Machined from lead-free brass, it meets potable-water and refrigerant-line standards where lead-free materials are required. Thread sizes are 5\/8-18 on the flare side and 1\/2-14 on the NPTF side. Rated for service from -40 to 250 degrees F, this adapter handles a range of fluid and gas applications. Plumbers, HVAC technicians, and refrigeration mechanics commonly install this fitting during line connections where a transition from flared tubing to a male pipe thread is required.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for residential and light commercial plumbing, HVAC refrigerant lines, and gas distribution systems where SAE 45-degree flare connections terminate at a male NPTF port. It is compatible with copper, brass, aluminum, and steel tubing, making it a versatile transition piece across multiple trade disciplines. The half-union design allows the fitting to be disconnected from the tubing side without disturbing the threaded pipe connection, which simplifies future service access.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLead-free brass construction meets lead-free requirements for potable water and regulated installations\u003c\/li\u003e\n\u003cli\u003eSAE 45-degree flare seat on the 3\/8-inch side provides a leak-resistant metal-to-metal seal\u003c\/li\u003e\n\u003cli\u003e1\/2-inch male NPTF thread on the pipe side for a pressure-tight dry-seal connection\u003c\/li\u003e\n\u003cli\u003eRated -40 to 250 degrees F for use in both hot-water and refrigerant service\u003c\/li\u003e\n\u003cli\u003eCompatible with copper, brass, aluminum, and steel tubing\u003c\/li\u003e\n\u003cli\u003eHalf-union design allows tubing-side disconnect without disturbing the pipe connection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with copper, brass, aluminum, and steel tubing systems.

Shut off and depressurize the line before making or breaking any flare or threaded connection. Use an appropriate flare nut and tubing of the correct outside diameter to ensure a proper 45-degree flare seat engagement. Apply thread sealant rated for the media on the NPTF side; do not apply sealant to the flare seat itself.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 3\/8 inches (Male Flared, SAE 45-degree)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/2 inches (Male NPTF)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size 1\u003c\/strong\u003e: 5\/8-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size 2\u003c\/strong\u003e: 1\/2-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Lead-Free Brass\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\u003eCompatible Tubing\u003c\/strong\u003e: Copper, Brass, Aluminum, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 704048-0608\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67949782106418,"sku":"704048-0608","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9799b6dbd64792cf5171751d8e0dfea_bd442853-8dc9-4c31-9e2e-a4b8cd5d65fe.jpg?v=1791701281","url":"https:\/\/voomisupply.com\/products\/midland-industries-704048-0608-flare-half-union-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
