The Art of Material Science

Durion® Silicone Heater Hoses build on our decades of innovation in material science. This long-service-life hose is constructed of specially formulated silicone rubber with three-ply aramid textile cord reinforcement. This makes for an exceptionally durable fluid power solution that offers maximum performance across a wide operating temperature range.

Inspecting Your Hose.

As part of our Be System Smart initiative, we recommend regularly inspecting your critical vehicle systems, including your cooling system and hoses, at around 60,000 miles. As your coolant hose begins to age, the constant transfer of chemicals fluids will corrode your hose from the inside out. When inspecting your coolant hose, there are a few simple signs that it's ready for replacement:

Press for Soft Spots: The radiator hose is naturally rigid, and any soft spots along the hose body indicate the inner material has begun to break down. Firmly press on the hose body to feel for potential deteriorations.

Check the Ends and Fittings: Look for cracks around the hose end, especially near the hose clamps.

Feel for Bulges: Run your hands along the hose body to feel for protruding materials, which indicate a rupture within the hose that will eventually lead to failure.
