Pressure:
Working pressure up to 2000 psi depending on TUBE size.depending on size. Will withstand burst pressure of standard tubing-up to 5000psi with bundy-weld (double flare) and 3500 psi with copper tubing.
Vibration:
Good resistance-use long nut when greater vibration resistance is required.
Temperature Range:
-65℉ to +250℉（-53℃ to + 121℃）range at maximum opreating pressures.
Hex plug with SAE 45-degree flare male end terminates tube size fitting
Brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability
For use with LP and natural gas, refrigeration, and hydraulic applications
Used With: Copper, brass, aluminum and steel hydraulic tubing that can be flared.
Low cost and reusability, long or short nut. Good resistance to vibration.
