SAE 45° Flare (SAE J512)
These flare fitting connectors are widely found in low pressure applications like refrigerant and fuel lines, as well as automotive piping system applications. Both halves have a 45° flare seat, and the threads of the each connector engage together to form a tight mechanical connection, with the seal forming on the 45° flare seat. The fittings are frequently made of brass, stainless steel and carbon steel.
Note: SAE 45° Flare fittings connectors are identical to JIC 37° Flare connectors, except for the angles of the seats.
