Silicone Hose 45 deg Elb 4in ID

The Vibrant Performance Silicone Hose 45 Degree Elbow with 4-inch Inner Diameter is a high-performance coolant routing component engineered for custom cooling system fabrication and engine bay plumbing applications. This 45-degree elbow features a 4-inch ID with symmetrical 3.5-inch legs, allowing flexible routing around tight engine compartment layouts while maintaining optimal flow dynamics in high-temperature environments.

Constructed from reinforced silicone, this tubing elbow withstands sustained coolant temperatures and resists degradation from glycol-based cooling fluids, extended UV exposure, and thermal cycling common in performance and off-road vehicle cooling systems. The smooth internal bore minimizes turbulence and pressure drop, critical factors in maintaining efficient heat transfer. The black silicone finish integrates seamlessly into modern engine bays while providing excellent visibility for leak detection and maintenance inspection.

This component serves builders working on custom cooling configurations for performance vehicles, off-road trucks, marine engines, and industrial cooling applications where stock hose routing proves inadequate or incompatible. The 45-degree angle and 4-inch capacity make it suitable for large-displacement engines and applications requiring substantial coolant volume. Vibrant Performance hose fittings are industry-standard in fabrication and restoration shops, where precise fitment and reliable temperature performance directly impact engine longevity and system reliability.
