Product Description

The Vibrant Performance 11867 is a 4-ply aramid-reinforced silicone hump hose coupler designed to transition between 4.00in and 3.50in piping. Its flexible hump-style design helps accommodate movement and alignment variation in custom charge air cooler, intake, air, and water piping systems.

Built from reinforced silicone, this coupler is designed for demanding high-temperature and high-pressure applications. The 4-ply aramid construction provides a durable connection for performance-oriented plumbing systems while the flexible design helps simplify installation where rigid tubing alignment may vary.

This is a universal fabrication component rather than a vehicle-specific direct-fit part. Confirm the mating tube or pipe dimensions, clamp requirements, system pressure, temperature conditions, and available clearance before installation. The coupler is sold individually.
