A chemical hose with a max PSI of 150 and a max temperature of 150F cannot withstand continued use at both maximums.

Higher temperatures can have a dramatic impact on a hose assembly’s ability to handle pressure. Pressure ratings are usually shown at a moderate 70-72F degree temperature. Use the below chart to evaluate the effect of different temperatures with various media types. For assistance using the chart please chat with one of our experts or reach out with a question >> 



De-rating factor applies to hose system pressure ratings


How the De-Rating Chart Works:

The chart lists temperatures across the top and hose type down the left column. Based on your hose system application, locate the appropriate de-rating factor and multiply it by the hose system pressure rating in the pressure chart above.
