Description
Product Overview
The HRP 120‑inch silicone heater hose is engineered for automotive and industrial applications where durability and flexibility are paramount. Made from high‑grade silicone, the hose maintains its elasticity across a temperature range of -65°F to 500°F, resisting cracking, hardening, and degradation from ozone, UV exposure, and common automotive fluids. With a 3/8″ ID and a robust reinforced design, it delivers a reliable 50 psi maximum pressure rating, ensuring leak‑free operation in heater core plumbing, coolant transfer, turbo and intercooler connections. The bright blue exterior provides easy visual identification during installation and maintenance.
Usage
Designed for both professional mechanics and DIY enthusiasts, this hose excels in tight engine bays where routing flexibility is essential. It is perfect for replacing worn heater hoses, upgrading turbo‑intercooler lines, or creating custom coolant loops in performance builds. Its 120‑inch length allows for versatile routing without the need for multiple splices, reducing potential failure points.

FAQ
What vehicles are compatible with this hose?
The HRP silicone heater hose fits most passenger cars, trucks, and performance vehicles that use standard 3/8″ ID heater hoses. It is also suitable for custom cooling loops in motorsports applications.
Can the hose be bent around tight corners?
Yes, the high‑grade silicone remains supple even at low temperatures, allowing it to navigate tight bends without kinking or losing structural integrity.
Is this hose compatible with all coolant types?
Absolutely. The silicone material is chemically inert and resists degradation from ethylene glycol, propylene glycol, water‑based coolants, and common anti‑freeze additives.
How does the pressure rating compare to rubber hoses?
At 50 psi, the HRP silicone hose meets or exceeds the pressure specifications of most OEM rubber heater hoses, providing a safe margin for high‑performance applications.
Do I need any special tools to install this hose?
No special tools are required. Standard hose clamps and basic hand tools are sufficient for a secure installation.
