Question by: Hugh G on Jul 16, 2025, 11:11 AM

trying to match up some stainless tubing i already have. is this one 3/4 OD with about a .065 wall and .62 ID?

Answer by: Customer Support on Jul 18, 2025, 8:58 AM

Specs line up as 0.75 inch outside diameter, 0.065 inch wall thickness, and 0.62 inch inside diameter for this seamless 316 stainless tube.

Question by: Howard C on Jan 26, 2026, 6:07 AM

what's the max working pressure on this tubing, and is that number already accounting for some kind of safety buffer?

Answer by: Customer Support on Jan 27, 2026, 3:44 PM

The working pressure is rated at 2,167 PSI, and yes, that figure already reflects a 6:1 safety factor built into the calculation. The burst pressure on this tubing is 13,000 PSI, so there's a substantial margin between normal operating conditions and actual failure. Worth knowing: if your application involves severe hydraulic shock or heavy mechanical strain, a more conservative 8:1 safety factor applies, which would bring your working pressure down from that 2,167 PSI figure. On the flip side, if shock and strain are minimal, a 4:1 factor can be considered, allowing for higher working pressures. The pressure ratings are calculated using the Barlow formula, based on the 0.065-inch wall thickness, 75,000 PSI tensile strength of the 316 stainless, and the 0.75-inch outside diameter.
