3-1/2in Silcone Hump Hose Black

The Vibrant Performance 3-1/2in Silicone Hump Hose in Black (MPN 2735) is a precision silicone tubing coupler engineered for high-performance cooling and fluid transfer systems. This straight hump-style connector features a 3-1/2 inch inner diameter with a compact 3-inch length, making it ideal for automotive, marine, and industrial applications where space is limited but durability cannot be compromised.

Constructed from premium silicone material, this hose coupler withstands extreme temperatures and maintains structural integrity under pressure cycling—a critical requirement in radiator bypass loops, turbocharger charge piping, and inter-cooler connections. The hump profile provides reinforcement at stress points while the black finish resists UV degradation and presents a clean appearance in engine bays. The 3-1/2 inch ID accommodates standard cooling circuit diameters common to mid-sized performance engines and heavy-duty marine systems.

This silicone hump hose is purpose-built for technicians upgrading OEM cooling infrastructure on custom builds, restoration projects, and performance platforms where silicone flexibility and temperature tolerance exceed rubber alternatives. Marine environments particularly benefit from silicone's resistance to saltwater corrosion. The compact 3-inch length fits tight engine compartments and confined routing situations where longer couplers create fitment conflicts.

Vibrant Performance specializes in cooling system components trusted across motorsports and industrial sectors. Each hose coupler is individually bagged for protection during storage and shipment. Verify compatibility with existing hose clamp sizes and connection points before installation.
