Brass SAE 45° Inverted Flare Fittings - 902
Brass SAE 45° fittings are designed for use on low pressure copper, brass, aluminum or steel tubing. They are most commonly used for fuel equipment, plumbing, gases, refrigeration and vacuum lines. Flare fittings are easy to disassemble and can be reassembled many times with no effect on the seal, however brass is a soft material and susceptible to distortion, cracking, cross threading, etc. when over tightened. As a general guide only, they may have an intermittent temperature range of -54°C (-65°F) to +121°C (+250°F), however at wide temperature ranges the maximum pressure rating drops significantly.
