High Temperature Silicone Heater Hose 3/8'' ID, Heavy-Duty Vehicles & Industrial Equipment

Inclusive of all taxes

The High Temperature Silicone Heater Hose with a 3/8'' inner diameter is specifically designed for heavy-duty vehicles and industrial equipment requiring reliable heater and radiator system components. Engineered from high-grade silicone material with polyester braid reinforcement at 70 Durometer hardness, this hose withstands extreme temperatures ranging from -65°F to 350°F (-53.9°C to +176.6°C). It offers superior resistance against electrochemical degradation, ozone, UV rays, oil splashes, and engine fluids, ensuring exceptional durability and longevity in harsh industrial environments. The hose meets and exceeds SAE J20 R3 standards alongside various heavy-duty OEM requirements, confirming its suitability for demanding applications. Its flexible construction allows easy installation without kinking, and vibration absorption properties minimize wear caused by engine or machinery movements. Additionally, the hose is non-conductive and corrosion-resistant, making it safe for use near electrical systems and exposure to automotive chemicals. This robust silicone heater hose is an ideal component for professionals seeking reliable, long-lasting performance for vehicle heating and radiator system maintenance or replacement.
