Flare Connection & Installation Compatibility
This fitting is intended for compatible flare-type fluoropolymer tubing connections. Tubing outside diameter, wall thickness, flare preparation and chemical compatibility should be verified before installation. Metric and fractional tubing sizes are separate dimensional standards and should not be considered interchangeable. Pressure and temperature ratings are not stated here because these values have not been confirmed for this fitting series. For pressurized, vacuum-critical or safety-critical installations, verify the complete tubing and fitting system under the intended operating conditions before use.
