Frequently Asked Questions

What is a flareless union fitting?

A flareless union fitting connects tubes without requiring flaring of the tube end. It uses a ferrule that compresses onto the tube to create a leak-proof seal, ideal for high-pressure applications.

Can this fitting be used with stainless steel tubing?

Yes, the brass fitting can be used with stainless steel tubing, but ensure compatibility to avoid galvanic corrosion. Use appropriate anti-seize compounds if needed.

What is the maximum working pressure for this fitting?

While specific pressure ratings depend on tube material and wall thickness, brass flareless fittings typically handle up to 3000 psi (207 bar) in hydraulic systems. Verify with your system requirements.

Is this fitting suitable for fuel lines?

Yes, brass is compatible with diesel and gasoline. However, for continuous exposure to aggressive fuels, confirm with the manufacturer's chemical compatibility charts.
