pressure ratings

Up to what pressure does the Swagelok double ferrule fitting hold??

With the right tube selection and assembly, you can always be confident: up to the bursting pressure of the pipe.
Detailed information on possible pressure ratings can be found in our catalogue. Webcatalog MS-01-107

Sample calculation:

Up to what pressure can I pressurize a 10x1 mm stainless steel tubing in conjunction with the Swagelok compression fitting?

Answer: The recommended working pressure for a seamless drawn stainless steel tube with a 10 mm outer tube diameter and 1 mm wall thickness is 240 bar (-28 to +37°C).

Source: Table 4, MS-01-107 data sheet; excerpt:

To determine the allowable operating pressure at high temperatures, multiply the allowable operating pressure by the factor given in Table 26.
