As a sommelier and brewer, I may not be an expert in commercial design standards, but I can provide you with some insight into the compatibility of Swagelok fittings with other brands. It is important to note that while there may not be any specific commercial design standards for tube fittings, there is a guideline set by ASTM F1387.
ASTM F1387 states that intermixing of fittings from different manufacturers is prohibited unless authorized by the manufacturer. In the case of Swagelok, they do not authorize intermixing with other brands. This means that it is generally not recommended to use Swagelok fittings with fittings from other brands.
To further emphasize this point, it is worth mentioning that nobody has conducted a statistically valid and rigorous test methodology comparing Swagelok fittings with other brands. Swagelok provides product test reports that showcase the performance and reliability of their fittings, but these reports do not include comparisons with other brands.
In my personal experience, I have always found it best to stick with one brand when it comes to tube fittings. Mixing different brands can lead to compatibility issues, which can compromise the integrity and effectiveness of the fittings. This is especially crucial in industries where safety and reliability are of utmost importance, such as the oil and gas industry.
While it may be tempting to mix and match fittings from different brands to save costs or accommodate specific requirements, it is generally recommended to follow the guidelines provided by the manufacturer. Swagelok, for instance, is known for their high-quality fittings and their commitment to ensuring the compatibility and performance of their products.
To sum it up, Swagelok fittings are not typically recommended to be used with other brands unless specifically authorized by the manufacturer. It is always a good practice to consult the manufacturer’s guidelines and recommendations to ensure the safety and reliability of your tube fittings.
