Applications
Silicone heater hose is used for cab and sleeper heater lines, low-pressure coolant branches, and any application where rubber EPDM heater hose would degrade under high under-hood temperatures:
- Heavy-duty truck cab heater and APU coolant lines
- Sleeper bunk heater plumbing
- School bus, transit bus, and motorcoach heater systems
- Marine cabin heater and engine pre-heat plumbing
- Industrial and stationary engine coolant lines
Verify inside diameter, length, and hose orientation before installation. Use clamps rated for silicone hose; cut clean and square.
