3in Silicone Hump Hose Black

The 3in Silicone Hump Hose Black is a premium tubing coupler designed for high-performance coolant, vacuum, and fuel line applications in automotive and motorsports environments. This straight hump connector serves as a flexible junction between rigid tubing sections, absorbing vibration and thermal stress while maintaining system integrity. Built by VIBRANT PERFORMANCE, a trusted name in performance cooling and plumbing solutions, this silicone hose coupler is engineered for durability in demanding under-hood conditions where standard rubber or plastic fittings fall short.

Constructed from reinforced silicone, the 3in Silicone Hump Hose Black delivers superior heat resistance, chemical compatibility, and flexibility compared to conventional rubber compounds. The distinctive hump design—a gradual, curved transition—distributes pressure evenly across the coupling joint, reducing stress concentrations and minimizing the risk of separation or leakage during acceleration, braking, or temperature fluctuations. With a 3-inch inner diameter and 3-inch length, this coupler accommodates standard tubing sizes while remaining compact enough for tight engine bay installations. The black silicone finish resists UV degradation and maintains appearance over extended use.

This hose coupler is ideal for custom cooling systems, turbo intercooler piping, fuel bypass lines, and vacuum distribution networks in street cars, drag racing platforms, and high-horsepower builds. Installation requires no special tools—simply slide the hump hose over your tubing ends and secure with hose clamps (not included). Compatible with any 3-inch ID tubing, including aluminum, plastic, and rubber lines, this connector works seamlessly in both OEM-style and custom-fabricated systems. Its lightweight construction (0.27 lbs) and compact dimensions (6.4 x 3.85 x 8.9 in) make it a space-efficient solution for engine bays where real estate is premium and reliability is non-negotiable.
