Note: Technical information to be used as a guide only.  Pressure values given are based on the short term burst pressure at +20°C based on a 3:1 safety factor.  Any increase in temperature above +20°C will result in lower pressure values. These values may also vary depending on the hose manufacturer.  If the pressure rating is critical to your applicaiton please specify the required rating at time of enquiry.
