When choosing between flare and flareless fittings, the decision largely depends on the specific application and the required tightness of the seal.
What Are Flare Fittings?
These fittings involve a tapered end that fits into a flared tubing, secured with a sleeve and nut to create a pressure-resistant, leak-tight seal. The tubing is flared using a tool like a mandrel or cone, often with pneumatic flaring tools. Flare fittings are highly reliable for long-term use and are suitable for inaccessible or mission-critical locations, such as in military, aerospace, heavy machinery, and industrial applications. They are ideal for connecting thin- to medium-wall tubing under high pressure and temperature, and are widely used worldwide in hydraulic systems, petro-chemical industries, and more.
Hydraxio’s SAE J514 JIC tube fittings are flare type. Want to learn more, please contact us for more details.
What Are Flareless Fittings?
Also known as compression fittings, these use a single ferrule and nut, removing the need for flaring. They are simpler to install than flare fittings and are compatible with various tubing types. Flareless fittings, like OmegaOne’s OmegaBite, are suitable for systems with high vibration and thicker tubing. They are commonly used in connections where slight leakage is not a significant concern, such as water and compressed air lines.
Choosing the Right Fitting:
The decision depends on the seal tightness required and the specific industry regulations. Flare fittings are preferable where any leakage is critical, like in gas and high-pressure lines. Flareless fittings are more suitable where minor leakage is acceptable. Compliance with industry standards and codes, especially in regulated sectors like aerospace and defense, is also a crucial factor in choosing the appropriate fitting type.
