Hump Hose Coupler 4in ID x 6in Long

The Hump Hose Coupler 4in ID x 6in Long from Vibrant Performance is an essential coupling solution for custom cooling, intercooler, and intake manifold plumbing on high-performance engine builds. This product is designed for both professional mechanics and DIY fabricators who need reliable junction points in tight engine bays or custom coolant loops.

Constructed with a 4-inch inner diameter and 6-inch length, this hump coupler accommodates 4-inch ID silicone hose or tubing. Its expanded hump profile maximizes contact surface area for secure hose clamping, while the flexible design absorbs vibration and thermal expansion, reducing strain on connection points and preventing premature hose failure.

Ideal for turbo intercooler setups, radiator bypass loops, heater control modifications, and custom intake charge cooling systems, this coupler pairs seamlessly with 4-inch silicone hose secured by stainless steel hose clamps. Its durable materials resist coolant degradation, ozone cracking, and high-temperature cycling, making it suitable for both street and track applications.
