• Recommend for upper, lower, by-pass, heater and other coolant hose applications.
• Heat and ozone resistant cover.
• Engineered to resist electrochemical degradation - the leading cause of hose failure.
• Re-engineered materials resist vacuum collapse. This reduces the need for internal springs in many applications.
