Final answer:
No, ISO and Double Flare fittings are not interchangeable. They have different angles and dimensions, and require different tools and techniques for installation.
Step-by-step explanation:
No, ISO and Double Flare are not interchangeable. They are two different types of fittings used in hydraulic systems. ISO (International Organization for Standardization) fittings have a 24-degree cone-shaped end and are commonly used in Europe, while Double Flare fittings have a 37-degree cone-shaped end and are commonly used in North America.
To give you an example, if you have a hydraulic system with ISO fittings, you cannot simply replace them with Double Flare fittings, as the angles and dimensions of the fittings are different. The two types of fittings require different tools and techniques for installation.
