2-3/4in ID X 3in Long Silicone Straight Hose

The 2-3/4in ID X 3in Long Silicone Straight Hose from VIBRANT PERFORMANCE is a precision coolant and fluid transfer coupling engineered for modern engine builds, custom cooling systems, and high-performance automotive modifications. Mechanics and engine builders rely on this straight hose for creating leak-free connections between radiators, heater cores, water pumps, and intercooler setups where direct inline coupling is required. Its compact 3-inch length makes it ideal for tight engine bays and turbo installations where space constraints demand efficient, no-fuss plumbing solutions.

Manufactured from premium automotive-grade silicone, this straight hose coupler features a 2-3/4-inch inner diameter and is reinforced internally to withstand sustained coolant pressure and thermal cycling without degradation or collapse. The silicone construction resists ozone, UV exposure, and coolant chemistry far better than OEM rubber, making it the preferred choice for both street and race applications where durability and reliability are non-negotiable. The black silicone material complements engine bay aesthetics while delivering superior flexibility compared to rigid metal fittings, allowing for vibration isolation and easier installation during complex plumbing layouts.

This hose is ideal for turbocharged and supercharged engine conversions, custom water cooling loops, and any radiator upgrade requiring mid-circuit coupling without excessive fitting bulk. The 2-3/4-inch bore accommodates substantial coolant flow rates essential for maintaining optimal engine temperatures under high load, while the reinforced silicone walls prevent pinching and collapse under pressure spikes. Whether you're assembling a street rod cooling system, modifying an LS swap, or upgrading a drift car's thermal management, this straight silicone hose delivers OEM-quality performance with the flexibility that aluminum hard-line plumbing simply cannot match.
