Seamless Carbon Steel Tubing, 0.75 Inch OD, 0.05 Inch Thick, 0.65 Inch ID

At 1198 PSI maximum working pressure, that figure already accounts for a 6:1 safety factor, which is the rating applied specifically for applications where considerable hydraulic shock and mechanical strain are present. The burst pressure on this tubing sits at 7,187 PSI, so there's real headroom built in. If your shock conditions are on the severe end, the spec notes that an 8:1 safety factor should be applied, which would mean running at lower working pressures than the 1198 PSI figure. For moderate shock environments, the 6:1 figure is what this tubing is rated and stocked for.

Made to SAE J524, it is seamless low carbon steel tubing that is annealed specifically for bending and flaring, so it is a good match for that kind of shop work.
