• Heat and ozone resistant cover
• Engineered to resist electrochemical degradation - the leading cause of hose failure
• SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications
• Temperature rating: -40° C to 135° C in coolant hose applications

​The primary cause of coolant hose failure is an electrochemical attack on the rubber compound in the hose. 

This phenomenon is known as electrochemical degradation or ECD. It occurs because the hose liquid coolant and engine/radiator fittings form a galvanic cell or “battery”.

This creates a chemical reaction which causes micro-cracks to form in the hose tube. Coolant seeps into these cracks or stryations and begins to break down the reinforcement.

This leads to hose failure and ultimately roadside breakdowns.
