At what pressure are CO2 hose assemblies tested?

The correct pressure at which CO2 hose assemblies are tested is 300 psi. This testing pressure ensures that the assemblies can withstand the high pressures they may encounter during operation without failing. The testing is a crucial safety measure to ensure that hoses are capable of containing the carbon dioxide and can function effectively in extinguishing fires. By testing at this pressure, manufacturers can identify any weaknesses or potential points of failure in the hoses, which is important for maintaining reliability and safety standards.

Understanding the importance of testing at 300 psi is essential for those involved in fire safety and equipment maintenance, as it helps ensure that fire extinguishing systems using CO2 will operate correctly in emergency situations.
