Machined from brass, this adapter is rated to 400 psi and handles temperatures from -65 to 250 degrees F, making it suitable for a wide range of fluid and gas line applications. The hex body measures 0.68 inches across flats, and the center-to-end dimension is 0.96 inches. Plumbers, HVAC technicians, and refrigeration mechanics routinely use fittings of this type to interface compression tubing runs with threaded manifolds, valves, or equipment ports.\u003c\/p\u003e\u003cp\u003eThis adapter is intended for use with copper, aluminum, and thermoplastic tubing in residential and light commercial systems. Typical install scenarios include instrumentation lines, fuel lines, refrigerant-adjacent control tubing, and hydraulic or pneumatic low-pressure circuits. The 3\/8-24 compression thread mates with standard 3\/16 inch tube ferrules, while the 1\/4-18 NPT female end accepts standard tapered male pipe threads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/16 inch compression inlet to 1\/4 inch FNPTF outlet configuration\u003c\/li\u003e\n\u003cli\u003eRated to 400 psi working pressure\u003c\/li\u003e\n\u003cli\u003eTemperature range: -65 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eBrass construction resists corrosion in fluid and gas service\u003c\/li\u003e\n\u003cli\u003eCompatible with copper, aluminum, and thermoplastic tubing\u003c\/li\u003e\n\u003cli\u003e0.68 inch hex for standard wrench engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with copper, aluminum, and thermoplastic tubing in compression fitting applications requiring a 3\/16 inch compression to 1\/4 inch FNPTF transition.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician familiar with compression fittings and NPT thread connections. Shut off and depressurize the line before disassembly or fitting installation. Apply an appropriate thread sealant to the FNPTF threads per the fitting manufacturer and applicable plumbing code requirements; do not overtighten, as brass threads can be damaged by excessive force. Verify all connections are leak-free under system pressure before returning the line to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: FNPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread\u003c\/strong\u003e: 3\/8-24 x 1\/4-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.68 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to End\u003c\/strong\u003e: 0.96 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 400 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -65 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Tubing\u003c\/strong\u003e: Copper, Aluminum, Thermoplastic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 18144\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67949895844146,"sku":"18144","price":15.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61a8f88705e6d25f7066835e1f984d92.jpg?v=1791703806","url":"https:\/\/voomisupply.com\/products\/midland-industries-18144-brass-compression-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
