Product Questions & Answers (1)

Question by: Tony R on Dec 3, 2025, 5:59 PM
Will this bulkhead fitting hold up okay in a hydraulic system running around 3000 PSI?
Answer by: Customer Support on Dec 5, 2025, 6:35 AM
This Eaton Aeroquip adapter is designed for use in hydraulic systems, instrumentation, and even chemical processing setups, so 3000 PSI should be well within its operating range.
