Manufactured by Mid-America Fittings from CA360 brass, this fitting connects a 1\/2 inch male flare end to a 3\/8 inch male pipe thread (MPT), making it a reliable reducing union for installations where two different pipe sizes must be joined. CA360 brass is a free-machining alloy known for its corrosion resistance, durability, and ability to maintain a strong seal under pressure and temperature extremes. This fitting is built to handle working pressures up to 750 PSI and temperatures ranging from -65 to 250 degrees Fahrenheit, making it suitable for demanding field conditions. The 45-degree flare angle conforms to standard SAE and industry specifications, ensuring compatibility with flare fittings commonly used by HVAC technicians, plumbers, and instrumentation professionals. The hex size measures 0.75 inches, allowing for easy wrench engagement and secure tightening without the risk of slipping. The thread size is 3\/4 inch at 16 TPI on the flare end, consistent with SAE and MS standards. Approved applications include liquid propane, natural gas, flammable liquids, refrigeration lines, power steering systems, hydraulic systems, pneumatic systems, and instrumentation. This fitting meets ASA, ASME, SAE, and MS standards, confirming its suitability for regulated and safety-critical installations. HVAC technicians frequently use half union reducing fittings like the 408-86 when transitioning between line sizes in refrigerant or gas piping systems. The male flare by male threaded configuration allows this fitting to connect to a wide variety of standard components without additional adapters. Its compact design and high-quality brass construction make it a dependable choice for both new installations and service work in the field.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eConnects 1\/2 inch male flare to 3\/8 inch male pipe thread for reliable reducing union connections\u003c\/li\u003e\n\u003cli\u003eRated to 750 PSI and -65 to 250 degrees Fahrenheit for use in demanding HVAC, refrigeration, gas, and hydraulic applications\u003c\/li\u003e\n\u003cli\u003eManufactured from CA360 brass to ASA, ASME, SAE, and MS standards for broad compatibility and code compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Brass 408-86 half union reducing male adapter delivers a pressure-rated, standards-compliant connection between 1\/2 inch flare and 3\/8 inch MPT lines.
