Vibrant Performance 2836 4-Ply Silicone Reducer Coupler, 3.5 to 4.5 Inch ID, 3-Inch Length

The Vibrant Performance 2836 tubing coupler is a straight reducer designed to connect tubing with different inside diameters in air intake, intercooler, turbocharger, and other high-performance plumbing applications. Its stepped design transitions from a 3.5-inch inside diameter to a 4.5-inch inside diameter, providing a secure and efficient connection between mismatched tubing sizes.
Constructed from durable black silicone, this 4-ply reducer coupling offers excellent flexibility, strength, and resistance to heat, pressure, and common automotive fluids. The reinforced multi-layer construction helps maintain the coupler’s shape under demanding operating conditions while minimizing the risk of collapse or deformation. Its smooth interior supports consistent airflow through the connected tubing.
The Vibrant Performance 2836 features a straight configuration and compact 3-inch overall length for installations where space is limited. It can be secured with compatible clamps, making it suitable for custom intake systems, charge-air piping, and other fabricated automotive plumbing. This coupler is sold individually and provides a dependable connection for performance and replacement applications.
