Question by: Daryl H on Jan 3, 2026, 12:06 PM
Will this fitting hold up in a hydraulic system that runs at a steady 4,800 PSI?
Answer by: Customer Support on Jan 5, 2026, 6:14 AM
This straight steel fitting is rated for dynamic pressures up to 5,000 PSI, so it should be suitable for your system as long as pressure spikes don't exceed that limit.
