Heavy Duty Materials: Our heater hose features a high-density polyester layer between premium silicone walls. This 3-layer design provides extreme burst strength, preventing expansion under high-pressure conditions in automotive cooling systems
Temperature Resilience: Maintains flexibility and integrity from -40°F to 230°F. Unlike standard rubber that cracks, this high-temp silicone tubing resists aging, ensuring reliable performance in harsh engine environments
Longer Size: Designed with a 19mm ID and 27mm OD, this 12ft roll offers ample length for custom routing. The smooth bore maximizes flow for coolant or vacuum lines, making it a great choice for engine bypass systems
Universal Multi-Purpose: This versatile blue silicone hose is perfect for automotive radiator systems, engine vacuum lines, turbocharger coolant paths, and even industrial water transportation. It is compatible with water and anti-freeze
Friendly Reminder: To ensure a leak-free installation, please measure your existing fittings and ports before ordering. This hose is a 3/4'' ID size; using incorrect dimensions may lead to improper sealing
