Heavy-Duty Heater Hose is designed for coolant circulation on large engines on trucks, buses, diesel generators, and other industrial applications where a heavy-walled, robust hose is preferred. EPDM rubber provides excellent resistance to heat aging, anti-freeze solutions, ozone, and weathering. This hose can also be used for light-duty saturated steam service where pressures do not exceed 85 psi.
Inner tube: Black EPDM rubber designed to withstand hot water and low-pressure steam.
Outer cover: Smooth, heat, abrasion and weather resistant EPDM rubber with wrapped finish.
Temperature range: -40°C (-40°F) to 165°C (329°F)
