1 1/2in Dia. X 6in Lengt h Silicone Hose

The 1 1/2in Dia. X 6in Length Silicone Hose from Northern Radiator is a professional-grade coolant and fluid transfer component engineered for high-performance automotive cooling systems. Whether you're building a custom engine bay, upgrading factory cooling plumbing, or fabricating a specialized circulation loop, this versatile hose segment delivers the flexibility and heat resistance required in modern engine modifications. Mechanics and engine builders rely on silicone hose for its superior temperature tolerance and durability compared to traditional rubber alternatives, making it essential for turbocharged, supercharged, and high-output builds where factory cooling inadequacies demand reinforced solutions.

Constructed from industrial-grade silicone, this 6-inch hose segment features a 1.5-inch inner diameter (ID) and is finished in black for both durability and aesthetic integration into engine compartments. Silicone's inherent properties allow continuous operating temperatures significantly higher than conventional rubber—critical when routing coolant near headers, turbochargers, or other heat sources common in modified powerplants. The smooth internal bore minimizes turbulence and flow restrictions, optimizing heat transfer efficiency while the reinforced construction prevents collapse under vacuum and handles pressure cycling without degradation. At 0.36 lbs, the lightweight profile makes it ideal for weight-conscious builds without sacrificing structural integrity or performance.

This Northern Radiator hose segment suits custom cooling loops, intercooler piping, heater bypass configurations, and any auxiliary coolant circuit where precision routing and thermal resilience are non-negotiable. The 6-inch length accommodates tight engine bay layouts while the 1.5-inch diameter pairs seamlessly with standard hose fittings and barbed adapters found in most motorsports and performance cooling kits. Professional installers and DIY enthusiasts alike benefit from its compatibility with standard silicone hose clamps and its resistance to coolant additives, ensuring reliable service life across countless heat cycles and demanding operating conditions.
