It threads onto a 7\/16-20 flare fitting to terminate a line or block a port during service or installation. Constructed from lead-free brass, this plug meets material requirements for potable water and refrigerant applications. Its rated operating range spans -40 to 250 degrees F, making it suitable for both low-temperature refrigerant lines and hot-water plumbing circuits. Plumbers, HVAC technicians, and refrigeration mechanics typically carry this fitting as a standard service component.\u003c\/p\u003e\n\u003cp\u003eThis plug is intended for use with aluminum, brass, copper, or steel tubing in 45-degree flare configurations. Common applications include capping unused ports on manifolds, sealing service valves during pressure testing, and terminating branch lines in refrigeration or hydronic systems. The 1\/4-inch connection size fits standard quarter-inch flare tubing commonly found in residential and light commercial HVAC and refrigeration equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free brass construction for compliance with low-lead material requirements\u003c\/li\u003e\n  \u003cli\u003e45-degree flare connection type for a leak-resistant mechanical seal\u003c\/li\u003e\n  \u003cli\u003e7\/16-20 thread for standard quarter-inch flare fittings\u003c\/li\u003e\n  \u003cli\u003eCompatible with aluminum, brass, copper, and steel tubing\u003c\/li\u003e\n  \u003cli\u003eRated from -40 to 250 degrees F for broad application coverage\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.018 pounds for easy field carry and inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with aluminum, brass, copper, or steel tubing in 45-degree flare systems with a 1\/4-inch connection size and 7\/16-20 thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is typically installed by licensed plumbers or HVAC technicians. Depressurize and isolate the line before removing or installing any flare fitting. Hand-tighten first, then use a flare nut wrench to snug the connection without overtightening, which can crack the flare seat. Verify the mating flare is properly formed and free of burrs before seating the plug.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: 45-degree flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -40 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Lead-free brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Tubing Materials\u003c\/strong\u003e: Aluminum, brass, copper, steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.018 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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LF39-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948857950514,"sku":"LF39-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a021004d658b93cf53dd6ebf5f26f1eb_dc40e3c9-2b56-4cc4-9cfb-a1d2bcea26dc.jpg?v=1791675099","url":"https:\/\/voomisupply.com\/products\/midland-industries-lf39-4-flare-plug-1-4-in-45-deg-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
