7/8in (22mm) ID x 5 ft l ong Silicone Heater Hose

The VIBRANT PERFORMANCE 7/8 inch ID x 5 foot long silicone heater hose (part number 20465) is a high-temperature coolant line designed for precision engine cooling applications. This 22mm silicone hose delivers reliable thermal management in engine compartments where standard rubber tubing cannot withstand sustained elevated temperatures. The silicone construction resists heat cycling better than conventional rubber, making it ideal for performance cooling systems, custom builds, and applications requiring durable heater hose replacement.

Specifications are engineered for direct compatibility with 7/8 inch ID (inner diameter) connections, a standard heater line size found in many domestic and imported engines. The five-foot length accommodates flexible routing through the engine bay without requiring multiple spliced sections, reducing potential leak points. The black silicone material provides UV and ozone resistance, extending service life in under-hood environments. VIBRANT PERFORMANCE silicone hose is reinforced to handle the pressure cycling inherent in closed-loop cooling systems while maintaining flexibility for vibration isolation and routing around engine obstacles.

This hose serves engine builders, restoration specialists, and vehicle owners upgrading cooling systems for street rods, custom motorcycles, marine engines, and modified performance vehicles. It is particularly valued in applications where factory heater hose routing is restrictive or where higher-temperature tolerance is required. The 5-foot continuous section reduces assembly complexity compared to shorter hose segments, and silicone's superior flexibility aids installation in tight engine bays. Buyers should verify inner and outer diameter compatibility with their specific heater line connections before installation to ensure proper fit and sealed connections.
