does this fitting handle 6000 psi or is that just a static rating? got some high-pressure lines i need to route at a 90 and want to make sure it'll hold up under load
Answer by: Customer Support on May 31, 2025, 12:17 PM
The 6,000 psi rating on this one is the maximum dynamic pressure, so it's rated for pressure under working conditions, not just static. Forged steel construction keeps it solid through pressure cycles, which is what you'd expect for a fitting meant to handle real hydraulic loads.
Question by: Keith C on May 29, 2025, 9:42 AM
What’s the highest pressure this fitting can handle without blowing apart?
Answer by: Customer Support on May 30, 2025, 10:02 AM
With its forged steel construction, this 90-degree elbow fitting is rated for dynamic pressures up to 6,000 psi.
