Mueller Streamline 150f-4-2 Flare to Female Pipe 90 Elbow 1/4 Inches Flare X 1/8 Inches Female Pipe

Product Description

The Mueller Streamline 150f-4-2 is a forged brass 90-degree elbow fitting that connects a 1/4 inch flare to a 1/8 inch female pipe thread. HVAC technicians, refrigeration mechanics, plumbers, and gas line installers use this type of fitting when they need to change direction in a line and transition between a flare connection and a female pipe thread connection. The 45-degree flare design creates a metal-to-metal seal between the flare nut and the body of the fitting. This type of seal is highly reliable under pressure and resists mechanical pull-out. The flare on the tube is clamped firmly between the nut and the body, which makes the connection dependable and safe. Flare fittings like the 150f-4-2 are widely used as alternatives to solder joints in situations where an open flame is not practical or not permitted. This is common in refrigeration systems, natural gas lines, propane installations, and fuel lines. The 1/4 inch outside diameter tube connection uses a 7/16-20 inch thread at the flare end, while the other end accepts a 1/8 inch female pipe thread. Compatible tube materials include copper, aluminum, brass, and welded steel hydraulic tubing that can be flared. The fitting is rated for media including water, air, inert and non-combustible gases, flammable liquids, and refrigerants such as Freon. With a maximum operating pressure of 1400 psi and a temperature range from -65 degrees Fahrenheit to 250 degrees Fahrenheit, this fitting handles demanding service conditions. It meets the functional requirements of SAE J512 and SAE J513. The brass body and brass nut provide corrosion resistance and long service life in both residential and commercial applications.
