It connects 3\/16-inch compression tubing on one end to a 1\/8-inch female NPTF port on the other, providing a leak-resistant, thread-sealed joint without flaring the tubing. Constructed from brass, this adapter is rated for 150 psi and handles temperatures ranging from -40 degrees F to 150 degrees F. Licensed plumbers, HVAC technicians, and refrigeration mechanics use this fitting when transitioning small-diameter tubing into threaded port connections in control, fuel, or fluid-handling circuits.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for residential and light commercial applications where aluminum or copper tubing must terminate at a female NPTF threaded port. Common install scenarios include instrument tubing, fuel-line connections, pneumatic control circuits, and HVAC refrigerant or oil-line sub-assemblies. The Poly-Flo interchangeable design allows the compression sleeve and nut to be replaced or reused across compatible fittings in the same series without special tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlareless compression design on the 3\/16-inch side eliminates the need for tube-flaring tools\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch female NPTF thread provides a pressure-tight connection to standard tapered pipe ports\u003c\/li\u003e\n  \u003cli\u003eBrass construction offers corrosion resistance and durability in both wet and dry service environments\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi for reliable performance in low-to-medium pressure systems\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range of -40 degrees F to 150 degrees F suits varied service conditions\u003c\/li\u003e\n  \u003cli\u003eInterchangeable sleeve and nut components compatible with other Poly-Flo series fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with aluminum and copper tubing at 3\/16-inch compression and 1\/8-inch female NPTF threaded port connections in flareless brass fitting assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified refrigeration mechanic. Depressurize and isolate the line before disassembly or fitting installation. Ensure tubing is cut cleanly and deburred before seating the compression sleeve to achieve a proper seal. Apply an appropriate thread sealant to the NPTF threads as required by local plumbing or mechanical codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Compression (Flareless)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Female NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range\u003c\/strong\u003e: -40 degrees F to 150 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Tubing\u003c\/strong\u003e: Aluminum and Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 20257\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948952256818,"sku":"20257","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aff02a1eb0564cf00d43a4a99eda00e9_d6154287-489c-4ddb-9259-2bcf91034d36.jpg?v=1791677882","url":"https:\/\/voomisupply.com\/products\/midland-industries-20257-female-adapter-brass-compression","provider":"Voomi Supply","version":"1.0","type":"link"}
