Buying advice

When choosing flared tube fittings consider material, pressure rating, and size compatibility. Stainless steel provides the highest durability and pressure tolerance, while brass is suitable for corrosion-prone environments. Match the fitting’s pressure rating to your system and ensure the flare angle (typically 45°) matches the tubing.
