4 Ply Hump Hose 5in I.D. x 3in long - Black

The 4 Ply Hump Hose 5in I.D. x 3in long in Black by Vibrant Performance is a specialized radiator hose connector designed for custom cooling system builds and engine swap applications. This silicone reinforced hose is essential for bridging gaps between radiator ports, water pump outlets, and engine block fittings where standard straight hoses won't fit.

Constructed with four-ply reinforcement, this hump hose is built to handle high-temperature coolant flow while maintaining structural integrity under boost or sustained high RPM operation. It delivers superior burst pressure resistance compared to single or two-ply alternatives, making it suitable for various performance applications. The 5-inch internal diameter accommodates substantial coolant volume, while the 3-inch length is specifically designed for tight engine bays and intercooler piping configurations.

This connector is particularly beneficial for LS engine swaps, turbo and supercharger installations, and custom radiator setups where off-the-shelf hose kits may not fit. The reinforced construction can handle coolant temperatures up to 250°F, ensuring compatibility with both OEM and aftermarket cooling components. Installation is straightforward—simply clamp both ends securely to complete the setup.
