4in ID x 3in Long Silicone Straight Hose

The 4in ID x 3in Long Silicone Straight Hose from VIBRANT PERFORMANCE is a premium radiator and cooling system coupler engineered for serious automotive builders and enthusiasts who demand reliability in high-temperature applications. This straight silicone hose serves as a critical connector in custom cooling loops, turbo intercooler setups, and modified engine bay configurations where factory tubing won't fit or function optimally. Whether you're upgrading a street rod, fabricating a custom cooling solution, or installing performance modifications, this hose provides the flexible, temperature-resistant connection your build requires.

Constructed from premium silicone material, the 4in ID x 3in Long Silicone Straight Hose withstands extreme thermal cycling and coolant chemistry without degradation or loss of structural integrity. The 4-inch inner diameter accommodates substantial coolant flow rates essential for high-output engine builds, while the 3-inch length provides precise spacing control in tight engine compartments where standard radiator hoses lack flexibility. Silicone construction eliminates the brittleness and permeability issues common in rubber compounds, maintaining consistent performance across ambient temperature ranges and extended duty cycles. The smooth internal bore minimizes turbulence and pressure drop, critical factors in maintaining optimal cooling efficiency under sustained load or competition use.

Mechanics and fabricators building custom cooling systems, intercooler piping, and modified engine configurations will appreciate the precision fit and durability this coupler delivers. Installation requires standard hose clamps (not included) and works seamlessly in systems using 4-inch diameter tubing or hose stock. The compact 3-inch length makes this hose ideal for applications where space constraints demand shorter transitions between components, from turbo charge cooling lines to auxiliary radiator loops. VIBRANT PERFORMANCE's reputation for manufacturing standards ensures consistent wall thickness and dimensional accuracy across every unit.
