High pressure system hoses shall be tested at what PSI?

• A. 1000 PSI
• B. 3500 PSI
• C. 5000 PSI
• D. 2500 PSI

Answer: (D)

High-pressure hoses are hydrostatically tested to verify they can safely handle more than their normal operating pressure and to reveal any hidden defects in the hose, fittings, or crimp joints. The prescribed test pressure of 2500 psi provides a solid safety margin above typical service pressures, so if the hose or connections can hold that level without leaks or swelling, they’re considered sound for use in high-pressure systems.

Choosing 2500 psi ensures the assembly is robust enough to tolerate overpressure conditions that might occur in service, while lower tests (like 1000 psi) might not expose potential weaknesses, and much higher levels (such as 3500 or 5000 psi) are beyond what the standard requires for this type of hose and could unnecessarily stress the components.
