Seamless 316 Stainless Steel Tubing, 0.56 Inch OD, 0.07 Inch Thick, 0.43 Inch ID

Based on the Barlow formula, the burst pressure for this tubing is 15,600 PSI, but keep in mind the maximum working pressure is 2600 PSI, with a 6:1 safety factor. Always refer to safety information when selecting tubing.

The rated working pressure is 2600 psi, and yes, that figure already reflects a 6:1 safety factor applied to the burst pressure of 15,600 psi. That safety margin is calculated for conditions where hydraulic shock and mechanical strain are considered considerable. If your application runs into more severe shock conditions, the manufacturer recommends stepping up to an 8:1 safety factor, which brings your working pressure down from that 2600 psi figure. On the flip side, if shock and strain are genuinely minimal in your setup, a 4:1 factor and higher working pressures can be carefully considered.

For sizing, you are looking at a 0.5625 inch outside diameter with a 0.4325 inch inside diameter, using a 0.065 inch wall thickness.
