Stainless steel braids added to corrugated metal hoses significantly improve the pressure that the hose can withstand. High pressure flexible hose are usually single or double braided for higher pressure capabilities. Its corrugated bore can be T321 in annular construction, while the braided layers use 304. Standard pitch (close pitch) is designed for great flexibility.
High pressure braided hoses are capable of withstanding extraordinarily high temperature and pressure applications, such as hydraulic systems.
High pressure flexible hose – standard pitch or closer pitch for great flexibility
Note: The data below are based on 70°F. Pressure will decrease as the ambient temperature increases. Consult the Derating Factor between Temperature and Pressure for the right hose.
