Underline is cover compound rating only. Many factors, such as temperature, concentration and length of exposure, are relevant to how chemical exposure affects the tube and
cover or fitting material. The fluid manufacturers recommended maximum operating temperature should be carefully observed. Exceeding the manufacturer's recommended
maximum temperature can result in fluid breakdown and cause harm or shorten life of tube and cover materials. There may be instances where the hose cover could be adversely
affected by fluids which would not chemically affect the hose tube. Conversely, some fluids with an adverse affect on the tube of the hose may not have a deteriorating effect on
the hose cover. It is recommended that the user test the hose/fluid compatability to their own standards. Since no industry standards exist for chemical resistance, the Compass
Chemical Resistance Guide for Elastomers is used whenever possible. Teflon® is a registered trademark of Dupont.
