker-43f-6-4-brass-flare-to-solder-fitting-3-8-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
