Vortech Superchargers Coupling 5.00" to 4.00" Straight Sleeve - Blue 7S500-400
Blue Straight Reducing Silicone Coupler for Large-Diameter Boosted Plumbing
The Vortech Superchargers Silicone Coupling (PN 7S500-400) is a precision-molded straight silicone reducing sleeve designed to transition large-diameter intake or charge piping to slightly smaller tubing in supercharged and turbocharged systems. This coupler reduces from a 5.00-inch inside diameter to a 4.00-inch inside diameter, making it ideal for high-flow applications where smooth, secure transitions are critical.
Manufactured from reinforced, high-temperature silicone, this coupling is engineered to withstand the heat and pressure demands of forced-induction environments while retaining the flexibility needed to absorb engine movement and vibration.
Boost-Ready Silicone Construction
Unlike standard rubber connectors, Vortech silicone couplers are purpose-built for boosted applications. The reinforced silicone construction resists expansion under pressure, helping maintain consistent airflow and reducing the risk of leaks or coupler failure under load.
The straight reducing design ensures a smooth, controlled airflow transition between pipe sizes, supporting efficient airflow and long-term reliability in both high-performance street and race applications.
