Look here for a variety of 45° Brass Flare Fittings for use with copper, brass, aluminum or steel tubing. These fittings are primarily used with fuel equipment, plumbing, gases, refrigeration and vacuum lines.
45° Brass Flare Fittings resist mechanical pull-out, yet they're easy to disassemble. They can be reassembled many times with no effect on their seal. Standard fittings use short nuts, while long nuts are offered here for higher vibration applications. Temperature range is from -65° to 250°.
